WebFor perhaps 2 billion years, bacteria were the only living things on Earth! Although some species can cause disease, humans and other organisms need bacteria to survive. View … WebThis phylogeny (evolutionary tree) depicts the evolutionary relationships between the three domains of life: Eukarya, Archaea, and Bacteria. The two prokaryotic domains (Archaea and Bacteria) each comprise several smaller taxonomic groupings. Within the Archaea are the euryarchaeotes, crenarchaeotes, nanoarchaeotes, and korarchaeotes.
