The genetic lineage of Europe mysteriously transformed about 4,500 years ago, new research suggests.
The findings, detailed today (April 23) in the journal Nature Communications, were drawn from several skeletons unearthed in central Europe that were up to 7,500 years old.
"What is intriguing is that the genetic markers of this first pan-European culture, which was clearly very successful, were then suddenly replaced around 4,500 years ago, and we don't know why," said study co-author Alan Cooper, of the University of Adelaide Australian Center for Ancient DNA, in a statement. "Something major happened, and the hunt is now on to find out what that was."
