Recent genetic research indicates that the human race may be descended from the hybrids of cross-breeding between Chimpanzees and other early primates. The analysis, by David Reich, Nick Patterson and colleagues at the Broad Institute in Cambridge, Massachusetts, is reported in the New York Times, May 18, 2006. The ancestral lines of the Chimpanzee (Pan troglodytes) and of humans (Homo sapiens) originally split from each other between 7 and 6 million years ago, but after this there followed a long period of cross-fertilization. The final split took place about 5.4 million years ago, after which hybridization ceased.
