"Proteoarchaeota" are a proposed archaeal kingdom thought to be closely related to the Eukaryotes.[2][3][lower-alpha 1]

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
TACK /

"Korarchaeota"

Thermoproteota

"Aigarchaeota"

"Geoarchaeota"

Nitrososphaerota

"Bathyarchaeota"

Eocyta
Asgard /

"Lokiarchaeota"

"Odinarchaeota"

"Thorarchaeota"

"Heimdallarchaeota"

(+ α-Proteobacteria)

Eukaryota

"Eukaryomorpha"

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 may become distinct after further re-organization.
