The existence of so-called "extremeophiles" in various inhospitable environments on earth gives hope that life may be found in seemingly unlikely places elsewhere.
One difference, however, is that most such creatures on earth probably arose under more favorable conditions and then migrated and evolved to live where we find the now. Certainly, for example, the shrimp and tube worms living at deep sea vents didn't originally evolve independently from all the other shrimp and worms in the oceans.
On the other hand, it has been suggested that harsh environments should be looked at in the search for the origin of life on earth, since it is certain that the environment where life began was drastically different from what exists today in most of the world.

And now the Russians are saying that it's probably just contamination. I can't imagine how they could avoid contamination, since pretty much everything on earth's surface is packed with bacteria. A complicated effort.
