Hitchhiking Bacteria Ride Meteorites to Earth: "There is mounting evidence that life originated off earth, traveling here from far, far away on chunks of rock and ice.
The original space travelers appear to be bacteria who, even on earth, survive against all odds in some of the most unlikely places. Research in Siberia, Alaska and Antarctic, for example, reveals live bacteria in glaciers and ice wedges. Apparently the clever microbes can simply melt a bit of ice around them and snuggle in; no need even to desiccate or sporulate."
