Proteoarchaeota

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

 
 
 

Crenarchaeota

 
 
 
 

Aigarchaeota

 
 

Geoarchaeota

 
 
 
 

Thaumarchaeota

 
 

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, Aigarchaeota, Crenarchaeota, and Korarchaeota. Because of the unsettled phylogeny of the group, the names Proteoarchaeota and TACK may become distinct after further re-organization.
gollark: I did NOT say communism, and I disapprove of it.
gollark: It is unlikely to be abolished unless someone works out a way to utterly overhaul many sociological systems.
gollark: Is 43 even a prime number?!
gollark: GTech™ monitoring drones take at least 22GphotoHz, however.
gollark: You probably would, technically, but not practically.
