Proteoarchaeota Explained

"Proteoarchaeota" are a proposed archaeal kingdom thought to be closely related and possibly ancestral to the Eukaryotes.^{[1] [2] [3]}

Classification

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

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.
