WebFeb 24, 2024 · That Bacteria, Archaea and Eukarya (eukaryotes) represent three separate domains of Life, no one having evolved from within any other, has been taken as fact for three decades. Recent work shows this to be untrue. Eukarya arose from well within Archaea and are specifically related to newly discovered archaeal species with eukaryote-like … WebIn all three domains, the hereditary material is DNA; their cellular metabolism is based on proton gradients which drive ATP synthesis (using the same protein system, ATP synthase); they all have phospholipid-based membranes, and they use protein catalysts (enzymes) to speed up metabolic processes. They use RNA and ribosomes for protein synthesis. This implies that there are only two domains of life, Bacteria and Archaea, with eukaryotes incorporated among the Archaea. Eukaryotes represent a small minority of the number of organisms, but, due to their generally much larger size, their collective global biomass is about equal to that of prokaryotes.
