The origin of eukaryotes is a major open question in evolutionary biology. Multiple hypotheses posit that eukaryotes likely evolved from a syntrophic relationship between an archaeon and an alphaproteobacterium based on H<sub>2</sub> exchange. However, there are no strong indications that modern eukaryotic H<sub>2</sub> metabolism originated from archaea or alphaproteobacteria. Here, we present evidence for the origin of H<sub>2</sub> metabolism genes in eukaryotes from an ancestor of the Anoxyc ...[more]
