Proteoarchaeota is a proposed archaeal clade thought to be closely related and possibly ancestral to the eukaryotes. ^{[2] [3] [a]}

Classification

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

Proteoarchaeota	Thermoproteati "Korarchaeota" Thermoproteota "Aigarchaeota" "Geoarchaeota" "Nitrososphaerota" "Bathyarchaeota" aka "TACK", "Eocyta" Promethearchaeati  / "Lokiarchaeota" "Odinarchaeota" "Thorarchaeota" "Heimdallarchaeota" Eukaryota "Asgard"

Notes

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" (syn. Thermoproteati) may become distinct after further re-organization. (Indeed, the addition of the Promethearchaeati has made the two entities distinct.)
