Life exists everywhere on the surface of the Earth and below. Microbial organisms are ubiquitous on Earth, not only the surface but also deep into the crust of the earth, and into the ocean, and into the sediments. I believe that if we ever get out there, if we ever find life in the solar system, I'm going to expect to find it rooted in The Big Tree. And the interesting question is not if it's related, but where is it grouped into the Big Tree.

Pace is both a molecular biologist and a microbial ecologist.
