Deep in the Mponeng gold mine near Johannesburg, South Africa, a rod-shaped bacterium named Desulforudis audaxviator lives in total darkness. Now scientists have discovered through genetic analysis that this organism also lives in complete isolation. Almost all organisms on Earth live in interdependent communities, but the lonely D. audaxviator proves it's also possible for life to go solo.
