Nzira dzemazuva ano dzekuronga dzinovavarira kuronga archaea mumapoka ezvisikwa zvine maitiro akafanana uye madzitateguru akafanana. Aya marongero anovimba zvakanyanya nekushandiswa kweiyo ribosomal RNA gene kuteedzana kuratidza hukama pakati pezvisikwa (molecular phylogenetics). Mazhinji emarudzi ane tsika uye akanyatsoongororwa earchaea inhengo dzemapoka maviri makuru, iyo Euryarchaeota uye Crenarchaeota. Mamwe mapoka akagadzirwa zvishoma nezvishoma. Semuenzaniso, iyo yakasarudzika mhando Nanoarchaeum equitans, iyo yakawanikwa muna 2003, yakapihwa yayo phylum, iyo Nanoarchaeota. A phylum nyowani yeKorarchaeota yakapihwawo. Iyo ine chikamu chidiki chezvisikwa zvine chimiro che ribosomal RNA genes kuratidza hukama pakati pezvisikwa (molecular phylogenetics).
