The PEDIGREE of
Proto-Chimpanzee

     recent (2006) DNA evidence suggests that after chimp & hominid diverged, they interbred for a million years

    Note: Why is proto-Chimpanzee shown as Man's direct ancestor? There is disagreement between fossil evidence (Orrorin and Sahelanthropus do not appear to be ancestral to Chimp) and genetic evidence (DNA divergence appears to be less than 6 million years ago). Recently this was resolved by researchers Reich et al, who suggest that after an initial divergence, chimp and hominid continued to interbeed. The pure ``male'' is shown interbeeding with a hybrid ``female'' in the chart because hybrid males tend to be sterile.
