Although one does not know what travels that microbe has taken during it's 250 millions year hiatus from metabolism, it was found at 1850 feet underground. The other was at "almost 2 miles". Quite a pressure differential.

I'm presuming the one was warm, the other was in a wet-frozen environment.

Putting all the conditions together leaves one a bit awestruck. There is a wide range of conditions in which life has survived if not thrived. It certainly makes it a reasonable expectation that life can be found elsewhere.

I'd love to know how closely extraterrestrial DNA matches the earthbound stuff.
