Deep origin of eukaryotes outside Heimdallarchaeia within Asgardarchaeota
Nature, Published online: 07 May 2025; doi:10.1038/s41586-025-08955-7Ancestral reconstruction together with molecular dating of the last Asgard archaea and eukaryote common ancestor suggest that eukaryotes arose from the fusion of a H2-consuming archaeal host and a H2-producing protomitochondrion.
