    Perhaps there is a link with an unexplained turnover in the genetic pool of Europe.

    DNA Study Reveals Genetic History of Europe

    Co-author Prof Alan Cooper, who is also from the University of Adelaide’s Australian Center for Ancient DNA, said: “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. Something major happened, and the hunt is now on to find out what that was.

    The team developed new advances in molecular biology to sequence entire mitochondrial genomes from the ancient skeletons. This is the first ancient population study using a large number of mitochondrial genomes.

    “We have established that the genetic foundations for modern Europe were only established in the Mid-Neolithic, after this major genetic transition around 4,000 years ago. This genetic diversity was then modified further by a series of incoming and expanding cultures from Iberia and Eastern Europe through the Late Neolithic,” Dr Haak said.

    Whoever brought this new DNA would have likely brought their language too.
