No Neanderthal Ancestors for Modern Humans

If ancient homo sapiens got it on with their Neanderthal
cousins, there were no children to show for it. Researchers studying
Neanderthal DNA have sequenced half of the Neanderthal genome, and
shoot down the theory that European humans interbred with the
now-extinct species. And the team says the genome has other things to
teach us about Neanderthal life, including their sexual proclivities.

research team at the Max Planck Institute for Evolutionary Anthology
presented their findings last week at a human evolution conference. The
researchers have compared the Neanderthal genome to that of modern
humans of European and African descent. Because Neanderthals and modern
humans coexisted in Europe, researchers have theorized that European
genomes would have more similarities with the Neanderthal genome than
would African genomes. However, European and African genomes have a
similar number of differences from the Neanderthal genome, suggesting
that modern humans in Europe outbred rather than assimilated the
