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

Classification

The phylogenetic relationship of this group is still under discussion. The relationship of the members is approximately as follows:

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. (Indeed, the addition of the Asgard group has made the two entities distinct.)
