A remote expedition to the deepest layer of the Earth’s oceanic crust has revealed a new ecosystem living over a kilometre beneath our feet. It is the first time that life has been found in the crust’s deepest layer, and an analysis of the new biosphere suggests life could exist lower still. (…)
They found communities of bacteria that were sparse but widespread. (…) This is similar to the bacteria found in oil reservoirs and contaminated soil, which could mean that the bacteria migrated down from shallower regions rather than evolving inside the crust, the team say.
