Talk about an extremophile deep in the Earth! Trouble is we don’t know that life started out like audaxviator. It could just as easily be that one late-arriving microbe could inhabit that territory but nothing else could.
Researcher: “The best explanation we have at the moment is that these microbes did not change much since their physical locations separated during the breakup of supercontinent Pangaea, about 175 million years ago,” Stepanauskas said. “They appear to be living fossils from those days. That sounds quite crazy and goes against the contemporary understanding of microbial evolution.”
