Searching for the 'real' waterworld
...fe's origin in deep oceans is that it requires hot springs on the ocean floor, heated by volcanic activity like the 'black smokers' found here on Earth. On a waterworld however, 5000 kilometres of ice separate the ocean floor from any possible smokers. On the other hand, a water-surface origin may still be p...New research challenges prevailing theory of microbial biodiversity
