Theory of Panspermia i believe it is called.
There is a bacteria that can survive extreme heat and breaths iron perfect conditions for the lava vents down in the ocean and asteriods, I think there called extremenites but maybe ther is another name for it. But i doubt humans could have evolved from them. here is an old article I saved a while ago

Panspermia is a definite possibility. That is because bacteria have a unique ability. They can dehydrate and crystallize as a bacterial spore. Bacterial spores millions of years old, preserved in amber, for instance, have been revived. Just adjust the atmosphere, since most are anaerobic (oxygen kills them) and the ones that started life on Earth were probably extremophiles. They are also archaeobacteria, from which descend every other lifeform on Earth.

To survive a long journey through interstellar space, they would have to be encapsulated in a dust particle, which would protect it from UV rays.

If mankind ever becomes star-travelers, it wouldn't surprise me if we found that we share a common ancestry with whatever other life we find on other planets. Same thing if we find life on Mars. Of course, skeptics will claim contamination, yet the reference to www.abc.net.au shows these bacteria could not be terrestrial. If DNA can be derived, it might be shown that they share a common ancestor with us.
