Understanding how complex eukaryotic cells arose from prokaryotic ancestors represents a major challenge in biology. The main point of contention in refining scenarios of eukaryogenesis revolves around the exact relationship between Archaea and eukaryotes. In the new research, scientists from the University of Texas at Austin and elsewhere have generated 63 new Asgard archaea genomes … Read more
