Proteoarchaeota is a proposed archaeal kingdom thought to be closely related and possibly ancestral to the Eukaryotes.[2][3][a]

Classification

edit

The phylogenetic relationship of this group is still under discussion. The relationship of the members is approximately as follows:[4][5][6][7]

Proteoarchaeota

Notes

edit
  1. ^ Approximately the same group is sometimes referred to as TACK after the initial letters of its early-found daughter clades: Thaumarchaeota (now Nitrososphaerota), "Aigarchaeota", Crenarchaeota (now Thermoproteota), and "Korarchaeota". Because of the unsettled phylogeny of the group, the names "Proteoarchaeota" and TACK may become distinct after further re-organization. (Indeed, the addition of the Asgard group has made the two entities distinct.)
