DNA evidence points to a massive stone age population collapse
A stone tomb near Paris held generations of dead, but the people buried there did not all belong to the same world. That is the striking picture emerging from new genetic work on 132 individuals buried at Bury, a large Neolithic megalithic site about 50 kilometers north of Paris. The tomb was used in two separate phases, first around 3200 to 3100 BC. Then it was used again across much of the third millennium BC until about 2450 BC. Between those periods, something appears to have gone badly wrong. The break is not subtle. The people buried in the earlier phase were not closely related to the later group. Instead, the DNA points to a major population turnover. This fits into a broader pattern of demographic upheaval that seems to have affected much of northwestern Europe at the end of the fourth millennium BC. “We see a clear genetic break between the two periods,” said Frederik Valeur Seersholm, an assistant professor at the Globe Institute at the University of Copenhagen and one of the study’s …
