ARCHAEAL EVOLUTION

Eukaryogenesis, a syntrophy affair

Eukaryotes evolved from a symbiosis involving Alphaproteobacteria and archaea phylogenetically nested within the Asgard clade. Two recent studies explore the metabolic capabilities of Asgard lineages, supporting refined symbiotic metabolic interactions that might have operated at the dawn of eukaryogenesis.
