Request for addition of information: basis of theory of evolution

Evolution is validated by more than one line of research. Fossils, DNA, biochemistry?, and, I believe, other areas. Would it be possible for someone familiar with evolution to put these in this article or, perhaps Evolution as fact and theory? Preferably, imo, as bullet points? I would like to be able to find the basis the theory in one easy to read place.

Also, the article Evolution as fact and theory is linked to in this article, but it is piped from fact. Would it be a good idea to add it to see also. Thank you Jim1138 (talk) 18:03, 29 August 2013 (UTC)

Frequently Asked Questions (FAQ)

Just for clarification, have any of these questions actually been frequently asked? Or have they been written by an editor, who subsequently wrote a response to them? I'm just a little confused by a set of eight "rephrased" questions that have allegedly been asked frequently, even though there is no record of any one of them having been asked in the form in which it appears here. — Preceding unsigned comment added by 72.38.56.84 (talk) 20:48, 18 September 2013 (UTC)

The "Frequently Asked Questions" addresses concerns and or complaints brought up by creationists, trolls for Jesus and various well-intentioned editors who have been deceived by creationist anti-science misinformation. And yes, all of the questions actually have been brought up in this and related talkpages in numerous, numerous reiterations.

The FAQ section is very well written - worthy of good article status in itself. MFlet1 (talk) 13:57, 1 October 2013 (UTC)

I am curious how you arrived this statement of fact: "All life on Earth is descended from a last universal ancestor that lived approximately 3.8 billion years ago". — Preceding unsigned comment added by 50.134.168.16 (talk • contribs) 17:41, 13 October 2013

Cultural response

American philosopher Thomas Nagel wrote, “I speak from experience, being strongly subject to this fear myself: I want atheism to be true and am made uneasy by the fact that some of the most intelligent and well-informed people I know are religious believers. It isn’t just that I don’t believe in God and, naturally, hope that I’m right in my belief. It’s that I hope there is no God! I don’t want there to be a God; I don’t want the universe to be like that. My guess is that this cosmic authority problem is not a rare condition and that it is responsible for much of the scientism and reductionism of our time. One of the tendencies it supports is the ludicrous overuse of evolutionary biology to explain everything about human life, including everything about the human mind …. This is a somewhat ridiculous situation …. [I]t is just as irrational to be influenced in one’s beliefs by the hope that God does not exist as by the hope that God does exist.”

American writer Leon Wieseltier wrote, "Scientism is not the same thing as science. Science is a blessing, but scientism is a curse. Science, I mean what practicing scientists actually do, is acutely and admirably aware of its limits, and humbly admits to the provisional character of its conclusions; but scientism is dogmatic, and peddles certainties. It is always at the ready with the solution to every problem, because it believes that the solution to every problem is a scientific one, and so it gives scientific answers to non-scientific questions. Owing to its preference for totalistic explanation, scientism transforms science into an ideology, which is of course a betrayal of the experimental and empirical spirit."

This strikes me as entirely irrelevant. Who really cares what either of these people think? Especially Wieseltier. Dbrodbeck (talk) 01:07, 20 October 2013 (UTC)

Especially since Atheism and Scientism are entirely, nay, utterly irrelevant to the topic of Evolution(ary Biology), that is, when Creationists aren't trying to illegitimately and or inappropriately graft the former two into the latter in order to create strawmen turned manufactured crises of faith.--Mr Fink (talk) 01:52, 20 October 2013 (UTC)

I believe these quotes are general criticisms of a type of scientist, not science generally, and certainly not the theory of evolution specifically. There are probably articles on WP where they might be relevant.--Andrew Lancaster (talk) 09:56, 20 October 2013 (UTC)

And they may be useful in the articles on those two authors. Chiswick Chap (talk) 10:36, 20 October 2013 (UTC)

Genetic hitchhiking

I suggest to remove the section "Genetic hitchhiking". It doesn't have much to do with evolution or its relevance for evolution is not discussed sufficiently. Also, 2 of the 3 cited references are of no or only marginal relevance to the subject. The section can be moved to a genetics page where it would be perfectly appropriate (provided that the references are fixed). Peteruetz (talk) 21:04, 7 September 2013 (UTC)

I don't agree. It has a lot to do with evolution, as it has the effect that evolution increases the prevalence of certain genes not because they in themselves have survival advantages, but because they are associated with genes that do. JamesBWatson (talk) 21:52, 20 October 2013 (UTC)

Scientific response

Quote mining with no proposed article improvement
The following discussion has been closed. Please do not modify it.
British zoologist and physiologist Gerald A. Kerkut wrote, “There is a theory which states that many living animals can be observed over the course of time to undergo changes so that new species are formed. This can be called the ‘Special Theory of Evolution’ and can be demonstrated in certain cases by experiments. On the other hand there is the theory that all the living forms in the world have arisen from a single source which itself came from an inorganic form. This theory can be called the ‘General Theory of Evolution’ and the evidence that supports it is not sufficiently strong to allow us to consider it as anything more than a working hypothesis. It is not clear whether the changes that bring about speciation are of the same nature as those that brought about the development of new phyla. The answer will be found in future experimental work and not by the dogmatic assertions that the General Theory of Evolution must be correct because there is nothing else that will satisfactorily take its place.” British geologist Bernard Wood wrote,“There is a popular image of human evolution that you’ll find all over the place … On the left of the picture there’s an ape … On the right, a man … Between the two is a succession of figures that become ever more like humans … Our progress from ape to human looks so smooth, so tidy. It’s such a beguiling image that even the experts are loath to let it go. But it is an illusion.” Ian Thompson said, "Darwin’s ominous book [Origin of Species] had been available in Bronn’s translation for two years. The German professional zoologists, botanists and geologists almost all regarded it [Darwin’s theory] as absolute nonsense. Agassiz, Geibel, Keferstein, and so many others, laughed until they were red in the face –." Ian Taylor wrote, "He (German biologist Ernst Haeckel) became Darwin’s chief European apostle proclaiming the Gospel of evolution with evangelistic fervor, not only to the university intelligentsia but to the common man by popular books and to the working classes by lectures in rented halls." British astronomer Sir Fred Hoyle said, "The likelihood of the formation of life from inanimate matter is one to a number with 40,000 naughts after it ... It is big enough to bury Darwin and the whole theory of evolution. There was no primeval soup, neither on this planet nor any other, and if the beginnings of life were not random, they must therefore have been the product of purposeful intelligence.” In the 19th century, only a minority of the scientific community accepted evolution as a fact. Many favored competing explanations. By the 21st century, a broad consensus seems to have developed in support of the theory. Concerning the consensus,Michael Crichton, author of Jurassic Park, said in his lecture at California Institute of Technology: “I want to pause here and talk about this notion of consensus, and the rise of what has been called consensus science. I regard consensus science as an extremely pernicious development that ought to be stopped cold in its tracks. Historically, the claim of consensus has been the first refuge of scoundrels; it is a way to avoid debate by claiming that the matter is already settled. Whenever you hear the consensus of scientists agrees on something or other, reach for your wallet, because you’re being had. “Let’s be clear: the work of science has nothing whatever to do with consensus. Consensus is the business of politics. Science, on the contrary, requires only one investigator who happens to be right, which means that he or she has results that are verifiable by reference to the real world. In science consensus is irrelevant. What is relevant is reproducible results. The greatest scientists in history are great precisely because they broke with the consensus. “There is no such thing as consensus science. If it’s consensus, it isn’t science. If it’s science, it isn’t consensus. Period.” This looks like an ill-assorted quote mine, hatted as no evident usefulness. . dave souza, talk 08:07, 21 October 2013 (UTC)

Fact versus theory of evolution

This article omits a point that is extremely important both for understanding scientific logic and for dealing with critics of evolution--the distinction between the observable FACT of evolution (species change and common descent, no longer in the least controversial) and the theory of evolution (a constantly shifting scientific consensus about the precise interrelated roles of natural selection, mutation, genetic drift, epigenetics, group selection, exaptation, punctuated equilibrium, and so fourth). What many (and I would hazard to say most) lay people don't clearly understand is that scientific controversies over details of theory have no bearing whatsoever on the rock bottom scientific consensus on the FACT of evolution. It is a simple fact that life evolves.

Granted there is a single good sentence in the introduction referring to the fact of evolution --"Biologists agree that descent with modification is one of the most reliably established facts in science"--but most lay people would read that to mean that a key part of the theory of evolution is factually true--i.e. the fact/theory distinction is never clarified. The point is: you can have a theory about what the facts are, and a theory about what caused the facts, and they are not at all the same thing. The facts are what actually happened: descent with modification. That broad fact has become incontrovertible, so theorizing about that fact is no longer relevant to science. We do have smaller controversies about the exact course of that common descent. The explanation for the facts is even more controversial, and keeps being challenged (in relatively small ways) as a necessary part of ongoing science.

It follows, not incidentally, that evidence for the fact of evolution is distinct from evidence for particular theories of evolution. Therefore it ought to be treated separately in your article. Granted that the fact of evolution was not fully accepted until a good explanatory theory came along, nevertheless the fact of evolution was emerging into scientific understanding well before the Darwin/Wallace theory came along. I think it a serious weakness of this article that it does not make that critical distinction, and also does not clearly separate evidence for the fact from evidence for specific theories.

Also not incidentally, once that distinction is made, most of the attacks on evolution made by creationists become obviously irrelevant. Scientific controversies over details of the theory have nothing to do with the fact that species were observably not created as is some 10,000 years ago.

Response to removed paragraph

The text below in quotes, that I had inserted, was removed. It was previously removed with the comments Danielkueh (talk | contribs)‎ . . (171,960 bytes) (-1,463)‎ . . (Two issues: 1) Not too clear where editor was going with this. 2) Based on the names of the first two authors on one of the two cited sources, there appears to be WP:COI issues. Please discuss on talk page.) (undo | thank).

I apologize for doing an undo without taking it to a talk page as requested. I had not done an undo previously, and I see I was in error by not taking it to the talk page. I plan to do it properly if I see the need for an undo in the future with a request to take it to the talk page.

This is the paragraph in question: "One of the major unresolved problems in biology is the primary adaptive function of meiosis (and homologous recombination), which bears on the even larger problem of the adaptive function of sex in eukaryotes. One view is that meiosis evolved primarily as an adaptation for increasing genetic diversity. An alternative view is that meiosis is an adaptation primarily for promoting accurate DNA repair (by homologous recombination) in germ line DNA, and that increased diversity is a byproduct that may be useful in the long term. (See also Evolution of sexual reproduction)."

Issue 1 indicated "Not too clear where editor was going with this." It seemed reasonable to me to include, in an article on Evolution (subsection "Adaptation") to consider a widely recognized unresolved problem in this area, namely the adaptive function of sexual reproduction. My intent was not to discuss this issue in any detail, but rather to indicate the major alternative lines of reasoning relating to this aspect of evolution.

Issue 2 indicated "Based on the names of the first two authors on one of the two cited sources, there appears to be WP:COI issues." Although I have worked in this area, I have taken out the reference to my own work and replaced it with an independent authoritative reference to a review by Birdsell and Willis (Birdsell JA, Wills C (2003). The evolutionary origin and maintenance of sexual recombination: A review of contemporary models. Evolutionary Biology Series >> Evolutionary Biology, Vol. 33 pp. 27-137. MacIntyre, Ross J.; Clegg, Michael, T (Eds.), Springer. Hardcover ISBN 978-0306472619, ISBN 0306472619 Softcover ISBN 978-1-4419-3385-0). With respect to the citation to Horandl, 2013, my name is only mentioned as the editor of a volume titled "Meiosis" but I did not contribute to the paper by Horandl contained in this book (Elvira Hörandl (2013). Meiosis and the Paradox of Sex in Nature, Meiosis, C. Bernstein (Ed.), ISBN: 978-953-51-1197-9, InTech, DOI: 10.5772/56542. Available from: http://www.intechopen.com/books/meiosis/meiosis-and-the-paradox-of-sex-in-nature).

The paragraph that was removed is neutral and I think it is unbiased. I suggest that the paragraph be returned to the article. — Preceding unsigned comment added by Bernstein0275 (talk • contribs) 02:05, 6 November 2013 (UTC) Bernstein0275 (talk) 02:10, 6 November 2013 (UTC)

There is nothing wrong with the paragraph per se, but the content is too specialized for the general Evolution page. The evolvability sentence it follows is already at the limit of a point on adaptation belonging within a general Evolution article. The evolution of sex could go in to that sentence as an example, eg "An interesting but still controversial idea is that some adaptations, e.g. sexual reproduction, might increase the ability of organisms to generate genetic diversity and adapt by natural selection" with appropriate refs. The evolution of meiosis is simply to specialized to go within an Adaptation subsection of a more general article. Joannamasel (talk) 03:35, 6 November 2013 (UTC)

I think that's a good idea. danielkueh (talk) 23:20, 6 November 2013 (UTC)

Adaptations subsection: Addition of definitions "byproducts" and "random noise"

Suggest adding the following to include definitions for "byproducts" and "random noise," along with the following table of definitions / examples. (Note: I added this, but it was reverted. Imho, seems relevant and important to include. If the psychological examples are of concern, that row could be removed from the table.)

As noted in the table below, traits may also be byproducts of adaptations (sometimes called "spandrels"), or random variation between individuals.

	Adaptation	Exaptation	By-Product	Random Noise
Definition	Organismic trait designed to solve an ancestral problem(s). Shows complexity, special "design", functionality	Adaptation that has been "re-designed" to solve a different adaptive problem.	Byproduct of an adaptive mechanism with no current or ancestral function	Random variations in an adaptation or byproduct
Physiological Example	Bones / Umbilical cord	Small bones of the inner ear	White color of bones / Belly button	Bumps on the skull, convex or concave belly button shape
Psychological Example	Toddlers’ ability to learn to talk with minimal instruction.	Voluntary Attention	Ability to learn to read and write.	Within-sex variations in voice pitch.

One of the tasks of evolutionary biology and psychology is to identify which traits are likely to be adaptations, exaptations, byproducts or random variation. George C Williams suggested that an "adaptation is a special and onerous concept that should only be used where it is really necessary." As noted by Williams and others, adaptations can be identified by their improbable complexity, species universality, and adaptive functionality.

Memills (talk) 19:03, 11 November 2013 (UTC)

• Oppose. The section on adaptation already discusses vestigial structures and exaptations. This proposed table (much of its contents unsourced) is nothing more than a carbon copy of the one found in Evolutionary Psychology. We don't need to duplicate it in a general article on biological evolution. This table and the random quote by George Williams add nothing to this article. danielkueh (talk) 19:15, 11 November 2013 (UTC)

By-products are not necessarily vestigial structures. The table classifications, and most of the examples, are sourced to the Buss, et al. reference. The George Williams ref (from his book Adaptation and Natural Selection) identifies the criteria to be used to identify adaptations / exaptations (from byproducts / noise). Memills (talk) 19:34, 11 November 2013 (UTC)

Sorry, no. This section already gave three definitions of adaptation. It does not need a poorly formulated one from this table. This table should remain in evolutionary psychology, where it belongs. We don't need to duplicate it here. That is why we have SEPARATE WP pages. danielkueh (talk) 19:49, 11 November 2013 (UTC)

About User Slrubenstein

I know this is probably not the place to say this but because the user, Slrubenstein, was a frequent and prominent contributor to this page, I believe we can make a small exception to the talk page guidelines. For those of you who know the user:Slrubenstein or who have interacted with him in one way or another in the past but have kept up with him, I would like to point you to an important update on his personal page. I myself just learned about this today. Slrubenstein (or Steven) has been a prolific contributor on Wikipedia for quite a few years, and he has been a frequent editor of the evolution page. Anyone who has bothered to go over the archives of this talk page will see that Steven has made a lot of very important and positive contributions to this page. He will definitely be missed. danielkueh (talk) 22:39, 11 November 2013 (UTC)

Jim1138 (talk) 03:56, 10 November 2013 (UTC) Why don't scientists proclaim the Theory of Evolution the Law of Evolution? I read the FAQ. So they favor the majority over the minority? That does seem biased, not NPOV. -- Billybob2002 (talk) 04:03, 10 November 2013 (UTC) Evolution is about as much in question as gravity. You don't seem to understand what theory means. Dbrodbeck (talk) 04:07, 10 November 2013 (UTC) Just because the majority holds this view, does not mean that it should be treated as fact. Years ago, the majority held the view that the Earth was flat. It was eventually proven false. Until Evolution is proven, or proven false, it should be treated as a theory. Personally, I believe it is already proven false, but this is supposedly NPOV. -- Billybob2002 (talk) 04:27, 10 November 2013 (UTC) When scientific consensus declares Evolution has been proven false or has serious issues with it, the Wikipedia article will change to reflect that fact. I wouldn't hold my breath though. --NeilN talk to me 04:54, 10 November 2013 (UTC) Billybob, what you believe is of absolutely no consequence at all, unless you can demonstrate to other editors that your beliefs magically trump scientific consensus. And that's highly unlikely, given your use of the "escape to the future" and appeal to emotion logical fallacies and your insistence on misusing the word "theory" to mean "unsubstantiated wild guess" solely because you dislike evolution. At the very least, please understand that it is called the "theory of evolution" because it both describes the phenomenon of biological evolution and explains how and why biological evolution it occurs. It is not called "the law of evolution" because a scientific law merely describes the specific occurence of a particular natural phenomenon, and does not, according to your deliberate misuse of the term, imply that a scientific law occupies a higher hierarchical ranking than a theory. So, until you can bother to properly learn and understand elementary scientific terminology, please stop wasting everyone's time by trying to push your non-neutral point of view.--Mr Fink (talk) 07:07, 10 November 2013 (UTC) Could the header in the article be entitled "The Theory of Evolution" instead of "Evolution"? -- Billybob2002 (talk) 03:44, 14 November 2013 (UTC) The title is consistent with other articles detailing scientific theories such as as special and general relativity, quantum mechanics, plate tectonics, and gravity. --NeilN talk to me 04:00, 14 November 2013 (UTC) You know, some of the Creationism related articles have a Controversy section, so why can't the Evolution article have it? -- Billybob2002 (talk) 03:50, 14 November 2013 (UTC) Because of Wikipedia:Fringe_theories#Reporting_on_the_levels_of_acceptance. Creationism is fringe "science" (quotes intended), evolution is not. --NeilN talk to me 03:55, 14 November 2013 (UTC) Because there is no controversy. Creationism is, frankly, magic. Evolution is not. Evolution is only questioned by people who don't understand how science works. To repeat, there is no controversy. Dbrodbeck (talk) 03:58, 14 November 2013 (UTC) In your bias there is none, but it does exist. -- Billybob2002 (talk) 04:01, 14 November 2013 (UTC) And some people believe the moon landings were faked. Doesn't mean we treat their ideas credulously. Evolution#Social_and_cultural_responses meets our goal of balance. --NeilN talk to me 04:08, 14 November 2013 (UTC) I don't know what 'In your bias' means. But, the overwhelming consensus among scientists, and I mean really overwhelming is that evolution is true. Your opinion, and mine, simply don't matter. Move on. Dbrodbeck (talk) 04:16, 14 November 2013 (UTC) Billybob, there is no controversy in science about evolution. It has been observed to occur, and has been documented literally millions of times. Your opinion and assessment of evolution and science is totally irrelevant, worthless, even, given as how you have neither basic knowledge of science or scientific terminology, nor the desire to learn basic knowledge of science or scientific terminology. Your insistence that we at the very least, retitle this page to assuage your pro-Creationist, anti-science agenda is pointless, and is wearing other editors' patience thin.--Mr Fink (talk) 04:26, 14 November 2013 (UTC)

Suggested Introductory Sentence Change

I suggest changing the introductory sentence from what it is now to Evolution is "Change in the genetic composition of a population during successive generations, as a result of natural selection acting on the genetic variation among individuals, and resulting in the development of new species." I believe this a clearer definition of what Evolution actually is and reads easier.

I'd like to get a few opinions on this. — Preceding unsigned comment added by RandomEditPro (talk • contribs) 17:03, 8 October 2013 (UTC)

At the moment, nothing much that I can think of. However, there is always room for improvement. Again, I recommend going through the archives carefully. Many ideas have been forward, but few of them have actually been pursued. Perhaps you can have a look and see which areas can be improved. Alternatively, you can look at other pages on evolution (e.g., evolutionary biology) that need more improvement. Also, this page is often a target of individuals with little to no understanding of science.

I think there is insufficient evidence to make the absolute claim that "life evolved from a universal common ancestor 3.2 Billion years ago".

Your thoughts about anyone's beliefs are irrelevant, what published reliable source supports such an assessment as realistic consensus of peer reviewed science? . . dave souza, talk 08:04, 21 October 2013 (UTC)

I think the present definition is fine, but what does strike me is it seems to indicate only "change" is evolution, whereas maintenance is too-hence "living fossils". The living fossil misnomer gives people the impression they haven't evolved. It technically is the "change and maintenance" of heritable traits in successive generations of populations. Not that I think we should change the intro of article but we should make sure the distinction is made so people aren't confused. Regards GetAgrippa (talk)

Agreed with GetAgrippa. Evolution is not just change. Most species persist for 500,000 to 2 million years, some even longer. Of course change takes place in the populations, but then some parts remain the same - such as the DNA that gets passed along. The DNA doesn't change - it gets replicated and exchanged. Some of the information changes, but some of it remains stable and yet we still have evolution. Through the replication process the template is preserved. This is why heritability is so important in the evolutionary process. One of the top critiques against Darwin's original proposal was the blending of characters would create too much change for evolution to work. It was the discovery of the stasis of independent heritable traits that defeated this part of the debate. It should read:

"Evolution is the exchange of inherited characteristics in biological populations that tend to diversify and even speciate when subjected to different environmental conditions over successive generations." or "Evolution is a process of inheritance and change in the characteristics of biological populations over successive generations." — Preceding unsigned comment added by 184.71.102.86 (talk) 03:00, 21 November 2013 (UTC)

Well you don't need "different environmental conditions" either. The Lenski bacteria experiment demonstrates it occurs without any environmental necessity with changes in size and use of citrate. Great examples of exaptations in this process too. I'd leave the sentence as is, but explain what "change" means later in the text. The Lenski experiment is a great example of descent with modification. GetAgrippa (talk) 15:37, 2 December 2013 (UTC)

At what point do you separate the gene from the environment? Don't genes create their environment? If a piece of DNA mutates, then you have a different kind of environment. Seems to me (and other published geneticists) that the two are inseparable. Try to peel the two apart and tell me when you succeed. The sentence stated "tend", didn't say it was a requirement.

Thankyou for your time..Today the state of biological evolution here on Earth is "biology attracting consciousness", we can be "present to biological consciousness"...This will be my last attempt to show a place for involution and evolution at one time..once again thankyou for your time...(UTC)arnold

You haven't actually explained anything, let alone explain specifically why your definition of "Involution" belongs in "Evolution," which specifically discusses only biological evolution. Please also be aware that Wikipedia is also not the place for peddling your personal pet theories.--Mr Fink (talk) 16:46, 14 December 2013 (UTC)

Expanding the cultual and scientific response

Propose...Evolution induces Involution...through noting other "causes of evolution" by natural selection, mutation, genetic drift and today "psychology-consciousness". These two Wiki articles, should be noted in content, and compared to each other as spontaneous actualities in time.76.89.147.44 (talk) 20:29, 10 December 2013 (UTC)arnold

Not done. As it was repeatedly suggested to you before, it would be more constructive if you were to try to expand the relevant pages on Involution, rather than attempting to ask to shoehorn it into this page, where it is not a relevant topic. That, and please do not peddle your personal pet theories on the talkpages.--Mr Fink (talk) 16:46, 14 December 2013 (UTC)

Opening Sentence

I included the word "theory" (as in scientific theory) as this is how evolution has been presented in all the scientific textbooks I have read although I certainly have not read them all. If evolution is not a scientific theory, then that word should be removed from the remainder of the article. (It currently appears several times.) I think, however, that all would agree that evolution is a scientific theory. It meets the criteria of being such and is defined as such in most places. Please see http://www.britannica.com/EBchecked/topic/197367/evolution. Wpete510 (talk) 22:42, 25 November 2013 (UTC)

I suggest you read Evolution as fact and theory Theroadislong (talk) 22:48, 25 November 2013 (UTC)

Wpete510, evolution is a fact. There are plenty of mainstream scientific references that confirmed this statement. The phrase "evolution as a theory" is usually used as shorthand for evolution by means of natural selection as well for the explanation of origin of diversity, etc. I hope this clarifies the confusion. As Theroadislong suggested, the article on Evolution as fact and theory might be helpful. Regards, danielkueh (talk) 22:57, 25 November 2013 (UTC)

Thank you both for your prompt responses. I am not saying evolution is not a fact. Of course it is. That, however, does not preclude it from being a theory (even as it says in Evolution as fact and theory). We cannot escape the fact that evolution is a scientific theory. Of course it is so well-substantiated that it is a fact, but it is still a theory. The scholars who write and edit Encyclopedia Brittanica have affirmed that, so I guess I wonder why there is an objection to that term. Wpete510 (talk) 23:51, 25 November 2013 (UTC)

Natural Selection is a theory, evolution is the phenomenon. Dbrodbeck (talk) 23:52, 25 November 2013 (UTC)

The word "theory" occurs throughout the article in reference to evolution, not just natural selection. So, if that term is used improperly, someone should go through and remove it. Also, how do you account for Britannica's use of the word "theory" as the first word used to define and describe evolution? Wpete510 (talk) 23:59, 25 November 2013 (UTC)

Wpete510, three things. First, As Dbrodbeck pointed out above, there is a distinction between evolution (a fact) and evolution by means of natural selection (a theory). This article is about evolution in all instances and not just evolution by natural selection. Also, if you read the Britannica article that you gave carefully, you will notice that the article describes evolution in the two ways (the first and seventh paragraphs) that I mentioned. Second, there are plenty of sources from scientific journals and academic books that clearly describe evolution as a fact. if you go through archive #60, you'll see a list of high quality sources that support this statement. Finally, we go with the scientific consensus. The consensus at this time and very possibly to the end of time, is that evolution is a fact. Regards. danielkueh (talk) 00:09, 26 November 2013 (UTC)

Again, I do not object to calling it a fact. I know that evolution is a huge topic, and that no intelligent person in the scientific community disputes that it occurs. But, there would be many scientific theories where that is the case. Is the article in Brittanica covering a different topic than the Wikipedia article? I ask because I wonder why Brittanica would use "theory" as the very first word to define evolution, but there is apparently a strong objection to it appearing near the beginning of the Wikipedia article.Wpete510 (talk) 00:23, 26 November 2013 (UTC)

Wpete510, I cannot speak for the writers at Britannica. And quite frankly, I don't care. We stick to the policies of Wikipedia, and not to those of Britannica. Plus, the word theory is already used in the lead (third paragraph), where it fits well with the historical descriptions of Darwin and evolutionary theory. So if you are still hung up on the discrepancy in writing style between Britannica and Wikipedia (and all the other reliable sources), then perhaps you should write to their editor and ask them why don't they describe evolution the way Wikipedia does? Regards. danielkueh (talk) 00:34, 26 November 2013 (UTC)

Well, at the end of the day, I don't think anyone would hold up Wikipedia as a better source than Encyclopedia Brittanica, but I know that does not really matter. I can see I am outnumbered on the wording (at least among wikipedia editors of this article), so I can let it drop I suppose. Thank you for your interaction.Wpete510 (talk) 00:57, 26 November 2013 (UTC)

Gravitation is a fact. But it also has theories to explain the fact. Same so for evolution. We can give examples of the fact of evolution and then use theory to explain how it occurred by natural selection, genetic drift, or hybridization for example. The stickleback fish supermodel is an excellent example of this fact and theory. GetAgrippa (talk) 16:56, 28 November 2013 (UTC)

"Gravitation is a fact." Nope. Gravitation refers to fact. An apple falling is a fact that is explained through gravitational theory. What is gravity, really? It is a field, but then what is a field? Maxwell provided the initial theory development on this followed by Einstein's work, but it is all theory laden. Fact and theory remain separate for good reason. A good clue on the difference between fact and theory is the scope of the term. A specific instance of an apple falling is very simple. Gravitation is a hugely loaded word that covers a great many instances of falling apples. Same so for evolution. If theory becomes fact because it has been so tried and tested, then we step out of bounds of Popper's falsification or fallibilism.184.71.102.86 (talk) 20:38, 10 December 2013 (UTC)

Ah, a Popper chopper. In the same way that falling is a fact, evolution is a fact. Theories of evolution explain how that fact works, in the same way that various theories of gravity explain falling. Not to be confused with intelligent falling. . . dave souza, talk 20:49, 10 December 2013 (UTC)

"Popper chopper" -Nice! I am not one, but Nice! People seem to be getting the colloquial use of the term fact confused with fact as it is used in scientific logic. Fact is not what is true, but it is anything that exists independent of our imagined beliefs. Is evolution something that exists or is it something that occurs? We use scientific inference and logic to find truth, but that is what theory gives us. We can observe facts, which then become conceptions of fact as we relay them through data (statistical tables, etc). However, theory is still needed to determine the validity of a fact via a critical test. "In the same way that falling is a fact, evolution is a fact." - What is falling? The apple? What is evolving? The apple. The apple falling is the fact, gravity is the theory that explains the mechanisms and principles involved in the fall (e.g., terminal velocity). The apple falling is the fact, evolution is the theory that explains the mechanism(s) that brought the apple about in the first place. Is the apple evolving or is it a population of apples? If you want to apply this broadly and say that life is evolving is a fact, then is is also a fact that life is always evolving or that there is a tendency to evolve? The difficult thing with evolution is that we are dealing with a long time span - historical inference. You could say that single origin of life is a fact, but it is still referenced through evolutionary theory using evidence - e.g., single genetic code and understanding of "uniformitarianism" principles of replicating ancestor decendant sequence leading to an inference of homology. You can have an event that is a fact and in this way natural selection may be able to step in. It is an event - statistical like - occurring in populations. Some facts my become known through the logic of inference, but where to peel away at evolution and identify where it become fact and where it becomes theory is an impossible thing to do. It cannot be both at the same time, otherwise the scientific methodology becomes illogical. This is the general understanding that logicians have given on the scientific method[1].184.71.102.86 (talk) 21:16, 10 December 2013 (UTC)

O rly? What makes you think apples falling is a fact, or indeed that you really exist? You could be part of the Matrix, or under the matress like a troll. Which we shouldn't really feed. . . dave souza, talk 21:42, 10 December 2013 (UTC)

Because I subscribe to realism and use theory to provide an explanatory context for understanding truth and reality. The matrix is a story and I am not a solipsist. A falling apple is something that can be observed, or you can tell me that you saw an apple fall and I can decide to believe you (not too extraordinary to waste my time) or subject this to some kind of evidentual test - is the apple bruised? Calling me a troll!? - name calling is the last resort of someone who has run out of defensible reason.184.71.102.86 (talk) 00:08, 11 December 2013 (UTC)

I think this discussion is not comparing apples to apples. You can use the words theory and fact in different ways, but we should not lose sight of the fact that the aim is communication. In messy reality a thing can be described as a "fact" and a "theory" at the same time, without absurdity. That one can define meanings of those two words where it is not logical is not necessarily important or useful information.--Andrew Lancaster (talk) 21:35, 10 December 2013 (UTC)

"In messy reality" - like made up stuff? In realism, where science seems applicable - a thing CANNOT be described as a "fact" and a "theory" at the same time, unless that thing is a conception of theory, but not the theory itself as it is used in the scientific community. Does evolution fall under a different set of logic from the other sciences? I do not think you want to make this claim. If biology is using some other kind of "logic", then this is the only way in which you can use fact and theory at the same time, Other scientific disciplines have never used this approach and it is inconsistent with the philosophy as it has been understood more broadly.184.71.102.86 (talk) 21:43, 10 December 2013 (UTC)

I see that you do not define "realism" like I would. Do you say that it is important to science to avoid saying that gravity is both a fact and a theory?--Andrew Lancaster (talk) 21:51, 10 December 2013 (UTC)

Realism is a philosophy that Charles Darwin held in high standard and that is the one that I subscribe to as well. Gravity is a theory. There are alternative means that can be proposed to explain apples falling - Quantum field theory, for example.184.71.102.86 (talk) 22:20, 10 December 2013 (UTC)

Where does the graviton fit into the "fact" of gravity? This is and example of why philosophers of the scientific method have always held a strict delineation between fact and theory. The two do not mix for good logical reason.184.71.102.86 (talk) 22:26, 10 December 2013 (UTC)

Or Loop quantum gravity, or doubly special relativity, or string theory? All give different theoretical perspective on gravity. Theory referencing to fact, that's how the science of physics operates and I doubt biology has a different philosophy.184.71.102.86 (talk) 23:49, 10 December 2013 (UTC)

Effectively you are discussing your preferences concerning word definitions, and touching upon philosophical questions which Wikipedia can not solve in any final way. Such discussions can go forever. But we have used the words theory and fact because we are following the way people write about evolution in the real world, in real English, in reliable published sources. There are no god-given definitions of theory and fact to allow us do better than this. So anyway: do you have any concrete proposals for editing this article?--Andrew Lancaster (talk) 09:19, 11 December 2013 (UTC)

I am glad that you have it all sorted out and understand it well enough. I guess discussion is futile? Comment: "you are discussing your preferences"...oh really? That is a large accusation. These are not my 'preferences', it is general knowledge in the philosophy of science what fact and theory is. "we are following the way people write about evolution in the real world, in real English" - sorry for using play English. What is up with the editors in here? You try to give an honest discussion and the only way that people can find a defense is to launch personal criticism?? Is this a page about science? Can it be discussed using rational discourse? "So anyway: do you have any concrete proposals for editing this article?" - Not really, I am finished. Futile in here.184.71.102.86 (talk) 20:03, 15 December 2013 (UTC)

"Gravitation refers to the fact. An apple falling is a fact that is explained through gravitational theory." The apple falling isn't a fact-in space it wouldn't fall. The apples actions aren't significant it is the 'attractive force" that acts on the apple (we call gravity) that is the issue and the fact-it acts on everything not just apples. You aren't explaining why apples fall but what is the force that acts on the apples. The different theories refer to the force not the fall of the apple . An apple falling is explained by a fundamental force called gravity and we have numerous theories to what this force is. If all the theories prove wrong it doesn't negate the force exists we call gravity (the force is not dependent on the theory). If all of evolution theory were suddenly proven incorrect that still wouldn't negate modifications of organisms with successive generations occurs. Evolution doesn't refer to the theory-it refers to the process of descent with modification. We have theories to explain this phenomenon of descent with modification like Natural selection, genetic drift, hybridization, kin selection, etc. So you can have Evolution by Natural selection, or Evolution by Genetic drift. I know where you are coming from but I think the average reader won't understand the distinction and just add confusion. You can get into the same philosophical problems with "time" too. I think this makes sense but I have a terrible cold and my head is in a fog. Regards GetAgrippa (talk) 16:41, 11 December 2013 (UTC)

"The apple falling isn't a fact-in space it wouldn't fall."...Now we are getting somewhere! You are starting understand what the difference is. The apple falling is a fact, because it is a specific instance of an apple falling. The reason why gravity is the theory is because it explains the behaviour of the apple falling on the earth versus in space. An apple falling in space is a fact as well. It would fall - the Earth is "falling", it would just fall differently and the forces of gravity would be very weak. Gravity is the theory that explains the different facts.184.71.102.86 (talk) 19:57, 15 December 2013 (UTC)

I think you will run into problems when you qualify many science articles as theory-The theory of Evolution, The Theory of Gravitation, The Theory of the Atom, The Theory of Electromagnetism radiation, muscle contraction by the sliding filament theory, etc. An article that states white light is a theory describing the theoretical fundamental force of a specific wavelength electromagnetic radiation and it has a dual nature of particle and wave will quickly lose a reader. — Preceding unsigned comment added by 24.214.190.145 (talk • contribs) 17:35, 11 December 2013‎

In answer to GetAgrippa:

The fall of an apple is an objective fact, which we can observe. Isaac Newton invented a theory to explain the way that apples fall (amongst other things), in which he introduced the idea that the fall is due to a "force". It is now known that Newton's theory is inexact. The theory which has replaced it (general relativity) does not attribute the falling to a "force". It is thus a misunderstanding to say that "the force is not dependent on the theory": one of the two widely recognised theories uses the concept of a "force", and the other doesn't, so the "force" is very much dependent on the theory. It is also a mistake to say that "the different theories refer to the force not the fall of the apple", not only because only one of the theories refers to a "force", but also because even that theory refers not only to the force but also to the observable physical events that it sees as mediated by forces, such as the fall of an apple. The observable events are objective facts, while the mechanisms used to model them (such as forces, space-time curvature, or whatever) are theoretical constructs, and have no verifiable existence outside the theories of which they form a part. JamesBWatson (talk) 20:52, 11 December 2013 (UTC)

True a bend in space-time isn't a force but still the distinction posited will not be recognized by the average reader and will be confused. I doubt many physicist would question the "theory of the atom" no more than biologist the "theory of evolution". Explain white light as a human concept of the perception of certain wavelengths of eletromagnetic radiation is based on house of card theories. Theories about photoreceptors, theories of the dual nature of light or whatever, theories how the human brain interprets that info. We would have to qualify everything as a theory and provide evidence to substantiate each tacit. In muscle mechanics we no longer call contractility is based on the sliding filament "theory" but the siding filament mechanism of interaction of actin and myosin. I don't know what you mean by "verifiable existence" so physicist can't test their theories? So there is no verifiable existence for Black Holes? No evidence for an atom? See the confusion. GetAgrippa (talk) 23:09, 11 December 2013 (UTC)

I found this quote, which summarizes the distinction nicely:

"Over the decades as more and more was learned about evolution, many evolutionists stated that Biological Evolution was no longer a theory, but was factual or a fact (= an objective empirical observation) which confused the issue even more as a sharp difference exists between scientific theories and objective empirical observations. In most of the statements that evolution is a �scientific fact�, the author actually meant that historical evolutionary theory (= the general notion that living organisms descended with modifications from a common ancestor) is so exceedingly well tested (= well corroborated, Popper 1959; 1968: 32–34) that it can for all intense purposes be accepted as factual. However, it is still better to state that historical evolutionary theory is an exceedingly well corroborated theory and that massive counter tests supported by strong empirical objective observations are needed to disprove it. Facts, as used in science, are quite different from theories and the two are best kept strictly separated."[2]

These are not my personal views - btw. The strict philosophical distinction between fact and theory is expressed strongly in the wider literature on science. Ian Hacking, for example, has written on this as well - stating that fact and theory are separate things. To say that evolution is both fact and theory is prejudice against theory and favoritism for fact, nothing logical about it. Theory is the greatest tool that humankind has created for accessing truth about reality. Facts are simple things that most people can agree upon.

How will this help the article? Well...if it cannot be sorted out and agreed upon from the outset what evolution is, then it is not going to be very simple to write an article on it. I am certain (with supporting evidence in support of this) that evolution is a theory and it is not a fact. Common descent is a fact. Examples of natural selection in action supply facts. Fossils in different geographic localities showing relations of common decent are facts. Evolution is the theory that explains these and many other facts about biology and geology. There is a lot of confusion in this article and it may be due to this level of confusion between fact and theory.184.71.102.86 (talk) 19:57, 15 December 2013 (UTC)

Please quote a source saying something about this which is directly relevant to this article; AND/OR Please use this talk page for discussing concrete ideas which could lead to improvements of the article.--Andrew Lancaster (talk) 20:32, 15 December 2013 (UTC)

Thanks for the "education" Mr. High and mighty. Who are you to think you are in a position to give directives in an open source forum? I came in here to offer my two cents and help out on the topic, not to be lectured. "Please quote a source saying something...directly relevant to this article" - the sourced includes multiple references to the topic of evolution!! The article is about evolution. The article is about the thread of discussion. Obviously, an honest discussion is not welcomed. Your statement presents an obvious bias - re-read it and ask if your post actually does what it states. Nope, not helpful. As stated above - I am finished. I thought I would give Wikipedia a try and I was interested in this topic having studied it as my major in philosophy, but I have been called a troll, it has been stated that my contributions are 'not-concrete enough to lead to improvements', that I am expressing only my own opinions on the topic and when I provided a reference - well it isn't relevant enough to this article. That's quite a lot to take in after trying to help out only after a week. Good luck with this. Suggest that editors work on their general philosophy of civility and decorum. A huge waste of volunteer time to come in here and be personally attacked. I'll go and knock my head on a wall, more enjoyable.184.71.102.86 (talk) 22:32, 15 December 2013 (UTC)

You are taking my short post the wrong way unfortunately. We discussed more above, but my short post is pointing to the fact that in the end we have to come back to being practical on this talkpage. This talkpage is NOT a FORUM, but is meant to be used specifically for practical discussion. In fact, please see WP:NOTFORUM, which is kind of what I was thinking you would understand by my short post. The point about finding more specific evolution-related sources is that this is the Wikipedia article about evolution, and not about Popper. If experts on evolution all used terminology in a Popperian way, then this would be important to us in trying to reflect what they say, but clearly Popper's approach is not even dominant amongst experts in methodology of science. So discussion of the Popperian approach would be a major digression.--Andrew Lancaster (talk) 15:53, 17 December 2013 (UTC)

I don't have a problem and agree with your distinction between fact and theory-I've said the same thing here in the past. But it is philosophical distinction that will confuse the average reader. Further you support your posits as facts but they are opinions or theories of Popper. It gets convoluted.I think you would be best to address the Fact and Theory FAQ. You aren't the first editor to mention this distinction. It's somewhat paradoxical to say something is a "fact" and "theory" but that's where the consensus of scientist hold. I guess we would have to make clear all the criticisms of Popper ideas and mention other philosophical ideas too-so maybe this should be a separate article on the philosophy of evolution. If philosophy is your "bag" perhaps you would like to get involved an write such an article-lots of articles have sprouted from this one. I should mention that there was nothing insulting in Lancaster's comments-he was trying to be helpful to a new editor-so it seems you have an "attitude" which there is no need for such. There are some great editors here-just lost a really great one recently. Comments are welcome, but logistically articles can be so long, etc. There are rules. So new editors are welcome and comments welcome, but there is no guarantee that your contributions will be added to the article. Few of mine have. So don't give up or get perturbed-keep contributing. GetAgrippa (talk) 15:23, 17 December 2013 (UTC)

In your defense Encyclopedia Britannica states: "evolution, theory in biology postulating that the various types of plants, animals, and other living things on Earth have their origin in other preexisting types and that the distinguishable differences are due to modifications in successive generations. The theory of evolution is one of the fundamental keystones of modern biological theory." But if we examine your typical college Biology text like Campbell we find: Evolution Is Change in the Inherited Traits of a Population through Successive Generations which blends descent with modification and Mendelian genetics-population genetics and reflects the modern synthesis. No mention of "theory". The reason as I stated before while Biology is the study of life it is all based on theory-a house of cards of theories. Like note the Britannica last sentence-The theory of evolution is one of the fundamental keystones of modern biology theory. Sheesh that really says a lot. A law is consistently found to be true-a theory can't be "consistently found to be true" and is a more general explanatory statement-but when does it become too perverse to really question it -especially after over a hundred years and different supportive evidence and more importantly lots of evidence supportive of the "predictive" ability of the theory-chaotic events are unpredictable but generally it is predictive from the articles on the Darwinian possibilities of mutations to the Grants Thirty year Galapagos study where they found "evolution can be predicted in the short term from a knowledge of selection and inheritance. However, in the long term evolution is unpredictable because environments, which determine the directions and magnitudes of selection coefficients, fluctuate unpredictably.

Timeline of evolution in the lead

I think it is important to mention in the lead when evolution appeared. We can say "mid-19th" century or elaborate on when Darwin started working on evolution and when he published his work on evolution (both of which are in mid-19th). As a sidenote, common practice is to use the date that something appears in public when dating scientific work. In anycase, something must be added, the date of publication or both dates, or just "mid-19th century". Later in the lead it is mentioned when genetics is integrated to evolution (early 20th century), it is a natural maturing step for the lead to add something about when evolution started as a scientific discipline, giving a basic timeline of its development. Nxavar (talk) 18:25, 16 January 2014 (UTC)

We do state in the lead when evolution appeared on Earth, 3.8 billion years ago. As for when the concept began, the history section points to Anaximander c. 300 B.C. though arguably species fixism only really goes back to Ray in the 17th century, while Maupertuis produced early evolutionary ideas in 1751. The lead currently notes CD's contribution, of course he was made fully aware of evolutionary ideas in 1827, and started working on it in 1836, so really it's the early 19th century. But why put this in the lead? . . dave souza, talk 19:18, 16 January 2014 (UTC)

(Edit Conflict. Sorry for being redundant) Nxavar, please bear in mind that the purpose of the lead (WP:lead) is to summarize the main points of this article, which is about evolution in general and not the History of evolutionary thought or Charles Darwin, also see WP:undue. If readers would like to know more about specific dates of various publications and the development of evolutionary thought, they can go to the History section or to a decent article that covers the History of evolutionary thought. Anyway, I reverted the following sentence for two reasons:

"In the mid-19th century, Charles Darwin was the first to formulate a scientific argument for the theory of evolution by means of natural selection."

First, as Dave correctly pointed out, it is just wrong and unnecessary. Second, I don't mean to be rude, but the above sentence really looks awkward and "tacky." It has the effect of diminishing the overall prose of the lead by making the lead look like a list of bullet points: in the mid-19th century, we have this; in the 20th century, we have that. Not an improvement for an FA article. danielkueh (talk) 19:37, 16 January 2014 (UTC)

I understand your considerations. What I had in mind is that evolution is, among other things, a scientific discipline, so it would be important to know when it started. As to when it a appeared as a notion, why not mention Anaximander in the lead too? Maybe that's more important because most people think that evolution is a notion that appeared in modern history. It looks a little hard to inject this information in the lead as it is right now, maybe a small rewrite is required. Nxavar (talk) 21:54, 16 January 2014 (UTC)

Thanks, as you appreciate it's not a simple question and since this isn't the main article about the history of evolutionary thought, we don't want to go into complex detail in the lead. If you can suggest concise improvements that will be welcome. I suggest drafting wording on this talk page for discussion, . dave souza, talk 22:21, 16 January 2014 (UTC)

Nxavar, if you are looking for an article that focuses on evolution as a scientific discipline, then I would recommend that you take a look at Evolutionary biology. danielkueh (talk) 00:19, 17 January 2014 (UTC)

I checked the article on Evolutionary biology and it appears that this is narrower than evolution as a science in general. Charles Darwin is never mentioned for example and the focus is on 20th century developments. I think that here is the obvious place to put some historical context on the theory of evolution in terms of a general timeline, as far as the lead goes. What do you think about the following:

Although the notion of evolution of species has existed since ancient times, it was in the mid-19th century when the first scientific argument on the theory of evolution was introduced by Charles Darwin. He explained evolution as a process generated by natural selection, which can be inferred by observing these three facts about populations:(...)

Nxavar (talk) 05:56, 17 January 2014 (UTC)

Oppose. Evolution is not a notion and it is just simplistic to describe all pre-Darwinian ideas of evolution as "notions." Darwin was certainly not the first to propose scientific arguments for evolution (theory or fact). He was the first to propose evolution by natural selection. Pre-Darwinian arguments (e.g., Lamarck) may have been inaccurate, but they were certainly not protoscience. Other than the content, the quality of the prose is not that great as it sounds very wishy and washy. I don't want to sound like a broken record but I wish to reiterate the point that this is not the page on the history of evolutionary thought. We already have a fairly detailed historical section in this article and an entire article that is devoted to the history of evolutionary thought. Also, this article is about evolution in general and not just about evolution by natural selection. There's also a dedicated article for that. Before you devote too much energy on deciding how best to rephrase the present sentence, I think it is more fruitful to seek consensus first (WP:consensus), for these proposed changes. Without it, these changes are unlikely to go through. I also recommend that you take a look at the archives (starting with #60) of this Talk page to get a sense of the laborious group effort that went into writing the present lead. On a separate note, if you want to introduce or expand on the historical elements in the Evolutionary Biology article, you're welcome to try. That article is still very much a work in progress. danielkueh (talk) 06:37, 17 January 2014 (UTC)

Well, if the prose is of medium-quality that is not a reason in itself to oppose a contribution (unless there is some strong weekness in it). In fact the change is presented firstly here so that it can be improved upon by anyone who can. However, consensus is important, but that is still no reason to oppose! I am seeking consensus, since my first post. That's what a talk page discussion is about by default. As to whether evolution is a notion, I do not think we should get philosophical and deal with the question of what is evolution. Evolution can be many things and notion is one that the current article accepts since it is used in the History section. If you disagree with the wording "notion", propose another term. I don't see any substantial argument in your response, sorry. Nxavar (talk) 07:04, 17 January 2014 (UTC)

I opposed the proposed sentence and I have provided others reasons along with the one describing its mediocre prose. These reasons are in addition to the ones given by Dave Souza and me. You can dismiss our reasons as not being "substantial", but you are not going to get very far by pressing on with your agenda and ignoring or not addressing our concerns and the cited WP policies. With respect to the word "notion," it is used only once in this article to describe the discredited hypotheses about evolution. Finally, if you don't know what evolution is (this is not being a "philosophical", it is clearly defined in the first sentence of the lead) or think that evolution can be "many things," including "notions," then you are clearly in over your head as far as editing a science article about evolution. danielkueh (talk) 07:59, 17 January 2014 (UTC)

I'm just intrested in puting some dates nothing else. Still making irrelevant arguments so far as adding some date is concerned. I don't think there is a single Wikipedia policy against giving a starting point for the development of a scientific discipline. That's why Charles Darwin's work is mentioned in the first place. The question here is about adding dates, nothing else. Also, personal attacks are not helpful, in fact they run against Wikipedia policies. See WP:PERSONAL. Nxavar (talk) 13:07, 17 January 2014 (UTC)

The lead section is a brief summary of the article and does not need that kind of detail in it.--Charles (talk) 14:15, 17 January 2014 (UTC)

Nxavar, I am sorry if I hurt your feelings but if you don't address each of our comments or concerns, but just dismiss them as "irrelevant" or not "substantial," then you're just not going to get very far here. If you asked me to explain my comments further, I would be more than happy to do so. And I am sorry if I sounded harsh when I was responded to your other comments such as "Evolution can be many things and notion is one that the current article accepts since it is used in the History section," but I really think you need to think those statements through. If you have access to an introductory biology textbook or talk to advance high school biology instructor, you will see that there is something seriously very wrong with that statement and your proposed sentence above. In the past, we have had to protect this article against trolls who come to the talk page and insist that evolution is "just a theory," i.e. an untested hypothesis from their perspective. I am not suggesting that you are like them but it really doesn't help if we start calling evolution a "notion," assume that it can be "many things," or think we are just being "philosophical" when we define it. danielkueh (talk) 15:57, 17 January 2014 (UTC)

Yes indeed. Evolution is a natural process not a notion or any kind of man made concept. What you seem to be referring to is human understanding of the process and we have other articles which deal with that while this article is mainly about the natural process.--Charles (talk) 18:12, 17 January 2014 (UTC)

My purpose is not to present evolution as a notion. That was just wording open to discussion. The whole edit is open to discussion, and since the part refering to evolution as a notion is problematic I edited it out. The edit now just adds chronological information for Charles Darwin work, with some rewrite to make it a better read. Nxavar (talk) 21:57, 17 January 2014 (UTC)

FYI, please don't edit your proposed text after it that has been commented on. It will confuse other editors who would like to follow this discussion (see WP:REDACTED). If you wish to change it, then at least, use the strikethrough function. But a better approach would be to place another proposed text at the bottom of this thread. Thanks. danielkueh (talk) 22:32, 17 January 2014 (UTC)

I appologize, this is my first experience in this kind of discussion. I appreciate the advice. Nxavar (talk) 06:08, 18 January 2014 (UTC)

Second edit proposal:

In the mid-19th century the first scientific argument on the theory of evolution was introduced by Charles Darwin. He explained evolution as a process generated by natural selection, which can be inferred by observing these three facts about populations:(...)

Since the part refering to evolution as a notion is problematic I edited it out. The edit now just adds chronological information for Charles Darwin work, with some rewrite to make it a better read. Nxavar (talk) 06:08, 18 January 2014 (UTC)

Oppose. Factually wrong, Darwin did not introduce the first scientific argument about evolution. Evolution wasn't described as being Generated by natural selection. Also, to agree with the above, it's the wrong content for the lead of this article. I'll try and work a proposal together for alternate wording that might fit. SPACKlick (talk) 15:47, 3 February 2014 (UTC)

After reading this garbage I realize the whole article needs a rewrite and it is full of errors. Just Kidding!!!! APRIL Fools! Thought I'd strike early. A month (last post feb 3) with no activity is like some record for this article. Regards GetAgrippa (talk) 20:48, 7 March 2014 (UTC)

Incorrect sentence about speciation in the laboratory

Perhaps I misunderstand the context of the referenced article, but in the section about speciation, there is this sentence: "and the speciation process has been repeated in the laboratory, which allows the study of the genetic mechanisms involved in this process.[231]" with reference 231 pointing to this: http://www.sciencedirect.com/science/article/pii/S0959437X07001712

However, reading through the article, I cannot see where it identifies any laboratory repetition of the speciation of Arabidopsis thaliana and Arabidopsis arenosa into Arabidopsis suecica.

--Zany 001 (talk) 09:37, 9 March 2014 (UTC)

Here is an article about hybridization and speciation that was repeated in the lab. But this isn't the article I am looking for-I remember one they discovered the gene alleles that had shifted to produce the species and then mimicked the creation of the species from wild type in the lab.

Request for inclusion of external link

I work as a docent at the California Academy of Sciences and I would like to include a link to my summary of the evolution of life on Earth, which I believe is accurate according to the latest, generally accepted, scientific findings. Lottamiata (talk) 18:44, 25 April 2014 (UTC)

Just a cursory read-It ignores other theories on many topics. Further some confusion like "molten iron mantle and nickel core," The core of the earth is solid iron-nickle and the mantle is predominately solid silicates but there is the liquid outer portion. It's fine work but ignores other published data so isn't NPOV. Regards, GetAgrippa (talk) 14:25, 29 April 2014 (UTC)

Definition - where is this from ?

Can anyone recognize where the definition comes from ? The opening is "Evolution is the change in the inherited characteristics of biological populations over successive generations." without a cite. I tried google and get ... different definitions for Evolution, some similar, but not seeing source identified to some authored book or scientific society. I thought I would try here rather than just paste a cite tag on it... Markbassett (talk) 21:46, 4 June 2014 (UTC)

The lede summarizes the article and typically does not use citations. Indeed, that (the definition) is a pretty good summary of the article. Dbrodbeck (talk) 21:48, 4 June 2014 (UTC)

Thanks, view that it's an article paraphrase not externally standard definition makes sense as to why it didn't google or match authoritive locations or consistency and (ironically) that it did evolve here over time. Markbassett (talk) 16:38, 5 June 2014 (UTC)

Among other things, it is not necessary to cite the lede, as the lede's purpose is to summarize the article. Claims made in the lede do not necessarily need to be cited, either, provided they are cited in the portions of the article where they are explained in detail. Plus, it would be preferable to develop a lede that was not directly copied or lifted from another source.--Mr Fink (talk) 16:58, 5 June 2014 (UTC)

Editing Social and cultural responses

Hello to all. I added this part in the already mentioned section:

"Other authors with great authority in the field, since the end of the 19th century and the beginning of the 20th, especially the Russian zoologist and biologists who had their analysis made in the regions of Asian Russia, such as Proffesor Kessler and the prominent anarchist Peter Kropotkin are proposing more cooperative version of the theory. They are stating that Darwin and it's basic theory of evolution has been interpreted in it's most narrowest form by its best propagators, such as Julian Huxley and Herbert Spencer. Mutual struggle is accepted as one of the laws of Nature in their interpretations, but they claim that by it self it can't be the only factor of progressive evolution. "Of course", they say," 'Survival of the fittest' is the key factor of evolution, but Mutual struggle doesn't gives an answer to the question: 'Who are the fittest?'". There have been thousands of examples of mutual support and aid in all sorts of species and in every class of animals the most sociable ones are the fittest in their respective classes. As a factor of evolution, Mutual Aid is the main evolutionary factor that made humans succeed in their struggle for existence and gave them the opportunity to be the fittest and most progressive of all the species."

I was said by Physicsandwhiskey that he was not sure how this part was relevant for the subject and gave me an advice to open a discussion on this subject.

Well, here it is. My point is that it is relevant, because even then (in 19th and 20th century), but also now, there are few misconceptions about what is "evolution" and who are the "fittest" in that evolution. Mutual aid and support is totally off the list for many thinkers even today. Those ways of thinking has brought Social-Darwinism, Fascism and Nazism to it's quasi-justification. So, my point is that it's of course a cultural and social response, since it has to do everything with with culture and sociability.

I must add that I know that the concept that the 19th and early 20th century evolutionist had about evolution is way different from the modern concept of evolution, but on the macro-scale, the use of mutual-aid, as well as mutual-struggle, has helped in giving progress to most of the successful species, by which it can not be even said that it isn't scientific.

So, it is on subject, it's scientific and it has sources. I don't know in which point it is off-topic. If you have any other advice about placing that part in other subject of "evolution" which would be more appropriate, just say so.

Thanks in advance. — Preceding unsigned comment added by Rastapunk (talk • contribs) 10:27, 28 May 2014 (UTC)

Perhaps you should note that evolutionist (as you rightly said) philosophical thought of the period you mention is political, with indeed distasteful moral overtones, and has little to do with biological evolution. Chiswick Chap (talk) 10:46, 28 May 2014 (UTC)

Yes, I do know that. But the scientific fields are overlapping in this point, as I see it. And besides, the scientist here cited were all biologists and zoologist from the late 19th and early 20th century. For instance, Kessler had nothing to do with politics. On the other hand, it is our duty not just to create an encyclopedia with the thought: "Well, OK, this is the biological part - if you need something more about the philosophical, or social influence that this subject creates: check on somewhere else", but I think that it is of extreme value that we at least briefly mention the connection of biology with social, moral and political sciences, since people come here and create their own points of view and then cite wiki for every need they have. Mutual aid as a consequence of evolution is getting as low attention as it got in the 19th and 20th century and the focus is still on Mutual struggle. If you don't say anything in this subject about mutual struggle - that's not a problem, since most of the people are familiar with the connection between evolution and "the survival of the fittest", but if you don't mention mutual aid, than you are a direct associate of the creation and maintenance of "mutual struggle and nothing else" culture, which is an "everyone for his own and the Government for everyone" way of thinking. We can't say that Wikipedia has no social and political value.

Once more, you have a good point about everything you said, but I think that we do need to get out from that scope. If I can't change your mind, though, that's still OK.

Cheers,

Rastapunk (talk) 11:59, 29 May 2014 (UTC)Rastapunk

I think we must include the theory of Mutual Aid, at least for historical purposes. Even if we ignore the analogies, it does describe biological evolution and as such belongs to this article. Nxavar (talk) 18:40, 5 June 2014 (UTC)

In the second sentence of this entry the term "organization" is spelled organisation with an "s" rather than a "z". Maybe this is just a European spelling? Dtheis (talk) 04:25, 18 June 2014 (UTC)

"symbolised evolution"

A few minutes ago, I edited the caption of an image on this page from "As evolution became widely accepted in the 1870s, caricatures of Charles Darwin with an ape or monkey body symbolised evolution." to "As evolution became widely accepted in the 1870s, caricatures of Charles Darwin with an ape or monkey body were used to satirise evolution." I was reverted by User:Dave souza, with the edit summary "phrasing correct per source, see Browne". I've checked Browne's book, and I do not see how it supports the word "symbolise" as opposed to "satirise". Indeed, it specifically mentions that "the Parisian satirical journal La Petite Lune dangled him in the guise of a monkey". I would appreciate some clarification from Dave souza as to why he feels the "symbolise" wording better reflects the source. —Mr. Granger (talk · contribs) 20:04, 24 July 2014 (UTC)

Wrong cartoon, the one on the page is from The Hornet; on p. 377 Browne discusses how Darwin's beard was a bonus for cartoonists, "his general hairiness begged to be turned into animal fur. Add a tail, and there was an image that shrieked of ape or monkey ancestors". Re the Hornet image, "Such a picture of Darwin-as-ape or Darwin-as-monkey readily identified him as the author of the theory in the same way as a military longboot might have identified the Duke of Wellington". p. 378 "A hairy apish Darwin and a tree became readily recognisable images of evolution–perhaps as recognisable to Victorians as the double helix of DNA is to people today". The double helix is a symbol of genetics, and over the pages listed Browne covers how Darwin-as-ape was used in a symbolic way that didn't occur with Huxley or Wallace. The effect to a large effect promoted evolutionary ideas rather than attacking them: "Indeed this interweaving of evolutionary theory and portraits of Darwin probably contributed materially to the sense that evolutionism and Darwinism were one and the same thing." These were satirists or comedic cartoonists using a symbol, not necessarily "satirising evolution". The La Petite Lune image satirises "how Darwin's ideas were taken up by positivists" such as Auguste Comte and seems to be satirising materialist philosophy rather than evolution. A complex few pages, the point in my view is that Darwin-as-ape became as popular symbol, much appreciated by Darwin himself, rather than the attacks on evolution so familiar in the modern creation-evoution controversy. So, in my opinion "used to satirise evolution" is wrong, and misleading to a modern reader. Got any alternative suggestions for the wording? . . dave souza, talk 22:24, 24 July 2014 (UTC)

Thank you for the detailed explanation. It sounds like you're right to use "symbolise". —Mr. Granger (talk · contribs) 22:53, 24 July 2014 (UTC)

For greater clarity add "gradual" to the opening sentence changing, "Evolution is the change in the inherited characteristics of biological populations over successive generations." to "Evolution is the gradual change in the inherited characteristics of biological populations over successive generations." Dtheis (talk) 21:29, 16 July 2014 (UTC)

I'd carry out the change myself if it wasn't the WP:LEDE. I'll second the change, and back anyone who does carries it out. Ian.thomson (talk) 22:04, 16 July 2014 (UTC)

Ok, instead, if no one provides a good objection to it by the time I remember to get to it tomorrow or the next day, I'll make the change. Ian.thomson (talk) 01:34, 17 July 2014 (UTC)

I agree with both statements. Plus, I believe "gradual" supported by the provided citations and used elsewhere in the article as well. Mophedd (talk) 01:47, 17 July 2014 (UTC)

See punctuated equilibrium, but it would be a good idea to add "gradual" anyways. Evolution is most certainly gradual relative to the human lifespan, and we don't want to confuse individuals who might have the misconception that individuals can evolve. Baconfry (talk) 01:52, 17 July 2014 (UTC)

The punctuated equilibrium article has a section about the multiple meanings of "gradualism", however. Richard Dawkins (the source for much of that section) even argues that punctuated equilibrium is a form of gradualism. Mophedd (talk) 11:41, 17 July 2014 (UTC)

Done by User:Ian.thomson. —Mr. Granger (talk · contribs) 02:52, 18 July 2014 (UTC)

I've reverted the edit. Changing the definition in such a contentious article needs more discussion. You should wait longer than just one day before changing it. That gives other editors a chance to chime in. Did anyone search the talk page archives to read about previous definition consensus? What source in the article supports the "gradual" statement? Saying evolution is most certainly gradual without source confirmation is walking the OR line. In regards to punctuated equilibrium and gradualism, those are theories "in" evolutionary biology. Does that mean it applies to evolution as a whole? Do we have a source for that? Does a majority of dictionaries and textbooks use the word gradual? Thanks.Dkspartan1 (talk) 16:23, 19 July 2014 (UTC)

For what it's worth, the talk page FAQ question 5 states "Evolution, as a fact, is the gradual change in forms of life over several billion years." To be honest, it should already say "gradual", "over time", "over successive generations", or something to that effect. The point is, it takes time. There is also this [3] which says "over time", as does this [4] just to name a couple. If you need more refs, I'm more than willing to provide them. Simply reverting an edit because it's to a contentious article makes no sense, though. Was it correct? Was it concise? Would the lede still summarize the article acceptably? Thoughts? Mophedd (talk) 03:56, 20 July 2014 (UTC)

"Simply reverting an edit because it's to a contentious article makes no sense, though" That's pretty ignorant. It wasn't reverted because it's a contentious article. It was reverted because of the questions that needed to be addressed.

"it should already say "gradual", "over time", "over successive generations", or something to that effect" Are you saying you didn't see this part "change in the inherited characteristics of biological populations over successive generations"?

You didn't answer my question concerning the talk archives. If, as you claim, this should already be in the article (which it is), you don't think such an obvious omission may have been addressed before? I suggest you look at archive 64, a lot of work was done to arrive at the current definition. Dkspartan1 (talk) 09:02, 20 July 2014 (UTC)

Only reliable sources are relevant. No one cares how much work went into an article if it's unsourced or can be falsified by reliable sources. Accurate is better. I believe adding "gradual" would benefit the article (as was stated above). I tried to provide two easy sources to get the ball rolling on "gradual", or "over time". I provided a couple sources, but if you don't like them, I'm sure many more can be found (I grabbed the first 2 I saw on google as an example). The FAQ question 5 states that "Evolution, as a fact, is the gradual change in forms of life over several billion years." I believe that statement can be reliably sourced many times over. I you don't agree, either Q5 on this talk page should be under discussion, or this policy should. I read archive 64, BTW, but I didn't see suggestions for adding "gradual" directly to the lede, or really anywhere, for that matter. Since adding "gradual" is the current proposal, it can be sourced, I believe it adds greater clarity and is an improvement, I'm forced to agreed. Are you opposed to this proposal? Do you have compromise or alternative? A competing proposal? Would more sources help? There's a section and article about how evolutionary adaptations can be created within an organism's life and passed onto offspring (so called Neo-Lamarckism), flying in the face of almost all Darwinian theories. Would we be giving undue weight by mentioning this, also? Mophedd (talk) 01:50, 21 July 2014 (UTC)

Reverting the "gradual" edit is essentially saying that there's a chance that a consensus could be reached that evolution is NOT gradual. Is it possible? Instead of just bringing up how we lack sources from people who care about whether evolution is explicitly stated to be "gradual" or not, it might be better to bring up the actual argument against evolution being gradual, if that argument exists and doesn't consist of random exceptions here and there. It's like deleting a statement that says that mammals are placental because of three exceptions. Let's give the anti-gradual party another day to make their presence known, but I'm sure calling it a "gradual change" is the right way to go. Baconfry (talk) 19:45, 21 July 2014 (UTC)

Nope. If you want to add gradual, the burden is on you to support it. The sources provided don't say it's gradual. It only explains that they happen over time, which is how it's already described in the article. Dkspartan1 (talk) 21:03, 21 July 2014 (UTC)

This is a ridiculous argument, and I suggest it ends now. Are you seriously suggesting that "evolution happens over time" is in some crucial way different from "evolution is gradual"? And that the wording requires a source? Preposterous. They amount to the same thing, and you are needlessly warring about pure semantics. Correct me if I am wrong, providing appropriate citations, but no credible authority in the history of research on the topic has ever suggested that evolution happens instantaneously. Clearly that is impossible, and rational people don't need to argue the toss about it. Plantsurfer (talk) 22:32, 21 July 2014 (UTC)

Oppose addition of gradual to definition. Evolution can occur quickly or slowly. Adding gradual to the definition would no longer be accurate because we would be excluding instances that would be considered not gradual (either on a human or evolutionary timescale). Many if not most examples are slow or gradual, but it's not particularly difficult to envision bottlenecks or a trait rapidly spreading through a population if there is strong selection pressure (e.g. Peppered moth evolution). Time doesn't really play a role in what evolution is, but rather changes over generations. How fast or slow those changes happen isn't what defines evolution. Kingofaces43 (talk) 17:49, 22 July 2014 (UTC)

Oppose, as what Kingofaces said, "gradual" is extremely subjective when talking about evolution, especially when you don't specify which biological structure or taxon you're talking about, such as appearance of antibiotic resistance in bacteria versus loss of toes in horses versus trends in brachiopod evolution. If one has to add a modifier, perhaps "incremental" would be much better?--Mr Fink (talk) 18:16, 22 July 2014 (UTC)

See, that's the thing. Rate of evolution depends too much on generation time, making evolution of antibiotic resistance in bacteria considerably less gradual than in mammals. Nevertheless, evolution is still gradual enough so that you can't stare at something and watch it evolve, which is why I think it's still better to state that it's gradual. Or incremental, which I suppose also makes sense. Baconfry (talk) 16:21, 23 July 2014 (UTC)

The issue is gradual on what time scale though? Depending on who the reader is, gradual can have different meanings. That's why it seems better to keep the definition concise rather than adding terms that can muddle things.Kingofaces43 (talk) 17:06, 30 July 2014 (UTC)

Inadequate definition in the first lines

Set aside the gradual issue for a second. I find the first sentence "Evolution is the change in the inherited characteristics of biological populations over successive generations." inadequate, a pretty feeble attempt to define a momentous concept that has irreversibly altered the way mankind thinks about itself and its place in the world. That first sentence utterly fails to indicate anything at all about the nature of the change, its direction, its rate or the mechanism which brought it about or the mechanism that perpetuated it, or of its consequences. Then while we are still floundering in a miasma of doubt, before we are even introduced to the possibility that evolution is actually a process rather than just an event, we are subjected to "Evolutionary processes give rise to diversity at every level of biological organization . . .". This introduction is vague, confusing, unencyclopedic, assumes too much of the reader's background knowledge. We must be able to do better than this. We need to come up with a new form of words that nails the essential features of the concept in as few words as possible.Plantsurfer (talk) 18:11, 23 July 2014 (UTC)

Ah, there we go. Finally I can feel like I'm doing something important on this page. Here goes. "First of all, evolution itself is not the change. Change arises in genetic mutations, meiotic recombinations in crossover, and loads of other factors like transposons, viral infections, blah blah. Evolution is actually "quality control". It decides which of those random changes will be passed on to the next generation, by virtue of a simple test: all contestants are challenged to a race to see who can reproduce most successfully. Resources are not infinite. Not all of them will achieve their goal. But because the random differences between members of a population are genetic, they can be passed on through reproduction. And chances are that those mutations that made a positive difference to survival and reproduction will be the ones that make it to the next round." Now, of course, that paragraph isn't going into the article as it is. But it's my best attempt at a concise summary of what evolution really is. Did I nail it? Baconfry (talk) 18:53, 23 July 2014 (UTC)

How about starting with "Evolution is the incremental accumulations of inherited characteristics of biological populations over successive generations"?--Mr Fink (talk) 19:35, 23 July 2014 (UTC)

Accumulation?? do mammals still have the genes for fins? The possibility of loss must be accommodated also.Plantsurfer (talk) 20:02, 23 July 2014 (UTC)

Technically speaking, (a population) can accumulate and or inherit a net loss of inherited characteristics: both the acquisition and loss of biological features are characteristic changes that can be inherited by successive generations. That, and the limbs of mammals and all other tetrapods are, technically speaking either fins or heavily modified fins.--Mr Fink (talk) 21:09, 23 July 2014 (UTC)

Hairlessness is a change that can be inherited, yes?

Not in my experience, lol! Where is this going? Plantsurfer (talk) 22:26, 23 July 2014 (UTC)

Notwithstanding my feeling that the opening statements are somehow inadequate, I have to concede that it is hard to improve on them. I also note that the wording of the first sentence is, whether by accident or design, almost verbatim that of the title of this article: Forbes, A. A. & Krimmel, B. A. (2010) Evolution Is Change in the Inherited Traits of a Population through Successive Generations. Nature Education Knowledge 3(10):6. I suggest that if we are going to go with that definition it would be appropriate to cite this as a source. It would also provide a reason to fix the wording. Plantsurfer (talk) 10:24, 27 July 2014 (UTC)

Taking a step back this discussion seems to be based on the idea that we need to make evolution sound more "momentous"? Is that how scientific concepts should be explained though? I would say that the current wording did indeed come about based upon different aims, i.e. to try to distill the real facts of the matter, keeping in mind that the word is used very flexibly, and not always for momentous things.--Andrew Lancaster (talk) 16:40, 27 July 2014 (UTC)

I think part of Wikipedia is defining what a term means, many words are used in many different ways. I remember 'ethnic group' being a pretty vague term before Wikipedia was around. Everyone uses the word 'evolution' in a different way. I don't believe in 'correct' definitions so much as consistent and useful ones. I propose we adopt the following: Evolution: Umbrella term, any change over time, as stated in first sentence of article. Natural selection, horizontal gene transfer, etc... : Mechanisms which explain evolution, the observation. Theories of evolution: A theory to explain one particular facet of evolution in terms of natural history (e.g. Out of Africa Theory, Cretaceous–Paleogene extinction event) The other problem with this article is that many scientists were motivated by a desire to explain why livings things are adapted to their environment or to explain the diversity of life. As opposed to Evolution per se The Precambrian rabbit wouldn't falsify Evolution so much as discredit all of our current theories about Evolution. What do we think?

2014 New Theory of Life

“You start with a random clump of atoms, and if you shine light on it for long enough, it should not be so surprising that you get a plant,” England said. http://www.simonsfoundation.org/quanta/20140122-a-new-physics-theory-of-life/ — Preceding unsigned comment added by 91.34.196.239 (talk) 19:20, 16 July 2014 (UTC)

Let's not add that. It appears to be the misuse of a quote; the same source says that "England's theory is meant to underlie, rather than replace, Darwin's theory of evolution by natural selection", and you could've mentioned that the person's name was England. Quoting people out of context. Why am I not surprised to see this here? -Baconfry (talk) 19:26, 16 July 2014 (UTC)

Baconfry, are these just random throw-away remarks? I don't understand what you are getting at. Some of English's work, eg [5], [6] and [7], seems exceptionally interesting and relevant. It is perhaps a bit early to include it in Wikipedia, but let's see whether it holds up. --Epipelagic (talk) 20:17, 16 July 2014 (UTC)

Oops, never mind. Maybe I'm just overly sensitive, but I thought this was another example of a good scientist being quoted out of context. I don't know if it was 91.34.196.239's intention, but I'll let it go and see if we can find a place to reference England's work. -Baconfry (talk) 20:38, 16 July 2014 (UTC)

I'd be pretty surprised. Lol. Anyway it's not a mainstream theory. Not even close.Chemical Ace (talk) 13:19, 1 October 2014 (UTC)

Evolution vs. Inheritance and Breeding

Saying that changes in the frequency of genes is 'evolution' misses the point. Isnt the point of evolution that there is speciation as opposed to selective breeding? Isnt evolution still about the origin of the wide variety of species?Mrdthree (talk) 10:39, 4 October 2014 (UTC)

Al-Jahiz

He was the first person described evolution on animals. Like 1000 years ago before darwin. He must be mentioned in this article. His book "Book of animals" is a really important book in his age and even for these times.— Preceding unsigned comment added by 176.42.221.216 (talk) 02:07, 27 October 2014 (UTC)

First - new sections at the bottom of the talk page please. I have moved it there to help ease reading the talk page.

Second - in no way was he the first if he was just 1000 years before Darwin. Several ancient philosophers further than 2000 years back gave crude descriptions of evolution. Truly, the "Book of Animals" is sometimes accused of being plagiarism of Aristotle's work.Farsight001 (talk) 02:26, 27 October 2014 (UTC)

Current Thinking: Genetics In, Fossils Out?

I picked up a textbook and the arguments I grew up with for evolution have been marginalized: fossil record and comparative morphology in favor of a solely genetic definition; is this typical these days? Mrdthree (talk) 10:39, 4 October 2014 (UTC)

I think the big focus on a genetic explanation of evolution is that, in genetics, one can actually see the mechanics of evolution occurring, whereas in fossils and comparative morphology, you only see its results.--Mr Fink (talk) 13:26, 4 October 2014 (UTC)

It seems to me a genetic argument is only necessary and sufficient when evidence of speciation by altered genetics is provided. By speciation I mean establishment of a colony capable of reproducing and producing fertile offspring for potentially unlimited generations (i.e. a strain can be established that doesnt degrade like the lineage of clones). Has that sort of observation been made in the laboratory? Frankly its difficult for me to imagine that 'evolution' would be a persuasive scientific theory if discussed only as a consequence of genetics-- where would the evidence of intermediate forms come from? On the same note, which class teaches about dinosaurs or other extinct species these days? Mrdthree (talk) 07:35, 5 October 2014 (UTC)

Of course, by focusing just on the genetics aspect, that's like ignoring the forest to focus just on the trees, as fossils, comparative morphology and ecological settings show several of the forces that drive and guide evolution. And the only classes I know of that would focus on an indepth study of dinosaurs and other extinct animals (i.e., more than one class session) are classes that focus exclusively on paleontological topics. A situation that I've personally found to be rarer than hen's teeth.--Mr Fink (talk) 16:39, 5 October 2014 (UTC)

Wouldn't Archaeopteryx indicate that hen's teeth have been found in palaeontology? . . dave souza, talk 22:22, 5 October 2014 (UTC)

Being rare doesn't mean being nonexistent, especially since one can grow hen's teeth by delicately transplanting fetal mouse teeth into a chicken embryo, in addition to examining fossils of toothed avians.--Mr Fink (talk) 22:29, 5 October 2014 (UTC)

Certain geese have teeth. Like the Greylag goose has teeth on both upper and lower. GetAgrippa (talk) 18:53, 20 November 2014 (UTC)

True teeth or serrated edges of the beak, like in mergansers?--Mr Fink (talk) 19:07, 20 November 2014 (UTC)

I don't think they are true teeth because they lost the gene for enamel.But I don't think they are part of the beak-I'll check that out-been a long time. GetAgrippa (talk) 23:22, 20 November 2014 (UTC)

Well they aren't true teeth and they are just lamellae from beak. Which I should have remembered birds lost the jaw bones for teeth formation-as many other bones to lighten weight for flight. Dang getting old and losing my edge. GetAgrippa (talk) 23:30, 20 November 2014 (UTC)

"Has that sort of observation been made in the laboratory?" We are pretty close to that. Please check out E. coli long-term evolution experiment for more information.--Adam in MO Talk 05:16, 6 October 2014 (UTC)

Constructor Theory of Life

See my addition. I've read the previous physics and "philosophical" paper that is easier to digest, but I've so far only read the abstract for this newest paper. I didn't even know there were any serious doubts (now resolved?) about evolution's compatibility with quantum theory..

I thought of making Constructor theory of Life a redirect. Should it or Constructor theory be added here under See also (or in main text)? This page is locked and very important, I do want some opinions on this theory before proceding.. I'm only a physics amateur (and interested in biology). comp.arch (talk) 12:01, 26 October 2014 (UTC)

Uh, no. Can you cite oh say 50 to 100 peer reviewed articles from the biological and especially evolutionary literature that have themselves cited Constructor Theory of Life? Given the tens of thousands of articles in biology published every year, this should be an easy task... Otherwise, my appraisal is that what seems to intrigue you is probably without merit and almost certainly not significant.173.189.73.230 (talk) 21:09, 26 November 2014 (UTC)

I think there isn't enough being said here about horizontal gene transfer.

According to that Wikipedia article's lede:"... horizontal gene transfer is a highly significant phenomenon and among single-celled organisms perhaps the dominant form of genetic transfer." I think it needs to be given much more prominence here. The VAST majority of organisms on Earth are single celled. If hgt is dominant there, then it is THE dominant transfer mechanism, Q.E.D. I am not sure about the transfer of genetic information (DNA & RNA) from viruses being as significant, but clearly based on the estimates I've seen, viral genetic information comprises a significant part of our DNA and probably should also be mentioned (separately). I understand that this is a fairly "new" area of understanding, but treating Evolution, while ignoring almost completely very important genetic processes seems to be putting our heads in the sand. I'd say that epigenetic phenotype modifications (specifically methylation of DNA/gene silencing) also should be prominently mentioned because both of these things, along with germ cell mutations and somatic variation of the DNA between cells in multicellular organisms (we're all chimera) ADD to, and subtly change, the idea that what we are (genetically) is the product of (only) our parent's DNA.173.189.73.230 (talk) 21:31, 26 November 2014 (UTC)

Semi-protected edit request on 28 November 2014

Please clarify which type of evolution the author is referring to. There is speciation (which we observe) and macro-evolution (change of kinds, which is not observed). Often, writers put them together as if they are the same, but many have been confused on this issue. This change would take place upon the first two sentences in the article; perhaps it could be changed to "Evolution is of two essential definitions: speciation and macro-evolution. Speciation (which we see today) is variation within a family, while macro-evolution (not observed today) is the change from one kind of organism to another (e.g. cat to dog ... whale to cow.)." It could be something along those lines. If it is scientifically inaccurate, please don't post it, but if it is, please edit the article. 24.57.225.109 (talk) 00:43, 28 November 2014 (UTC)

Evolution and Darwin's theory of Evolution - two things.

I wonder if I might suggest a small shift of emphasis.

The 'theory of evolution' and 'Darwin's theory of evolution by natural selection' are often used as synonyms but they are really two different things. Evolution is indisputable fact, Darwin's theory is about the mechanism of evolution by natural selection: it is (slightly) less certain than evolution itself and can thus be argued against. I always try and carefully distinguish between the two lest anyone who thinks they have found a flaw in Darwin's theory think they have also found a flaw in the theory of evolution. Cassandra 2.96.13.183 (talk) 11:18, 5 December 2014 (UTC)

I think Darwin's first version, and the modern standard versions are distinguished in the article? Could you clarify what needs clarifying? You seem to emphasize a concern with the term "natural selection", but the concept of selection (which is actually a word being used metaphorically in biology) is still standard?--Andrew Lancaster (talk) 12:21, 5 December 2014 (UTC)

Article Organization

I think that the structure for the article does not allow the reader to link holistically the concepts of evolutionary theory. As an example of a better structure, I might suggest the Spanish version of the article. I would propose a new index in order to improve the organization of the article and allow for a better understanding of evolutionary theory. — Preceding unsigned comment added by 161.111.163.115 (talk) 13:12, 13 December 2014 (UTC)

I agree that the organization and clarity of this article could be improved. The Spanish version of the Evolution article does have better organization.

A Question

Shouldn't something be said about the flaws in the theory of evolution on this page to give an unbiased view of the theory?— Preceding unsigned comment added by Dogmyth (talk • contribs)

New sections belong at the bottom, please sign your posts with four tildes (~~~~). We do not give equal validity to topics which reject and are rejected by mainstream academia. For example, our article on Earth does not pretend it is flat, hollow, and/or the center of the universe. Those blue words are links to site policies and guidelines that back up the material I discuss. Given your other edits, it's clear that you're here to push a creationist POV and may not be here to build an unbiased encyclopedia. Ian.thomson (talk) 03:48, 15 December 2014 (UTC)

Additions being deleted

Okay, I do see the "NOTE: Please do not change the lead sentence(s) without consulting the discussion page first. This lead has been discussed and there is general consensus that this is the best one for now. Thanks." at the top now. Didn't notice it before... so yes, when my changes were deleted, it certainly looked like vandalism to me. I'll post my proposed changed here in the talk page, but really.... does it make ANY SENSE to have an "evolution" page, that is all about ONE KIND OF THING EVOLVING IN ONE SPECIFIC WAY, when everything capable of accumulating changes evolves? If there is a reason why my hard work should be thrown away, PLEASE , SOMEBODY, kindly explain it to me.

Here's the text of the first two paragraphs after the changes I had made...

Evolution in its broadest sense, is the accumulation of change. In this sense, anything in which changes accumulate, evolves. This is true of culture, language, computer software, technology, knowledge, automation, and so on. A quick web search for information about the evolution of any such thing should provide plenty of reference material.

Probably the most well known type of evolution, accumulation of hereditary modification, also known as descent with modification, causes the accumulation of change in the inherited characteristics of biological populations over successive generations. Such evolutionary processes give rise to diversity at every level of biological organisation, including the biodiversity of species, individual organisms and molecules such as DNA and proteins.

...There's nothing off topic about any of that, nor was it poorly written, nor was it poorly references, so why was it deleted?

This is what it is being reverted to...

Evolution is the change in the inherited characteristics of biological populations over successive generations. Evolutionary processes give rise to diversity at every level of biological organisation, including the biodiversity of species, individual organisms and molecules such as DNA and proteins.

...again, that paragraph is NOT about "evolution". It is, as I stated in my additions, about "accumulation of hereditary modification". That is a SUBSET of "evolution", and should be given its own page, if it can't be seen with an actual description of what "evolution" is. DonaldKronos (talk) 00:40, 23 December 2014 (UTC) References

Where's the evolution page belong?

Why is the evolution page for evolution in biology, or "biological evolution", rather than about the subject of evolution? Shouldn't the evolution in biology or biological evolution page be for such topics, if there is something wrong with treating them as part of the subject of evolution? Embryos evolve into babies, who evolve into children, who evolve into adults, who evolve into old people, all through the process of the accumulation of change. That is as much BIOLOGICAL evolution as evolution through descent with modification is... but I see no place for such information on that "biological evolution" page disguised as an "evolution" page. Now, how should I treat that? Can I make a suggestion? I don't even know where one would go! So I edited the page, to try to make it actually about the topic it's named after, and the response I got did not feel at all like a community treating me as a member. It felt like being attacked. So if my response to feeling like I've been attacked isn't the greatest, please forgive me.... but I have NO IDEA how to correct what I see as a MAJOR PROBLEM in that page.... especially since correcting it seems to be off limits. Should it be? Really?

I would think that a Wikipedia page about evolution should be allowed to evolve... Especially with all the damage being done out there by people claiming that evolution doesn't happen. Are we trying to make them right? I hope not.

Speaking of evolution, I had added the following short paragraph, saved the changes... somehow apparently inadvertently then deleted those same changes, and then wrote the above paragraph to replace the one below, which I thought was just lost... but turned out to be in the revision history...

It seems to me that the evolution page should be allowed to evolve. Especially considering the damage being done to human society by people claiming that evolution doesn't happen. Well... it happened, and it got reverted.

So does anyone read this? Or an I typing all of this for nothing? This whole page is like a big wall of text, and the references in the quotes I posted are showing up at the bottom... forcing the text that would OTHERWISE be at the bottom to scroll up. Is it perhaps time for wikis to evolve?

DonaldKronos (talk) 01:29, 23 December 2014 (UTC)

Many people, I imagine, have this page on their watchlist. This page is about biological evolution, as has been explained to you. Please don't take the reverts personally. Learning how things work around here can be somewhat daunting at times. Dbrodbeck (talk) 01:50, 23 December 2014 (UTC)

I'm not taking it personally. I'm taking it as an attack against humanity. Yes, it has been explained that the "evolution" page is not about "evolution" but about "biological evolution". So I added information about how "biological evolution" is a subset of "evolution" and that got deleted ALSO! DonaldKronos (talk) 04:49, 23 December 2014 (UTC)

Before you continue, DonaldKronos, please to explain explicitly how reverting, with explanations, your edits is an "attack on humanity." Last I checked, undoing a contentious edit is nothing like the other "attacks on humanity" I'm aware of, like, say, setting up and running concentration camps, flying aircraft into buildings or filling subways up with nerve gas on behalf of an insane spiritualist.--Mr Fink (talk) 05:00, 23 December 2014 (UTC)

DonaldKronos Would it not be more prudent to make a page discussing non-colloquial/broader definitions of evolution beyond biological evolution?--Mr Fink (talk) 03:14, 23 December 2014 (UTC)

Yes, it would make sense, except that there is nothing non-colloquial about "evolution". The fact that "biological evolution" is on the "evolution" page isn't bad. The fact that "evolution" is not on the "evolution" page, is ridiculous, and that "biological evolution" is not on the "biological evolution" page, is also ridiculous! DonaldKronos (talk) 04:49, 23 December 2014 (UTC)

I am being bold and making changes to the opening, including the opening sentence. My aim has been to remove dabs and thus increase and improve content, but I havent really changed any content other than to add the direct links and link to them in a way which matches the articles being linked to. And some dabs, such as dabbing the very interesting looking article on evolutionary anthropology so it appeared to link to the much less interesting, from our persepctive as readers of this article, generic article on anthropology, were misplaced IMO. We also have an intro article to make evolution simple and thus IMO dabbing say phenotype traits to characteristics was not appropriate, we would never do such a thing when explaining maths and it doesnt help our goal to educate people generally about biology to be doing this kind of dabbing. ♫ SqueakBox talk contribs 02:47, 24 December 2014 (UTC)

Thanks SqueakBox for being bold and moving this forward. Now just a few refinements. Fixing lede sentence "...modern evolutionary synthesis integrated classical genetics with Darwin's theory of evolution by natural selection...". TheProfessor (talk) 07:42, 24 December 2014 (UTC)

Another refinement for clarity of lede sentence structure: "In the mid 19th century Charles Darwin was the first to formulate an argument for the scientific theory of evolution by means of natural selection, published in his book On the Origin of Species." TheProfessor (talk) 13:57, 25 December 2014 (UTC)

Correspondence of content in body and lede

The lede of Wikipedia articles serves as an introduction and to summarize the content of the article (WP:Lede). There is a tendency to add content to the lede that is not supported in the body of the article, as the case for this recent addition:

"Although more than 99 percent of all species that ever lived on the planet are estimated to be extinct, there are currently 10—14 million species of life on the Earth. "

Drbogdan, Moxy, or others, could you help remedy this, by adding this first to the body? This could perhaps be expanded as a more complete overview of biodiversity, and then appropriately summarized in the lede. Note that citations should be body text, and are not necessary in the lede, except for cases such as controversy or quoted passages. Note this non-correspondence with the body is an issue in other parts of the lede, and needs cleaning up. Also note that various important aspects of the body are not summarized in the lede. I'm not advocating for a longer lede, just better written and following WP:MOS, perhaps even shorter once rewritten. Thanks. TheProfessor (talk) 17:19, 28 December 2014 (UTC)

Your right on all points ...perhaps to "Origin of life" section or "Natural selection"....as both the main articles mention this point in a round about way. I see that Drbogdan has added this point to a few articles so we dont have to worry the point will be missed if its not in the lead..... that said it is a very interesting fact and would be of interest to a wide audience. -- Moxy (talk) 17:38, 28 December 2014 (UTC)

FWIW - Thanks for the comments - Yes - I agree all around as well - and have no objection to adjusting and/or extending the text/refs as suggested - in any case - Thanks again for the comments - and - Enjoy! :) Drbogdan (talk) 17:47, 28 December 2014 (UTC)

Content of the lede does not currently summarize various important evolutionary concepts from the article's body. First, I propose that microevolution and macroevolution mechanisms be introduced up front, in particular natural selection and genetic variation arising from mutation, sexual reproduction and genetic recombination, and gene flow, as well as speciation, anagenesis, and extinction, with the following text in the first paragraph:

Evolution results as natural selection operates on heritable variation within a population. Variation ultimately arises from mutation, and novel variation is continually exposed by sexual reproduction, genetic recombination, and gene flow. These microevolution processes give rise to macroevolution processes of formation of new species (speciation), change within species (anagenesis), and loss of species (extinction).

TheProfessor (talk) 12:06, 31 December 2014 (UTC)

Quite frankly, in all my long years in biological science, I have never, ever heard the words "microevolution" and "macroevolution" from a fellow scientist. The term is not very much in use, and when it is used, the distinction is a lot more fuzzy and vague than you propose. The terms merely refer to evolution over shorter or longer lengths of time, whatever that may mean to the particular scientist in question.

Sorry, I don't find either of those terms useful for understanding the topic, and potentially confusing because of their widespread misuse in the fringe literature, where you often encounter absurd statements like "I believe in microevolution, but not macroevolution".

In terms of "microevolution" and "macroevolution": The term “macroevolution" was originally used in 1927 by by Russian biologist Lurii Filipchenko, and developed in contrast with "microevolution" by framers of the modern synthesis, in particular Theodosius Dobzhansky, Ernst Mayr, and George Gaylord Simpson. Mayr (1942) emphasized that "there is only a difference in degree, not in kind" between microevolution and macroevolution (as Dominus Vobisdu aptly points out above) and that “all the processes and phenomena of macroevolution and the origin of higher categories can be traced back to intraspecific variation”. Dobzhansky expounded that “there is no way towards understanding of the mechanisms of macroevolutionary changes, which require time on geologic scales, other than through an understanding of microevolutionary processes", and concluded that “‘microevolution’ and ‘macroevolution’ are relative terms and have only descriptive meaning; they imply no difference in the underlying causal agencies”. (Dobzhansky 1953). At first Simpson argued for macroevolution as a distinct process, but came into agreement with Mayr and Dozhansky. All found the distinction useful, the terms became commonly used in evolutionary biology literature and textbooks, and later evolutionary biologists still commonly use the terms (yes, in print, and in my experience, which is also extensive over many years -- reliable written sources are what matters here). I favor introducing the terms cleanly for clarity. TheProfessor (talk) 14:00, 31 December 2014 (UTC)

Note that currently microevolution is used later in the lede, while macroevolution is not. I still think that these terms should be introduced in the appropriate place, but perhaps in a sentence like this: "The terms microevolution and macroevolution, refer, respectively, to evolutionary processes over shorter time scale (natural selection, mutation, gene flow, and genetic drift) vs longer time scales (speciation, anagenesis, and extinction)." TheProfessor (talk) 16:50, 31 December 2014 (UTC)

The main point here is that the lede should introduce and summarize the article, which emphasizes evolutionary processes, and these evolutionary processes should be up front: 1) natural selection, mutation, gene flow, and genetic drift, along with heritable variation, sexual reproduction and genetic recombination; and 2) speciation, anagenesis, and extinction. What do people think about this alternative to the last sentence proposed above?

Over time these evolutionary processes lead to formation of new species (speciation), change within species (anagenesis), and loss of species (extinction).

Again, the main point of the proposed addition is to introduce and summarize the text about evolutionary processes and the importance of variation. TheProfessor (talk) 16:42, 31 December 2014 (UTC)

My objection was to using the words "microevolution" and "macroevolution". Doing so would not help the reader understand the topic any better, and would more likely confuse them into thinking that there is some difference between them rather than just the time scale. Again, the misuse of these terms by fringe proponents also gives me serious reason to avoid using the terms altogether.

Otherwise, I generally do prefer ledes to be as terse as possible, without the level of detail that you seem to prefer, especially in the form of a list of jargon terminology. However, that is a matter of editorial taste, and it wouldn't bother all that much, especially if you find support from other editors. Good luck! Dominus Vobisdu (talk) 16:55, 31 December 2014 (UTC)

Thanks Dominus Vobisdu. Your points are well taken, especially concerning fringe misuse of terms, and terse ledes. From my perspective, the organization of the article can be improved for clarity and completeness, and the lede can be rewritten accordingly. Your input is greatly appreciated. TheProfessor (talk) 17:45, 31 December 2014 (UTC)

As is yours. You're welcome. The pleasure was all mine. Good luck! Dominus Vobisdu (talk) 18:15, 31 December 2014 (UTC)

Link dabs

What is the justification for reverting the link undabbing I have been doing? Why for instance is it better to appear to link to the article on molecules rather than openly link to the article on molecular evolution. This kind of dumbing down and confusing the reader is not what dab links exist for, they excist in order to grammatically insert links. ♫ SqueakBox talk contribs 23:10, 31 December 2014 (UTC)

Hi SqueakBox. The process you call "removing unnecessary dabs" often changes the meaning or clarity of carefully crafted text. The title of related articles are often not a good substitute for what is written in the article. As explained in WP:LINK: "Appropriate links provide instant pathways to locations within and outside the project that are likely to increase readers' understanding of the topic at hand." They are not about disambiguation (dab) per se, but rather lead readers to articles that clarify or expand understanding of what is being said. The key is to choose when links should and should not be used and what prose we wish to link. Choosing to change the original language in preference for the name of the article often leads to problems, and it may be better to remove the link altogether than to change the meaning. I suggest reverting back the chosen wording of the article and reviewing the appropriateness of the links, not changing carefully crafted word choice in the article. TheProfessor (talk) 03:00, 1 January 2015 (UTC)

Ok, so I went back and restored the wording as crafted for the article. Here are some choices in terms of links: 1) "heritable trait" is a concept that is specifically used in the literature and much simpler for a reader than "heritable phenotypic trait" (which is also redundant), and a single link to the heredity or phenotypic trait page suffices in this case (both is overkill and confusing); the choice of "heritable traits" vs "heritable trait" isn't really a big deal (though I prefer the later because the term in the literature is "heritable trait"). 2) the term "biological population" is linked as "biological population" rather than "biological population" either of which is fine (though I prefer the later because again it preserves "biological population" as a term; I considered not including "biological" at all in the article, but decided this was clearest). 3) the choice of the word "molecule" is clean and clear (without extra wording "at the level of molecular evolution" just because the link would be to an article "molecular evolution"), and the best link would be molecule rather than molecule, or no link. 4) the link billion years ago adds nothing, unnecessarily diverts a reader's attention, and is therefore removed. TheProfessor (talk) 04:18, 1 January 2015 (UTC)

What are your thoughts about these two alternatives?

• Repeated formation of new species (speciation), change within species (anagenesis), and loss of species (extinction) throughout the evolutionary history of life on Earth can be inferred from shared sets of morphological and biochemical traits, including shared DNA sequences.
• Repeated formation of new species, change within a lineage, and extinction throughout the evolutionary history of life on Earth can be inferred from shared sets of morphological and biochemical traits, including shared DNA sequences.

After more thought, I think I prefer the latter for the lede, with links to technical terms in the lead (especially terms like anagenesis) and with introduction of technical terms as needed in the article body. TheProfessor (talk) 04:30, 1 January 2015 (UTC)

You need to present why your changes are better in these cases rather than quoting general policy. What is wrong with linking to phenotype? Too copmplicated? We have the intro article for simplicity. And linking an article on heredity to heredity traits confuses the reader as to the article being linked to, and for no good reason that I can see. IMO you are trying to dumb the article down which is the opposite direction from the one we should be going in. Also DNA sequencing is nott he right dab link, its an article on a science technique so why would you want to restore that error? I dont understand. ♫ SqueakBox talk contribs 06:06, 1 January 2015 (UTC)

Thanks for your effort. I'd like to reach some common ground and then put this to bed. I see improvement in the lede, and the real need is to strengthen the main article (especially organization) and then bring better correspondence between the lede and body. I didn't intend to revert your work, rather I was focusing primarily on what I was focused on crafting the prose. Yes, I favor clarity of language without "dumbing this down". Yes, I favor using rigorous terms, especially in the main article, and selectively using the most important terms in the lede. In response to your question about linking to heredity vs phenotypic trait vs phenotype (I preferred a single link that best served the main idea, and perhaps could have made a better choice, but was satisfied because phenotypic trait is in the lead sentence of heredity); this may ultimately be more about style since each article has some advantages (heredity concerns heritable phenotypic traits, phenotypic trait distinguishes heritable vs environmentally determined traits, and phenotype discusses the whole set of traits). I was trained to equate "trait" and "phenotypic trait" and prefer simplicity where possible (and that is how it used in the main article), and given that "heritable trait" is a term common in the population biology literature that is so central to the modern synthesis. As I learned it (and I can provide sources), population biologists tend to define evolution more in terms in "changes in gene frequency in a population", and the correspondence between genotype and phenotype determines what can actually be exposed to selection (also talked about in terms of degree of heritability). With respect to DNA sequencing, actually the better choice for the link may be Molecular phylogeny (which treats evolution in more detail, and yes the Nucleic acid sequence may be better than DNA sequencing). Regardless, the body of the article should take precedent, and I'd like to see more focus there. I'm ok with most of your choices. The one that bothers me the most is "heritable phenotype traits" (where I find the older version "inherited characteristics" to be better). I'd be grateful if you could examine the individual points above again, since they are not just about policy, and have basis, which may be worth understanding even if you make a different choice. For example, isn't it most important to consider the crafted language over trying to expose the name of the linked article, why not use simpler language like "molecule" (since levels and evolution are redundant here), wouldn't it be better to have fewer more relevant links, and why maintain a link to bya? Thanks again. TheProfessor (talk) 08:09, 1 January 2015 (UTC)

In terms of the lede paragraph, I'm not really so concerned about links as I am the definition of evolution. The main body of the article emphasizes genetic changes, and most sources use a definition like "change in genetic composition" or "change in gene frequency" (again the older version of the lede used "change in inherited characteristics"); "descent with modification" is also used, and can refer either to "changes in genetic composition in a population over generation" or "descent of different species from a common ancestor over generations", depending on the scale. Anyways Happy New Year! TheProfessor (talk) 18:53, 1 January 2015 (UTC)

The article needs to be consistent with other articles doesn't it? The macroevolution article states-"Macroevolution and microevolution describe fundamentally identical processes on different time scales.[1][4]" While I don't necessarily agree they are the same it is what offshoot articles states. I would add that microevolution usually involves smaller genetic changes like shifts in gene alleles while macroevolution is associated with larger chromosomal changes and genetic changes that population genetics doesn't fit.

There appears to be False balance in some important articles cf. Supernatural Creation Power. I see a clear writing style in these articles that is very easy to follow.

Evolution and Big Bang Theory are highly technical articles concerning a complex scientific subject. You may appreciate Simple Wikipedia, which was created for this very reason.   — Jess· Δ♥ 06:35, 15 February 2015 (UTC) Indeed, I shall, Puffery can be seen in first word of the second line 1)"All" certainly can have a more neutral alternative. Not so "Bright" as it were. Perhaps, It could also be all, started with "The common consensus is". 2) The line, I did not help write, "There is scientific consensus among biologists that descent with modification is one of the most reliably established of all the facts and theories in science." puts the whole subject back into theory, the statement, one of the articles truest, and most neutral, made what the fourth paragraph? cf. Truth line 2. The observation I am making is that "understanding the opposite of a thing can be very useful when understanding the reality of a thing." I.E. the theorized opposite of Evolution, Theistic Creation, is not a notion in this article, though exceedingly discussed scholarly & scientifically, even today. I am not suggesting silence.

Otherwise, you might benefit from taking some formal courses, maybe at a local college. You might find them interesting. Isambard Kingdom (talk) 08:01, 15 February 2015 (UTC) I'd also suggest reading WP:NPOV, since you referenced it. "Neutral" does not mean giving all sides equal weight; it means representing significant viewpoints in proportion to their prominence in reliable sources. Do you have any reliable sources from within the scientific community indicating that any of the sentences you've disputed are incorrect? Because we have a great deal of reliable sources indicating they are not. We cannot change the article without sources.   — Jess· Δ♥ 09:07, 15 February 2015 (UTC) Ad hominem is unnecessary and rude. And as this article clearly uses multiple definitions of the word, evolution, I propose those definitions and their differences be spelled out clearly. Again I am talking about Plain English here, I am no biologists, though my ability to read is highly evolved cf. Truth, I do agree, things change over time, or evolve, not only in biology but in every science, but this article seems to have, that science, confused with the exo nihilism fish to frog leap of faith. --Kaptinavenger (talk) 16:05, 15 February 2015 (UTC) Repeating for your highly evolved reading ability: We strive to be precise here so that necessitates using some scientific terminology.

Another kind of Evolutionary Biology, hypothesizes the changes we can see and measure, in the variation of species, is sufficient change to account for the variations in all forms of life. Both, very scientific and technical ideas with expansive areas of study, including but not limited to Paleontology Biology and Physics. I could list a bunch of science journal articles on the debate, but as I am not meaning to change the science of the things, nor the truth of them, simply saying, Wikipedia should not give weight to ideas to help prop them up, even if it is hilarious when people believe it cf. Flat Earth. --Kaptinavenger (talk) 16:40, 15 February 2015 (UTC) The alleged "opposite" of biological evolution, which you claim is Creationism, has not been studied scientifically for literal centuries when it became blatantly apparent that there literally is no evidence of God going around magically poofing organisms into existence.

Man, its dangerous, surely you can understand why, Believed to be, Well thought, Widely understood, common acceptance is that, well taught science shows, would be considered more Gentle words. You do sound rather like "You don't mean round the world, it is impossible!", I don't mean to insult though, you see many respectable people have been, wrong. That's ok, I am wrong often, that's ok. I am not proposing deleting anything from the article, the line number two should get a better handle, or intro, or easier opening, especially as it is in the beginning of the Introduction. Also, the opposite of evolve or evolution is not creation nor manufacturing (creation experienced in reality) as you would suggest, but rather devolve or devolution, the loss of complexity, sometimes towards order, although not always, over a period of time. I have mentioned other suggestions please read above comments. I do rather like the word, stilts. I suggest this article put in a couple well placed stilts so that it can get up out of the WP:PEA. & :@Mann jess:, again, I do not mean to delete anything, or change the content more than ad a smooth intro phrase. The Dictionary, can offer the opposite of evolve, and most can be cited on here right? and again just on line two the word All may be a quote or direct citation in case I suggest we ad who says first, or if it is, as it apperars, WP:PEA, I suggest we use more of the discipline that is shown in the Origin of Life section on this article, and perhaps think to offer at least the definition of devolution to the article. --Kaptinavenger (talk) 01:17, 16 February 2015 (UTC) Anyone uninvolved want to close this discussion as Kaptinavenger clearly doesn't know what we mean by reliable sources? --NeilN talk to me 01:37, 16 February 2015 (UTC)

Suggestion for Improved Accuracy

Protracted WP:IDIDNTHEARTHAT
The following discussion has been closed. Please do not modify it.
I'm suggesting the following change, simply for the sake of improving the accuracy of the page's opening statement. Where is now says... Evolution is the change in heritable phenotype traits of biological populations over successive generations. I suggest it be changed to say... In the context of biology, evolution is the change in heritable phenotype traits of biological populations over successive generations. My reasoning is that even though it is stated that this page is about evolution in biology many people coming to the page will have found it by searching for evolution and will read that opening statement without having read the italicized qualifier above it. Discussion? DonaldKronos (talk) 23:58, 31 December 2014 (UTC) Pretty much no. The overwhelming majority of readers who type in evolution expect to end up here, and those few who don't have the hatnote to steer them where they want to go. I'm hardly convinced that there are enough readers left to justify your proposed edit, which is clumsy. Basically, I think your overestimating any possible inconvenience that may occur. Also, we are not a dictionary. Our articles are about concepts, not about words. Or at least that is the plan. Dominus Vobisdu (talk) 01:05, 1 January 2015 (UTC) DonaldKronos, you've already made this suggestion. And it's already been explained to you, repeatedly, that this article is about biological evolution, only, and that all other definitions of the word "evolution" are mentioned and discussed in the disambiguation page.--Mr Fink (talk) 03:28, 1 January 2015 (UTC) Apokryltaros AKA Mr Fink I think you missed my point. I know the evolution article is about biological evolution but it is still a false claim to say that Evolution is all about biological change, and misleading anyone is an unethical and counterproductive thing to do. The change I am recommending would not detract from the subject of biological evolution in any way, and would in fact give additional information about that subject. Thanks for your feedback DonaldKronos (talk) 04:04, 1 January 2015 (UTC) Dominus Vobisdu If you feel that my rewording is clumsy, feel free to suggest a more elegant way of making the line more accurate and more considerate of those people who look up evolution expecting to find simple information about evolution such as whether it is a broad topic or a narrow one. As it stands right now, the disambiguation page has a simularly misleading line even closer to the very start of the page, so if someone is in a hurry they could easily end up drawing the quick conclusion that Wikipedia portrays the subject of evolution as restricted to the field of biology. Here's an alternative, perhaps less clumsy version to consider... --- In biology, evolution is the change in heritable phenotype traits of populations over successive generations. --- Again, if you have a better suggestion, please feel free to toss it out there, or try making your less clumsy improvement and see whether it gets left that way. I'm just trying to help. Thanks for the feedback. DonaldKronos (talk) 04:36, 1 January 2015 (UTC) I honestly don't think that any such improvement is needed, and have already explained why I don't. I think you're worrying about something that is, at worst, at very tiny problem. There are much bigger fish to fry. This is only a guppy. Dominus Vobisdu (talk) 08:43, 1 January 2015 (UTC) Here's a link to an article in Nature which supports the point I am trying to make... http://www.nature.com/news/does-evolutionary-theory-need-a-rethink-1.16080 To fully understand biological evolution, it is necessary to understand evolution. DonaldKronos (talk) 10:15, 13 January 2015 (UTC) Well Kronos technically does have a valid point as I mentioned above. Actually the word evolution predates Darwin's use of it." So what we find is that word evolution originated from Latin word evolutio, which means unrolling, something like unrolling of the scroll, and the word existed a couple of centuries before Darwin wrote Origin of Species. He infact did not even use the word evolution in his book until the last line which was: There is grandeur in this view of life, with its several powers, having been originally breathed by the Creator into a few forms or into one; and that, whilst this planet has gone circling on according to the fixed law of gravity, from so simple a beginning endless forms most beautiful and most wonderful have been, and are being evolved." Darwin in fact disliked the word "evolution" and it was his peers that made it popular. RegardsGetAgrippa (talk) 05:32, 7 February 2015 (UTC) Darwin is only a part of the history of evolutionary theory and not really central to modern terminology. ldvhl (talk) 13:02, 7 February 2015 (UTC) A small point. The article that Donald linked does not only show his point. It shows the opposite point as well. But I think donald either did not read that, or donald ignored it. Either way wikipedia is not here to settle disputes. We wait for what the scientist says. Until then nothing will change. And even then I think WP:Commonname would still be in effect even then. Which is when people think about evolution its about biological evolution and not something else.NathanWubs (talk) 15:32, 7 February 2015 (UTC) No, NathanWubs, I didn't ignore the fact that evolution comes in both biological and non-biologival types. Just as "rectangle" comes in both "square" and "non-square"types. To define "evolution" as "non-biological evolution" is no different than to define "rectangle" as "non-square rectangle", or "animal" as meaning "non-human animal". Any of those would simply be special_pleading Likewise, to define "evolution" as "biological evolution" is no different than to define "rectangle" as "square rectangle", or "animal" as meaning "human animal". Just because one type of something is the most well known types, does not mean that all other types should be discluded from the definition. DonaldKronos (talk) 19:11, 24 February 2015 (UTC) I wasn't arguing to add his additions. Just pointing out how the word gained popularity with Darwin's theory of natural selection. This is an encyclopedia and the disambiguation deals with it. Most people going to an encyclopedic article on "Evolution" will be looking for an article like this. The article he points isn't a new posit-it's been entertained before mentioning Lamb, Jablonka, etc and epigenetic notions of evolution. Regards GetAgrippa (talk) 00:11, 8 February 2015 (UTC) I think that we should add some sort of clarification to the lead sentence. Adding "In biology," to the beginning is not a bad idea. After all, modern terminology evolves and we have started to use evolution to describe other things outside of the biology field as well. For example, we may talk about the evolution of technology, or the evolution of the English language. Other encyclopedias, such as Britannica, have some sort of clarification, too. Thanks, Tony Tan98 · talk 02:41, 20 February 2015 (UTC) Per WP:NOTDICT and other guidelines, this article is about the subject, not about the word which refers to the subject. We disambiguate via disambiguation pages, and hatnotes that lead to those pages, not generally by changing our article to reflect usage of a word in other contexts. Britanica may handle this differently than we do, but that's how we do it. I'm not sure adding extra words to the lead sentence helps make this subject easier to understand.   — Jess· Δ♥ 03:06, 20 February 2015 (UTC) It is an improper treatment of the subject of biological evolution to treat it, as this article does, as if it is not a subset of the subject of evolution but rather is the embodiment of that much larger subject.... which to my knowledge still has no page on Wikipedia to represent it, since the evolution page is NOT about evolution but rather about biological evolution specifically. DonaldKronos (talk) 19:11, 24 February 2015 (UTC) There is no policy reason not to put disambiguating explanations into a lead. If such a thing helps relieve valid concerns and end a silly discussion, it should be done IMHO. Not saying it needs to be done, just saying that there is no policy reason not to do it. This article is indeed about biological evolution, but indeed the word as used has more general meanings. Both things are true, and we should not need debates about either. Explaining that the more general meaning might potentially also help explain biological evolution, and explaining is the ultimate aim above all other aims here. That is how we should be discussing. Would it help avoid misunderstandings or not? I do not understand why such disambiguation issues cause such strange discussions on Wikipedia, but I do not believe there is any real policy which is telling us we may not do anything like disambiguating within lead texts.--Andrew Lancaster (talk) 19:58, 24 February 2015 (UTC) That's exactly what I was thinking Andrew Lancaster, but unfortunately certain people seem to be highly against simply clarifying such a thing so directly. So, I have attempted a compromise. Please have a look at it. Instead of placing the clarification in the opening statement, I placed it in the text telling where to find the disambiguation page. Hopefully this solution will be acceptable. DonaldKronos (talk) 08:43, 26 February 2015 (UTC) I also added context clarification to the definition on the disambiguation page, in order to make the definition an honest one. DonaldKronos (talk) 08:53, 26 February 2015 (UTC) I see no policy reason that we can not say "in biology" in an opening line. I can not really understand why people are so opposed to it.--Andrew Lancaster (talk) 09:27, 26 February 2015 (UTC) It appears that there is a continuing campaign to solve a non-problem. In this case the "solution" in effect adds redundancy, and disambiguation has already been well addressed. Again, the hatnote clearly states up front "This article is about evolution in biology" and "For other uses, see Evolution (disambiguation)". The disambiguation page itself clearly lists biological and non-biological uses of the term. This is in no way a case of "improved accuracy", nor is it a case of "honesty", "dishonesty", or any other inappropriate label that implies some sort of untoward behaviour, plot, or lack of understanding. This has been discussed at length; discussion earlier on was considered incivil, tendentious, and disruptive, resulting in being temporarily blocked; and repeated attempts to proceed with changes have not gained support. TheProfessor (talk) 15:09, 26 February 2015 (UTC) No TheProfessor, it is not redundant to point out that a definition passed off as one thing represents something else. What I do not understand is why it's okay to specify that evolution only applies to biological organisms, which is a FALSE STATEMENT, but somehow NOT okay to point out that such a definition is not a definition of evolution but rather a definition of biological evolution. Both here and on the disambiguation page, dishonesty prevails. DonaldKronos (talk) 04:29, 27 February 2015 (UTC) There is no problem to resolve, we ought to move on. Dbrodbeck (talk) 04:33, 27 February 2015 (UTC) Good grief the whole idea of a disambiguation is to address your concern. Like "Light" can refer to "light" part of electromagnetic spectrum, Light-a common name or place, reference to calories, reference to weight.. Type in "light" and you get the physics electromagnetic/photon description of "light", but it isn't deceptive nor negate the other applications of the word. If you go to another encyclopedia it will default to physics or list all the applications-a disambiguation page. GetAgrippa (talk) 15:22, 27 February 2015 (UTC) I think User:TheProfessor's post above is bullying and disruptive, and not on topic. I see no clear policy reason why this proposal can not be made, and certainly no reason to be threatening editors with being blocked from editing? If there is something policy-wise wrong with the proposal let's just say it clearly, without referring to policies which do not exist. If it is just a personal preference, that is also valid and just say so. The proposal itself has a clear and simple logic and is not horrifying in anyway I can see.--Andrew Lancaster (talk) 16:42, 27 February 2015 (UTC) Andrew Lancaster Thanks. DonaldKronos (talk) 20:34, 27 February 2015 (UTC) GetAgrippa Exactly. The disambiguation page for light starts out by saying Light is an electromagnetic radiation, part of which stimulates the sense of vision. Even though the main light page is about visible light and not about light in general, there is no attempt made in the definition to deny that non-visible light exists or is considered to be light. It is HONEST, unlike the evolution page and it's disambiguation page insisting at the start that evolution is strictly a biological event. DonaldKronos (talk) 20:34, 27 February 2015 (UTC) So, therefore, that makes it an evil, terrible, horrible, no-good, evil conspiracy of a catastrophe in which billions will die? I mean, you are aware that your concerns have already been addressed a long time ago in the disambiguation page, and that your dire portents and dyphemisms grate away at other editors' patience with you, right?--Mr Fink (talk) 00:20, 28 February 2015 (UTC) Biological evolution, and the different forms of non-biological evolution are all unrelated concepts that merely share the same name. There is no overarching platonic ideal of Evolution of which biological evolution and the various non-biological evolutions are subsets thereof (and I say this as someone influenced by Teilhard de Chardin). Evolution, when unspecified and given no other context, usually refers to biological evolution, and so that can be considered the default. To treat the different kinds of evolutions as part of the same overall process is to completely confuse the matter to the point of imitating the YEC stereotype of "evolutionism" (again, I'm saying this as someone who was influenced by a theologian who considered various kinds of evolution to be the universe being redeemed by God). Ian.thomson (talk) 00:41, 28 February 2015 (UTC) Evolution, biological or otherwise, is the process of accumulating or rolling out change. It has been since the inception of the concept and the terminology to describe it. Claims that biological evolution and non-biological evolution share nothing more than a name in common are misguided at best. As for the straw-man argument that I'm supposedly claiming some "evil, terrible, horrible, no-good, evil conspiracy of a catastrophe in which billions will die", it's certainly nothing I have said or implied. Yes, I am aware that many times this issue has been addressed, and then reverted back to being dishonest. Evolution is not "the change in heritable phenotype traits of biological populations over successive generations." That's one narrow facet of evolution, and nothing more. It should not be passed off as a definition of evolution. Evolution is also not " the change in heritable traits of biological organisms over successive generations due to natural selection and other mechanisms." Again, that is nothing more than a narrow facet of evolution, and should not be passed off as a definition of evolution when it would be very easy to label what is being defined honestly instead. 01:45, 28 February 2015 (UTC)— Preceding unsigned comment added by DonaldKronos (talk • contribs) Your continued use of the term "honest" to refer to your preferred (and regularly unsourced) definition implies dishonesty on the part of those who disagree with you -- an utter failure of WP:AGF, if not a preemptive attack on those who do not agree with you. The accumulation of changes is the definition for the word evolution, it is not some cosmic concept for which different types of changes are subsets of. That is, Software evolution, Grammatical evolution, Spiritual evolution, Sociocultural evolution, and biological evolution are fairly distinct concepts that concern completely different things changing in completely different ways for completely different reasons over time. They are not all bound together and guided by some God of evolution, they are distinct types of unrelated chaos. About the only way they begin to relate is that some of their changes would occur in parallel as a result of their environments changing (particularly grammatical and sociocultural evolutions). Ian.thomson (talk) 01:57, 28 February 2015 (UTC) DonaldKronos, I wasn't making a strawman, I was being facetious in an obviously vain attempt to clue you in that everyone is tired of your tediously protracted sanctimony where you wail and rail about being the only honest editor while attacking everyone who won't kowtow to your proposals as being evil and dishonest conspirators conspiring against you. That, and as Ian eloquently pointed out, the different "varieties" of Evolution are totally unrelated phenomena, and that the changes you want done have already been done on the disambiguation page, and that, most importantly, you have yet to present a convincing argument to turn this page into an overarching discussion of all forms of evolution, and shuttle the contents of this page into a separate page.--Mr Fink (talk) 02:19, 28 February 2015 (UTC) Unsourced? No. Source references were deleted, like nearly everything else that point to the fact that evolution is not restricted to biology, and there is a distinction between the process of evolution in general and the much more narrow and more easily obscured subject of the process of biological evolution specifically. I'm not the one trying to hide anything here. Want a source? How about this one... [[8]] If that's not good enough, let me know. I can find hundreds pretty easily. I'm just tired of even dealing with this. I get attacked constantly in here for simply asking that a definition of biological evolution not be passed off as a definition of evolution without regard to context. DonaldKronos (talk) 04:20, 28 February 2015 (UTC) Those sources you refer to consisted of interpretation of sources beyond what they say, (original research), to make points not made in any single source (synthesis). You specifically need a source that refers to the different evolutions as being part of some unified evolutionary force. The latest source you provide, if anything, affirms that evolution usually refers to biological evolution, and that many of the non-biological forms are only called evolution because they are imitative parallels, though still distinct processes. "I'm not the one trying to hide anything here" -- NO ONE IS HIDING ANYTHING HERE, so you can either: drop that sanctimonious paranoia and assume good faith -or- leave Please provide evidence that you have been attacked. Editors pointing out that you fail to assume good faith, appear to be confused as to the topic, or not seeing any use in your suggestions are not the same as attacks -- please point out where we have commented on you as a person, not just pointing to actions that we are not pleased with. We're getting pretty tired of you dealing with this too, Donald. Ian.thomson (talk) 04:38, 28 February 2015 (UTC) Yeah, it's obvious that honesty is not wanted here. Assume good faith? I've done that. What I've watched happen disagrees with that assumption. Look up the etymology and history of the word evolution. Its broad usage has basically not changed. As for restricting it to biological evolution all I have asked is that if that's going to be done, it should be labeled as such. I even tried labeling it with a single word, so that it would not take up much space, and did nothing more that clarify that the definition given is not a broad definition, but a narrow one which applies specifically to biological evolution. Don't tell me that nothing is being hidden, when I can find no way of presenting this simple fact without it being swiftly deleted. Of course I know not everyone is in on it. Several people have even spoken up agreeing with me, but I can understand why they are so reluctant to do such a thing in this aggressively hostile environment. Where is the assumption of my good faith? Where is the attempt to find an acceptable way to correct what I have pointed out may further deceive people who have already been deceived? Why are people who agree with me generally ignored? I don't see any of the people who attack my position asking such people for advice on how some common ground might be found. Not a very democratic process from what I can see, but I am trying to encourage it to evolve. Perhaps that's too much to ask for, since it's not biological, and those who are causing its stagnation seem convinced that non-biological evolution either does not occur, or is not evolution at all, or is simply not important. DonaldKronos (talk) 05:01, 28 February 2015 (UTC) I've assumed good faith with you, I just haven't assumed competence, and your regular accusations of censorship and deception show that you are not assuming good faith. Either you are lying when you say you are, or you're just not capable of assuming good faith. The hostility you've experienced is a result of you refusing to assume good faith from anyone who didn't give you what you wanted. If you had come here interested in collaboration, you would not have started off accusing those who reverted you of vandalism, and you would not continue your accusations of deception. If you had come here interested in collaboration, you would have calmly asked editors who reverted you why they reverted, and tried to adjust your plans to fit their explanation or else try to find a broader consensus. It took you a block to pull that off. You didn't do that. Instead, you consistantly threw tantrums and made insulting allegations about others. Ian.thomson (talk) 05:08, 28 February 2015 (UTC) @DonaldKronos: you clearly do not understand that Wikipedia is a collaborative project. You repeatedly demonstrate that you have no assumption of good faith by doing things like making blatantly false accusations, i.e., by blatantly lying about how people allegedly want this article to "stagnate" because they are magically ignoring non-biological evolution, or by accusing Wikipedia of being an evil tyranny because people fail to be swayed by your tedious sanctimony and protracted temper tantrums.--Mr Fink (talk) 05:29, 28 February 2015 (UTC) I'm quite willing to let this go and assume good faith, if I can see someone other than myself attempting to discuss this here rather than trying to censor it. Please, anyone who disagrees with me, take the first step positive toward seeing if I might have a point after all. Yes, I am burnt out and having a hard time addressing this in as civilized of a manor as I should, so please... ask for people who agree with me to speak up. Hear them out. Let them talk with each other and attempt to find a solution that those who disagree with me can live with. I know I'm not the only person here who sees a problem with passing off a definition of biological evolution as a definition of evolution and not even noting in that definition "within the context of biology" or anything of the sort. I have watched other people speak up about this on many occasions, for the most part timidly and reluctantly, and quickly shot down as if they had said something wrong. Would some good person please invite them to speak up without feeling threatened? I'm okay with standing back and letting others discuss this. What I'm not okay with is being repeatedly told that I need to assume good faith when I am seeing just the opposite. So.... please? Can I assume good faith and see some evidence that it wasn't an error to do so? DonaldKronos (talk) 05:26, 28 February 2015 (UTC) Hearing people out is a two-way road, not a one-way road going only to you. If you were interested in heading down that road, you would not have made the straw-man argument that we're trying to present non-biological evolution as not evolving. There are obviously accumulated changes (hence "evolution"), but the mechanisms for them are independent from biological evolution. There just isn't a unified force connecting biological evolution with the non-biological evolutions, they just share a name. And you're still not assuming good faith. If you were, you wouldn't have implied that others are trying to censor the article. Ian.thomson (talk) 05:33, 28 February 2015 (UTC) DonaldKronos, Have you tried not accusing other editors of being liars or censorers, or evil conspirators solely because they don't agree with you or have failed to be persuaded by your endless sanctimony, or repeatedly tell you that your concerns have already been addressed a long, long time ago in Evolution (disambiguation)?--Mr Fink (talk) 05:36, 28 February 2015 (UTC)

Regarding recent changes

These edits have been reverted by multiple users because "This article is specific to evolution in biology", and the edit "appears contentious".

This article's content is about biological evolution, and (per WP:LEDE) the intro summarizes the article. The removed content discussed a number of uses of the word "evolution" that had nothing to do with biology. Ian.thomson (talk) 00:27, 23 December 2014 (UTC)

Yes, that page is about "biologcal evolution" and the biological evolution page REDIRECTS there! Why? That makes NO SENSE! The page is named "evolution". Not "biological evolution". Where should "evolution" be described, if the "evolution" page is to be RESERVED FOR "biological evolution" while the "biological evolution" page is left blank except for a redirect to the "evolution" page? In my opinion, that is HIDING WHAT EVOLUTION IS from the public. Is that what Wikipedia is for? To deceive the public? DonaldKronos (talk) 00:49, 23 December 2014 (UTC)

Per the scholarly and technical definition of the word evolution, evolution IS just biological evolution. Only colloquially does it refer to other forms of change. And since this is an encyclopedia, there is a natural preference for using terms in a scholarly/technical way, hence the evolution article is about biological evolution only. Other encyclopedias do it the exact same way.01:03, 23 December 2014 (UTC)

Actually the word predates Darwin's use of it." So what we find is that word evolution originated from Latin word evolutio, which means unrolling, something like unrolling of the scroll, and the word existed a couple of centuries before Darwin wrote Origin of Species. He infact did not even use the word evolution in his book until the last line which was: There is grandeur in this view of life, with its several powers, having been originally breathed by the Creator into a few forms or into one; and that, whilst this planet has gone circling on according to the fixed law of gravity, from so simple a beginning endless forms most beautiful and most wonderful have been, and are being evolved." Darwin in fact disliked the word "evolution" and it was his peers that made it popular. Regards GetAgrippa (talk) 05:29, 7 February 2015 (UTC)

Quote: "evolution IS just biological evolution" -- Response: Bull SH*T! BIOLOGICAL EVOLUTION is "just biological evolution". EVOLUTION is not! What religion told you that silly lie? I'm really SICK AND TIRED OF THE CENSORSHIP IN HERE! I have noticed that the article is written as if it were meant to discredit evolution, rather than to explain it. Now, should I continue trying to assume good intentions? DonaldKronos (talk) 01:49, 23 December 2014 (UTC)

My scientific education told me that. My love of words that is so extensive that I read the dictionary told me that. Other encyclopedias tell me that. Other scientific experts tell me that. And I find it strange that you think this article is written to discredit evolution. Most of the time, we get people claiming its too pro-evolution.

Now please, WP:ASSUMEGOODFAITH. Its a rule, not a recommendation. (which is exactly why you should continue trying to assume good intentions) I highly recommend abiding by it. Failure to do so generally leads to getting your account and perhaps even your IP address blocked.Farsight001 (talk) 01:57, 23 December 2014 (UTC)

You seem to have a fundamental lack of understanding that this is an encyclopedia, not a dictionary. Evolution, in this context, refers to biological evolution, not all possible applications of the term. Your posts continue to be insulting and rude, while ignoring all feedback you receive. Zarcusian (talk) 01:54, 23 December 2014 (UTC)

I have reported DonaldKronos for edit warring. I'd've been more willing to look the other way if he hadn't been completely hostile to everyone he's interacted with. Ian.thomson (talk) 03:10, 23 December 2014 (UTC)

Hello Ian.thomson. Sorry what I was doing came off as "edit warring". That was not my intention. I simply had no idea how to contact people in here... nor at first even how to find this talk page (nor did I think to look for it at first). I'm not entirely unfamiliar with editing in Wikipedia, but unfortunately I had in the past had similar experiences and could not find anyone to tell me what I most needed to know.... how to reply to people. Needless to say, the frustration was overwhelming. Please accept my apology.

Sorry Zarcusian. I was banned, and unable to reply, before I was able to figure out (thanks to some helpful people) how to actually post a reply. It's not as intuitive before learning it as it seems AFTER learning it. LOL!.

I had not meant to call you a vandal. I over-reacted due mainly to previous bad experiences in Wikipedia. How biological evolution fits into the broader concept of evolution is not only relevant to biological evolution but essential for some people to be able to understand that evolution is a real process that actually happens and no some much more restricted thing they have been told to believe it is.

Even within the context of biological evolution the statement "Evolution is the change in the inherited phenotypic traits (characteristics) of biological populations over successive generations", is not entirely a true statement. That does describe what is generally meant in that context, but it certainly is not descriptive of evolution in a broader sense, and the I would think the evolution page, if it is going to be about only one facet or one category of evolution, should at least put it into the context of evolution in the broader sense, from the start.

While there is a link to the disambiguation page at the top of the evolution page, its disambiguation page starts out with "Evolution is the change in traits of biological organisms over time due to natural selection and other mechanisms", which again is not a true statement, outside of a very specific context.

Anyway, progress has been made in my absence, and after this latest experience I would rather avoid editing pages in Wikipedia when not specifically asked to, except for perhaps occasional minor edits. Perhaps in time that will change, but right now I'm still recovering from the trauma. Thanks for doing what you felt was right, and again I apologize for my wording in describing what it looked like to me at the time.

DonaldKronos (talk) 21:44, 27 December 2014 (UTC)

You need to read the history of this article. You aren't making any arguments that haven't been thoroughly vetted over the years. You keep saying the article is not fully descriptive of "evolution" but then don't say what "you think" it is and should say-so you aren't making an argument just a complaint. The intro, suppose to be general, covers descent with modification and a basic definition (which the wording has changed to and fro back and forth-but still the same intent of heritable traits changing with successive generations-which is common to all encyclopedic articles and most intro biology text books. It isn't suppose to be evolution by Futyama or Jablonka or Dobzhansky, etc. I've always thought the article should emphasize the modern synthesis more so that Darwin but the body addresses it. The article has been edited by a number of "card carrying" evolutionary biologist yet those changes haven't lasted untouched. The article has a difficult time staying stable because everyone who reads the article finds fault and want to change-as I did years ago. I guess it is human nature.

Semi-protected edit request on 1 March 2015

For greater clarity and precision in the first line change: "Evolution, also known as descent with modification, is the change in heritable phenotype traits of biological populations over successive generations." "Evolution, also known as descent with modification, is the gradual change in heritable phenotype traits and genotype genetic information of biological populations over successive generations." as evolutionary change is not rapid and evolutionary change affects both the outward appearance and the genetics from which the outward appearance is derived.

comment: Whose perspective of "gradual" are we using? Humans'? Bacteria's?--Mr Fink (talk) 20:41, 1 March 2015 (UTC)

I'm not keen on using the word "gradual" based on sources that discuss variability in rates of evolution; "heritable" implies genetic; and "genotype genetic information" is redundant and poorly stated. Personally, I'd prefer something simple and clean:

"Evolution, also known as descent with modification, is change in heritable traits of biological populations over successive generations."

This is true to synthetic sources (e.g., Richard Lewontin's review, Wilson and Bossert's primer, and Ernst Mayr's books) and easy to understand, and technical terms genotype and phenotype explained subsequently. While it may be good to refine the lede, I'd suggest cleaner organization for the overall article first. I can bring an example clean outline back from archived discussion if anybody is ready to tackle this. TheProfessor (talk) 01:30, 2 March 2015 (UTC)

Adding "gradual" would be redundant in that sentence that ends with "successive generations". Capeo (talk) 03:28, 2 March 2015 (UTC)

Here is a summary of the 2 proposals, to help discussion...

Evolution, also known as descent with modification, is the change in heritable phenotype traits of biological populations over successive generations.

Evolution, also known as descent with modification, is the gradual change in heritable phenotype traits and genotype genetic information of biological populations over successive generations.

Evolution, also known as descent with modification, is change in heritable traits of biological populations over successive generations.

Concerning the original proposal by Dtheis:

• Concerning the addition of the word "gradual" I don't think it adds much. An obvious answer to Mr Fink's concern is that as writers for humans we use the perspective of humans, but I am not saying you have no point. I think Capeo hits the nail on the head though, by pointing out that the rapidity (or lack thereof) is depending on generation length. I think our human readers will "get" what that means, i.e. that this will often mean "gradual", while at the same time this wording allows for those fast breeding bacteria.
• No one has commented above on the second aspect of the change which is including not only phenotypic evolution, but also less visible genetic evolution. Seems worth considering? However...

Concerning the second proposal by User:TheProfessor, perhaps it can be understood as a kind of reply to the second change though, by avoiding reference to either genetic or phenotype. I suppose, this raises the question of why the word phenotype was included to begin with. I suppose the reason was that not everyone would call every genetic mutation "evolution". Throughout any population, there are constant differences between individuals which are said to be in the same population, but at least according to the common use of the word, such variations are not all "evolution". I think this is because our language and "common sense" still refers to things called "species" whereas evolution basically means the species are not fixed. They really are constantly evolving and in a state of change, with no particular direction except whatever happens to survive. So I think the wording we currently have is a concession to standard ways of speaking. Anyway, for the time being I personally have no strong opinion on any of these proposals, but I hope the above helps show some key pros and cons. I suppose if all are reasonably acceptable, the proposal of TheProfessor is at least the shortest.--Andrew Lancaster (talk) 09:49, 2 March 2015 (UTC)

Previously the opening sentence read as follows: Evolution is the change in the inherited characteristics of biological populations over successive generations. Either "heritable traits" or "inherited characteristics" would be good. Population geneticists refer to "change in gene frequency in a population" with the emphasis on genotype change, whereas systematists refer to "change in characters" inferred by phylogenetic analysis and with the emphasis on phenotype change. The language "heritable trait" or "inherited characteristic" implies the change is both phenotypic and genotypic (as compared with non-heritable traits or unexpressed genes). Again, I favor simplicity and clarity, including minimal links true to the crafted language and not fashioned by the title of the article to which a link is added. Note that mutation, random fluctuation, selection, assortative mating, and migration in or out of a population all result in evolution. Note that "character" refers to "taxonomic character" (morphological, physiological, molecular, behavioural, ecological, or geographic). TheProfessor (talk) 12:41, 2 March 2015 (UTC)

While we are at it, let's also consider simplifying the second sentence as follows:

Evolutionary processes give rise to diversity at every level of biological organisation, including at the level of species, individual organisms, and molecules.

Currently the second sentence is worded to expose the titles of articles in links rather than crafted for simplicity and clarity. TheProfessor (talk) 13:02, 2 March 2015 (UTC)

Here is a quote from page 3 of Stickler's Evolution (4th ed) by Brian K. Hall and Benedikt Hallgrímsson, to remind us that this is based on reliable sources:

Biological evolution is concerned with inherited changes in populations of organisms over time leading to differences among them. Individuals do not evolve, in the sense that an individual exists only for one generation. Individuals within each generation, however, do respond to natural selection. Genes within individuals (genotypes) in a population, which are passed down from generation to generation, and the features (phenotypes) of individuals in successive generations do evolve. Accumulation of heritable responses to selection of the phenotype, generation after generation, leads to evolution: Darwin’s descent with modification.

All organisms, no matter how we name, classify or arrange them on The Tree of Life, are bound together by four essential facts:

1. They share a common inheritance.

2. Their past has been long enough for inherited changes to accumulate.

3. The discoverable taxonomic relationships among organisms are the result of evolution.

4. Discoverable biological processes explain both how organisms arose and how they were modified through time by the process of evolution.

TheProfessor (talk) 13:44, 2 March 2015 (UTC)

The heritable traits or characters sounds best-strange the phenotype was used. A genetic change can be heritable and passed on for thousands of years till evolution finally acts on itt-like fruit flies resistance to synthetic pesticides is from a transposon mutation that's been jumping around for tens of thousands of years yet only in the last 200 years with synthetic pesticides has natural selection found a use for the heritable trait as it conferred resistance to these pesticides and increasing the allele such 80% of the planets population of flies have this trait.

Several things...

• TheProfessor can you start a new thread if you want to discuss the second sentence? I do recall something of the careful discussion which led to it, and I think you might be under-estimating the reasoning put into it. It was not just to add links, but also to help readers avoid a common misunderstanding.
• Concerning the first sentence I see that one thing needing consideration is why we need the words "also known as descent with modification"? Is this even a common term?
• I remain open to the idea of removing the specificity of phenotypes. Thanks for the extra discussion about that TheProfessor, but I am not quite sure I get the relevance of GetAgrippa's reply, which is maybe heading towards a reason for questioning that proposal?--Andrew Lancaster (talk) 09:52, 4 March 2015 (UTC)

Maybe I was confusing. I'm stating that all populations have natural variation-genetic or epigenetic that produce a phenotype-all the traits of an organism, and evolution is the processes that select on the natural genetic variation (remember too some areas of genomes are 100% conserved across a phyla) such heritable traits that increase reproduction and survival will likely gain in appearance and be maintained by the selective pressure in successive generations. However any give trait maybe selected on by different evolutionary mechanisms and maybe expressed differently within a population so bimodal, etc. Note too a single gene change can be pleiotropic and produce multiple alterations of a phenotype. So I'm saying the genetic change and heritable trait evolution is acting on can associate with numerous phenotypes within a population-so you can have a curly wing fly with pesticide resistance and a normal wing fly with pesticide resistance. So they share a common acquired trait that evolution made more common but then too still have variation in other traits creating different phenotypes. Dang now I'm more confused. LOL. After further consideration I think what I am trying to say is a phenotype is all the traits that evolution acts on and one trait maybe acted on by natural selection and another by genetic drift etc. So absolutely the "phenotype" is important bur for a simple definition heritable trait seems more understandable but maybe put "phenotype" in hypothesis-with as a link to that article? Surely that has muddied the waters-dang it. GetAgrippa (talk) 16:25, 4 March 2015 (UTC)

If I may offer another way to look at what I think we are discussing, it is the question of how to allow that first sentence to cover quite a few options. (I think in past discussions it was pretty clear Wikipedia does not want to try to make a favored narrow definition.) One way to make a sentence cover a lot of options is to make the sentence simple, and using very general terms. Another way is to make the sentence complicated, trying to name all the options. Does that help?--Andrew Lancaster (talk) 10:14, 5 March 2015 (UTC)

Thanks for your comments. Let's keep this simple, clear, and in keeping with reliable sources (e.g., Hall and Hallgrímsson cited in the current version). I favor using either "heritable traits" or "inherited characteristics". The terms "phenotype" and "genotype" are explained later and in the links. Note the links to Heredity and Phenotypic trait lead to appropriate articles. I'm okay with keeping "descent with modification" (Darwin's term) or moving this to later. TheProfessor (talk) 13:05, 5 March 2015 (UTC)

Simple sounds good if we can achieve it. So are we proposing "Evolution is the change in the heritable traits of biological populations over successive generations"?--Andrew Lancaster (talk) 16:18, 5 March 2015 (UTC)

I proposed the following (including links and bolding):

Evolution, also known as descent with modification, is change in heritable traits of biological populations over successive generations.

TheProfessor (talk) 17:43, 5 March 2015 (UTC)

OK then, that means you do not propose removing "also known as descent with modification" but as mentioned above it would be good to remind ourselves why we need or want such words. Is this really very commonly used terminology for evolution? By putting it in the first sentence we imply these terms are almost as common as the term evolution itself which seems strange to me.--Andrew Lancaster (talk) 11:15, 6 March 2015 (UTC)

Well I agree that decent with modification shouldn't be left in, though popular, because it is misleading as much of evolution is maintenance of traits. I agree too that "heritable trait" is simpler (I did say that in my rambling fun) and focuses on a trait rather than a phenotype and combinations of all possible traits which gets complicated with epistasis. I don't think the article should get bogged down in molecular evolution or phylogenetic because there are articles that discuss it more fully so just refer to articles in body of text. Molecular evolution is the engine of variation that biological evolution acts on-it doesn't matter if you are a selections , mutationist, or neutralist. Evolution has filtered the by products of molecular evolution such there are hot spots prone to change but then too areas conserved (like regions of all Chordates 100% conserved ). Man this article has it's own evolutionary history and now back to earlier versions-keep reinventing the wheel it seems. Regards, GetAgrippa (talk) 13:10, 6 March 2015 (UTC)

Above I said I'm okay with either keeping "descent with modification" (Darwin's term) or moving it to later. "Descent with and without modification" is not very catchy (also WP:OR), and it is not so common at the term "Evolution", so let's strike "descent with modification" from the first sentence as follows:

Evolution is change in heritable traits of biological populations over successive generations.

Could we reach consensus and move on? Thanks to those who know the history for insight, encouragement, and leadership. TheProfessor (talk) 15:10, 6 March 2015 (UTC)

I am ok with that. Not sure if we need more input for a first sentence change, but the sentence is really just a simplification.--Andrew Lancaster (talk) 16:50, 6 March 2015 (UTC)

Based on our discussion I changed the lede sentence to the simplified version. I would like to add back "descent with modification", perhaps up front, and perhaps in the paragraph about Darwin and natural selection. I really like the Understanding Evolution website at UC Berkeley (http://evolution.berkeley.edu). They use "descent with modification as the main definition, followed by "small-scale" and "large-scale evolution" definitions (http://evolution.berkeley.edu/evosite/evo101/IIntro.shtml):

Biological evolution, simply put, is descent with modification. This definition encompasses small-scale evolution (changes in gene frequency in a population from one generation to the next) and large-scale evolution (the descent of different species from a common ancestor over many generations). Evolution helps us to understand the history of life.

TheProfessor (talk) 19:25, 7 March 2015 (UTC)

Sounds reasonable to me. Yes the Berkeley site is great and most intro biology text mention "Descent with modification". Which I agree (and describes micro and macro evolution) is better than the more specific "shifts in gene alleles with successive generations pop genetic definition that was the definition for some time-though really too restrictive. This really reads well, is simple, and more descriptive. Does it mimic the Berkeley site too much would be my only concern? I really like addressing the differences between micro and macro evolution-an argument many past editors were hesitant to make any distinction. Great job GetAgrippa (talk) 02:34, 8 March 2015 (UTC)

Having some familiarity with past debates about these opening lines I see nothing really controversial about any of the proposals being discussed.--Andrew Lancaster (talk) 10:09, 8 March 2015 (UTC)

This is a direct quote for the Berkeley website. I would favor recrafting the language with a tone suitable for Wikipedia. TheProfessor (talk) 15:55, 8 March 2015 (UTC)

Maybe blend the two-"Evolution is change in heritable traits of biological populations over successive generations.[1] During small scale evolution changes in gene frequency occurs from one generation to the next such traits are differentially expressed across populations, and these changes compound in large-scale evolution as a common ancestor gives rise to new species and new derived traits over successive generations." Or something like that. Regards GetAgrippa (talk) 00:33, 28 March 2015 (UTC)

I take it the above attempt at a new second sentence is only meant to promote discussion because it is written in a confusing way (at least for me).--Andrew Lancaster (talk) 09:00, 30 March 2015 (UTC)

ADDED: Sorry. Of course this is being discussed in a new section below!--Andrew Lancaster (talk) 09:02, 30 March 2015 (UTC)

Simplification of two lede sentences

Let's simplify the second lede sentence as follows:

Current:

Evolutionary processes give rise to diversity at every level of biological organisation, including the level of species, individual organisms, and at the level of molecular evolution.

Proposed:

Evolutionary processes give rise to diversity at every level of biological organisation, including at the level of species, individual organisms, and molecules.

Currently the second sentence is worded to expose the titles of articles in links rather than crafted for simplicity and clarity. TheProfessor (talk) 13:05, 5 March 2015 (UTC)

Why are we linking species, organism and then molecular evolution? Why not link molecules, and then discuss molecular evolution later?   — Jess· Δ♥ 16:01, 5 March 2015 (UTC)

I don't see why we would link to molecules itself, because that is way to general and just going to have readers wondering what on earth the word is doing in this sentence?--Andrew Lancaster (talk) 16:16, 5 March 2015 (UTC)

I don't see how it's any less useful than linking to organisms. The sentence is stating that evolution creates diversity in molecules. Why wouldn't we link to molecules?   — Jess· Δ♥ 17:24, 5 March 2015 (UTC)

I suppose we could link to speciation and ontogeny (or whatever would be appropriate) instead, and then keep the link to molecular evolution. That isn't preferable in my mind, but it would at least be consistent. I'd rather have those terms linked when we actually discuss them explicitly, though.   — Jess· Δ♥ 17:27, 5 March 2015 (UTC)

Ideally the links would provide basics about each level of organization and how it relates to evolution and diversity, in parallel construction for good style and clarity. We could edit the Molecule article appropriately. TheProfessor (talk) 17:52, 5 March 2015 (UTC)

Yes, I agree with that. I'm not sure the molecule article would need to be changed (or could be just to cater to this article), but I agree with the aim. We surely go into some detail about these topics already (including subarticles devoted specifically to evolution); is there a hole in our coverage we're trying to fill? Otherwise, I think just a link to molecule would be sufficient for now, with detailed coverage of molecular evolution later.   — Jess· Δ♥ 19:35, 5 March 2015 (UTC)

I find it hard to follow this approach. Most molecules such as H2O do not evolve, and to make the molecule article all about how molecules evolve would be a bit strange?--Andrew Lancaster (talk) 09:50, 6 March 2015 (UTC)

The question is what are the most appropriate links in the last clause of the sentence (currently species, organism, and molecular evolution, which are not consistent). Instead of linking to Molecular biology, as was pointed out linking to the current Molecule article could be confusing because that article is "way too general" and might confuse readers. A better choice might be linking to the Biochemistry article. In terms of possible changes to the Molecule article, I am not suggesting "to make the molecule article all about how molecules evolve", nor that the molecule article needs to be changed "just to cater to this article". It could be appropriate to add a section in the Molecule article (or perhaps the Biochemistry article) about molecules in living organisms and molecular evolution, with a sentence in the lede of that article about macromolecules in living organisms, such as proteins and nucleic acids, as well as secondary compounds, and how they show great diversity as the result of biological evolution and are useful for understanding function and evolution. I don't favor the alternative of linking to Speciation, Ontogeny, and Molecular evolution. By the way, another alternative is linking to Molecular phylogenetics, but this has more or less the same issue of consistency/parallel links. Maybe we are better off with the current links. Perhaps we need to rethink all this because diversity at different levels of organisation really is about variation between species, and polymorphism in populations of a given species, which can be morphological, behavioural, physiological, molecular, etc. Any more thoughts so we can move forward? TheProfessor (talk) 11:44, 6 March 2015 (UTC)

Various citations are being added to the lede. I favor adding citations in the main text, and only in the lede when needed for quotes, controversy, or the like (per WP:LEAD). TheProfessor (talk) 15:35, 6 March 2015 (UTC)

I was thinking molecular biology was a pretty good link. It seems like it should be an article about the specific types of molecules we want to link to. Indeed molecular evolution might be good also. I just thought molecule would be too broad. Concerning citations, I suppose they are in their because of past debates - in other words potential controversy?--Andrew Lancaster (talk) 16:53, 6 March 2015 (UTC)

I still don't think linking molecule is confusing (we are talking about molecules in that sentence, right? why wouldn't we link it?) But it looks like I'm alone on that point. I don't think it's really a major issue no matter what we do, so feel free to move forward with whatever you feel is best. Thanks :)   — Jess· Δ♥ 17:35, 6 March 2015 (UTC)

I think most readers know what a molecule is but do not realize that they can be involved in biological evolution. Therefore, given that we are not in any case talking about all molecules (we could easily add adjectives in our lead, but why bother?), it seems appropriate to give our readers a link which goes to the actual subject they are most directly explaining what we are referring to. Seems straightforward to me, and the normal way we work. Our reference is to something more specific than molecules.--Andrew Lancaster (talk) 16:59, 7 March 2015 (UTC)

Is ":Evolutionary processes give rise to diversity at every level of biological organisation, including the level of species, individual organisms, and at the level of molecular evolution. accurate? Evolution "can give rise to diversity but it doesn't always". Doesn't evolution" explain" the diversity of life etc rather give rise to it? " Evolutionary processes explain the history and diversity of life on earth at every level of biological organization, including the level of species, individuals, and the level of molecular evolution". GetAgrippa (talk) 00:45, 28 March 2015 (UTC)

So my penny's worth-""Evolution is change in heritable traits of biological populations over successive generations.[1] During small scale evolution changes in gene frequency occurs from one generation to the next such traits are differentially expressed across populations, and these changes compound in large-scale evolution as a common ancestor gives rise to new species and new derived traits over successive generations. Evolutionary processes explain the history and diversity of life on earth at every level of biological organization, including the level of species, individuals, and the level of macromolecules. or molecular evolution. ". Something like that? GetAgrippa (talk) 00:49, 28 March 2015 (UTC)

Maybe a nod to Darwin. "Evolution is simply "descent with modification" such heritable traits of biological populations change over successive generations.[1] During small scale evolution changes in gene frequency occurs from one generation to the next such traits are differentially expressed in/within/across populations, and these changes compound in large-scale evolution as a common ancestor gives rise to new species and new derived traits over successive generations. Evolutionary processes explain the history and diversity of life on earth at every level of biological organization, including the level of species, individuals, and the level of macromolecules" Whew that's a mouthful=maybe too much and just leave it be. GetAgrippa (talk) 02:13, 28 March 2015 (UTC)

I feel "descent with modification" might be a little too complex without a proper explanation. Anybody may feel free to disagree of course but I like your previous description better, without that particular phrase.--Ollyoxenfree (talk) 22:26, 29 March 2015 (UTC)

Yes, the first sentence was discussed in a separate section above and a few editors including me felt it might not be ideal to throw that term into the opening sentence. I think on Wikipedia we have a lot of articles where the opening sentence has too much inserted into it. We must always remember that we can not put everything into the opening sentence. Anything that a general reader might need a bit of help to understand, and which is not part of the definition of the subject, is probably best moved down in the text. Obviously the occasional "also known as" aside within opening sentences is acceptable though.--Andrew Lancaster (talk) 09:05, 30 March 2015 (UTC)

My apologizes I was confused what was in and what was out-just trying to bet the ball rolling again with some activity. I washed my hands trying to write it long ago. The first paragraph has always been problematic-a lemniscate it seems because we come back to the same point. Although I like the sentiments of the Berkley site short scale and changes in gene frequency which can encompass speciation, and then long scale of a tree of life from a LUCA with common ancestors and derived traits. How you word it is no matter to me but I like the ideas conveyed. Also the next paragraph talks about the LUCA and tree of life so it introduces the ideas.

Evolution's Falsifiability and Lack of Conformance with Basic scientific laws

WP:NOTFORUM; no specific change to the article proposed, and no sources provided.
The following discussion has been closed. Please do not modify it.
Why not mention this? No serious evidence which could be used to falsify evolution has ever been mentioned in a paper on it in a peer reviewed journal. Nor is there evidence that matter ever organizes itself into biological structures. Indeed, matter at a microscopic level at the least, always does the opposite and radiates out parts of itself, creating entropy. Thus evolution is thoroughly unprovable hypothesis not a theory as presented hre.Equivocasmannus (talk) 16:25, 9 April 2015 (UTC) Go read the FAQ at the top of the page, especially questions 3, 4, and 7. Ian.thomson (talk) 16:27, 9 April 2015 (UTC) So we should just ignore these errors in evolution on this main page, even though we have an objections to evolution page?

Changing "All life on Earth originated through common descent ...." to "All species on Earth originated through common descent ...."

The first sentence in the second paragraph of the article reads: "All life on Earth originated through common descent from a last universal ancestor that lived approximately 3.5–3.8 billion years ago." Technically that makes no sense since the universal ancestor would be a life form and we are therefore assuming the same fact we are asserting, making the whole thing a little nonsensical. Shouldn't it be that not life but species originated through common descent from a last universal ancestor? Evolution has to do with the origin of species, not the origin of life after all. It is in fact a common source of confusion for people that evolution addresses the origin of life where it really has nothing much to say about it and that would be, in fact, an different study altogether which has an entirely different article (abiogensis, http://en.wiki.x.io/wiki/Abiogenesis). I am relatively new to contributing. If this seems agreeable to everyone could someone else go in and make the change?— Preceding unsigned comment added by 216.15.29.195 (talk)

It's worded like that on purpose, as where does one designate a common ancestor if you understand that the first life forms arose from a billion-years long organic chemical reaction?--Mr Fink (talk) 15:58, 14 April 2015 (UTC)

I am not saying the sources are wrong or the meaning it is essentially getting to is either. Just the wording says that all life on earth comes from a life which presumably is also a life on earth. It looks, at least at first glance, like a tautology to me. It is not an issue with the hypothesis that life arose from chemical reactions or anything else abiogensis suggests. — Preceding unsigned comment added by 128.164.134.121 (talk)

Both Darwin and Wallace acknowledged that Matthew anticipated their work. I think a sentence or two in the history section would be in order. 85.178.211.113 (talk) 15:28, 20 April 2015 (UTC)
