Study shows unusual microbes hold clues to early life

Researchers discovered a group of deep-sea microbes called Hydrothermarchaeota that thrive in extreme environments and have never been cultivated. These microbes use an unusual metabolic process to obtain energy from carbon monoxide and sulfate, which could provide insights into the evolution of life on Earth.
