Archaea are thought to have a common ancestor with bacteria, but billions of years ago the third domain, eukaryotes, broke off from archaea, eventually developing into plants, animals and us.esearchers say that the heat and geochemical conditions in volcanic regions may be similar to conditions that existed on the young, water-covered, cooling Earth. Almost like a creature from science fiction, the volcanic microbe is different from the two other basic branches of life: bacteria and eukaryotes.
