Martian Meteorites

If life began on Mars and migrated to Earth, it had to have some way to get here.  Maybe it did.

The Curiosity rover, by studying the amount of the inert gas argon in Martian rocks, has clinched the case that some meteorites on Earth do in fact come from Mars.  The argon in those meteorites matches that in the atmosphere of early Mars.
