235: Life on earth tells us about life on Mars

Creatures Frozen for 32,000 Years Still Alive:

A new type of organism discovered in an Arctic tunnel came to life in the lab after being frozen for 32,000 years.

The deep-freeze bacteria could point to new methods of cryogenics, and they are the sort of biology scientists say might exist on Mars and other planets and moons.

Why should Martian life be like terrestrial life? Because the natural processes that produced life here are operating elsewhere. Evolution proceeds from simple mathematical and logical arguments, and those principles apply everywhere.
