It's possible that the family tree of all life on Earth has its roots on Mars — and a new device could put that theory to the test in a few years, researchers say.

Researchers are developing an instrument that would search through samples of Martian dirt, isolating any genetic material from microbes that might be present — bugs that are living or that died relatively recently, within the last million years or so. Scientists could then use standard biochemical techniques to analyze any resulting genetic sequences, comparing them to what we find on Earth.

It’s a long shot,” said MIT researcher Chris Carr, who's working on the life-detecting device, in a statement. But if we go to Mars and find life that’s related to us, we could have originated on Mars. Or if it started here, it could have been transferred to Mars. [5 Bold Claims of Alien Life] Either way, Carr added, we could be related to life on Mars. So we should at least be looking for life on Mars that’s related to us.
