Some authors have added [[non-cellular life]] to their classifications. This can create a "superdomain" called "Acytota", also called "Aphanobionta", of non-cellular life; with the other superdomain being "[[cytota]]" or cellular life.<ref name="pmidhttps://pubmed.ncbi.nlm.nih.gov/26305806/">{{cite journal|author=Trifonov EN, Kejnovsky E |title=Acytota - associated kingdom of neglected life. |journal=J Biomol Struct Dyn |year=2016|volume=34|issue= 8 |pages=1641–8 |pmid=26305806 |doi=10.1080/07391102.2015.1086959 |pmc= |s2cid=38178747 |url=https://pubmed.ncbi.nlm.nih.gov/26305806/}}</ref><ref name="Biological systematics : the state of the art p.

The [[eocyte hypothesis]] proposes that the [[eukaryote]]s emerged from a phylum within the [[archaea]] called the [[Thermoproteota]] (formerly known as eocytes or Crenarchaeota).<ref name=Archibald>{{cite journal|first1=John M. |last1=Archibald|title=The eocyte hypothesis and the origin of eukaryotic cells |journal=[[PNAS]] |volume=105|issue=51 |pages=20049–20050 |date=23 December 2008|doi=10.1073/pnas.0811118106|pmid=19091952|bibcode=2008PNAS..10520049A|pmc=2629348|doi-access=free }}</ref><ref name=Lake>{{cite journal |first1=James A. |last1=Lake |first2=Eric |last2=Henderson |first3=Melanie |last3=Oakes |first4=Michael W. |last4=Clark|title=Eocytes: A new ribosome structure indicates a kingdom with a close relationship to eukaryotes|journal=[[PNAS]] |volume=81|pages=3786–3790 |date=June 1984|issue=12 |doi=10.1073/pnas.81.12.3786 |pmid=6587394|pmc=345305|bibcode=1984PNAS...81.3786L |doi-access=free}}</ref>
