"...Contrary to what has long been believed, there was no peaceful transition of power from hunter-gather societies to farming communities in Europe, with new advanced DNA analysis revealing that the newcomers slaughtered the existing population, completely wiping them out within a few generations.
Researchers from Sweden's Lund University analyzed skeletons and teeth found in what is now Denmark, and found that 5,900 years ago, the region underwent a swift and total population change. Prior to this, Danish Mesolithic people of the Maglemose, Kongemose and Ertebřlle cultures – genetically related to other Western European hunter-gatherers – were prominent inhabitants. But when Neolithic farmers arrived, an abrupt shift can be seen in DNA records, with next to no genetic contribution from the local hunter-gatherers.
Tracing the DNA timeline, the researchers could see that the hunter-gatherers had been swiftly wiped out by the late Stone Age, in what they suspect was a very bloody and very thorough takeover.
“This transition has previously been presented as peaceful," said Anne Birgitte Nielsen, geology researcher and head of the Radiocarbon Dating Laboratory at Lund University. "However, our study indicates the opposite. In addition to violent death, it is likely that new pathogens from livestock finished off many gatherers."..."
