No Neanderthal genes; not for you

So much for those theories that perhaps early modern man and Neanderthals interbred:

Scientists who sequenced the mitochondrial DNA of a 38,000-year-old Neanderthal returned no evidence of ancestral interbreeding with our long-lost cousins.

That mild disappointment aside, the study, published today in Cell, is an impressive technical achievement.

"For the first time, we've built a sequence from ancient DNA that is essentially without error," said study co-author Richard Green, a Max-Planck Institute anthropologist, in a press release.
