Asgard archaea
Asgard archaea, or Promethearchaeati (previously known as superphylum "Asgard" or phylum "Asgardarchaeota"), are a kingdom belonging to the domain Archaea that contain eukaryotic signature proteins. It appears that the eukaryotes, the domain that contains the animals, plants, fungi and protists, emerged within the Promethearchaeati, in a branch containing the "Heimdallarchaeia".
