Over the course of the Earth's history, about a billion tons of rocks have been exchanged between the Earth and Mars. Scientists think it's possible that one or more of those rocks might have contained tiny microbes that successfully made the journey from one planet to the other. In 2018, they plan to test this hypothesis by searching for Earthling-like DNA under Mars' surface.
