Debate over origins of modern central Europeans

Study points to potential origins of modern central Europeans - Yahoo! News: "Anthropologist Joao Zilhao of the University of Bristol, England, noted that the study didn't compare the DNA of the ancient farmers with that of the ancient hunter-gatherers, adding that there are plenty of hunter-gatherer burials in German cave sites that could have been sampled for comparison.
Without that comparison it's hard to say that the difference between modern DNA and that of the ancient farmers means current people are descended from the ancient hunter-gatherers.
'In this particular case, the reason may be because of a farmer input that was subsequently diluted, assuming that the N1a haplotype is a marker of spreading farmers, and that it was as rare in pre-Neolithic Europe as it is today,' Zilhao said.
But, he added, 'I see nothing in the data that would necessarily carry the exclusion of, for instance, the opposite hypothesis . . . that (the N1a marker) represents the incorporation of hunter-gatherer females in the farming communities that are coming into Europe about 7,500 years ago, that incorporation being in such small numbers that, eventually, it all but disappeared.'"
