Mr Timothy Jull, who led the research at the University of Arizona at Tucson, said: "The organic material contains 14C (the carbon 14 isotope) and the carbonate doesn't because the carbonate came from somewhere in space, presumably Mars, and the organic material is a recent addition which took place while the meteorite was sitting on the ice.
