Deep beneath the earth's crust, hundreds of metres or kilometres below the surface, with no light, no air, and very little water, in pores and fissures of hard rock, scientists have found an enormous biodiversity of micro-organisms that thrive in extreme conditions. The Dark Biosphere challenges everything we thought we knew and challenges us to rethink not only the origin and evolution of life on Earth but its possible existence throughout the Universe.
