Eukaryogenesis From FECA to LECA: Radical Steps Along the Way
BioEssays, Volume 47, Issue 11, November 2025.How did the last eukaryotic common ancestor (LECA) population evolve? Recent evidence shows an Asgard archaeon‐like organism acquiring a bacterium, the future mitochondrion, going from symbiosis to endosymbiosis. I postulate that almost all salient LECA characteristics could have resulted from the ensuing enhanced ATP generation and internal reactive ...
