Between 3.1 and 4.1 billion years ago. Web the last universal common ancestor (luca) is hypothesized to have been a common ancestral cell from which the three domains of life, the bacteria, the archaea, and the. Web in the past, archaea were classified as bacteria and were called archaebacteria.
Web More Reliable Genetic Analysis Revealed That The Archaea Are Distinct From Both Bacteria And Eukaryotes, Earning Them Their Own Domain In The Three Domain Classification Originally.
Web the main question now debated is whether core components of the eukaryotic nuclear lineage descend from a common ancestor shared with archaea, as. Web the timelines of divergence suggest that bacteria (members of the domain bacteria) diverged from common ancestral species between 2.5 and 3.2 billion years ago, whereas archaea diverged earlier: Gene acquisitions for metabolic functions from bacteria represent key.
