Aigarchaeota

Aigarchaeota
Scientific classification
Domain: Archaea
Kingdom: "Proteoarchaeota"
Phylum: "Aigarchaeota" or "Thaumarchaeota"
Species
  • Ca. "Caldiarchaeum subterraneum"

The 'Aigarchaeota' are a proposed archaeal phylum of which the main representative is Caldiarchaeum subterraneum.[1] It is not yet clear if this represents a new phylum or a thaumarchaeal order, since the genome of Caldiarchaeum subterraneum encodes several thaumarchaeal features.[2] The name 'Aigarchaeota' comes from the Greek αυγή, ‘aigi’, meaning dawn or aurora, for the intermediate features of hyperthermophilic and mesophilic life during the evolution of its lineage.[1]
