Proteoarchaeota is a proposed archaeal clade thought to be ancestral to the eukaryotes. ^{[3] [4] [a]}

Classification

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

Proteoarchaeota	Thermoproteati  / "Korarchaeota" Thermoproteota "Ca. Augarchaeota" "Ca. Geoarchaeota" "Ca. Nitrososphaerota" "Ca. Bathyarchaeota" "TACK" / "Eocyta" Promethearchaeati  / Promethearchaeota "Ca. Odinarchaeota" "Ca. Thorarchaeota" "Ca. Heimdallarchaeota" Eukaryota "Asgard"

Notes

1. Approximately the same group was sometimes referred to as "TACK" after the initial letters of its early-found daughter clades: "Thaumarchaeota" (now "Nitrososphaerota"), "Aigarchaeota", "Crenarchaeota" (now Thermoproteota), and "Korarchaeota".
