Signs of Neanderthals Mating With Humans

Neanderthals mated with some modern humans after all
and left their imprint in the human genome,
a team of biologists has reported in
the first detailed analysis of the Neanderthal genetic sequence.

The biologists, led by Svante Paabo of the
Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany,
have been slowly reconstructing the genome of Neanderthals,
the stocky hunters that dominated Europe until 30,000 years ago,
by extracting the fragments of DNA that still exist in their fossil bones.
Just last year, when the biologists first announced
that they had decoded the Neanderthal genome,
they reported no significant evidence of interbreeding.

Scientists say they have recovered 60 percent of the genome so far
and hope to complete it.
By comparing that genome with those of various present day humans,
the team concluded that
about 1 percent to 4 percent of the genome of non-Africans today
is derived from Neanderthals.
