Modern Europeans Hail From Three Distinct Groups
Friday, January 03, 2014
BOSTON, MASSACHUSETTS—An analysis of the genomes of eight ancient Europeans by an international team of scientists, led by researchers at Harvard Medical School and Germany's University of Tübingen, contradicts the prevailing belief that Europeans are descendants of Middle Eastern farmers that mixed with dispersed bands of hunter-gatherers. The scientists studied DNA from seven hunter-gatherers found in Sweden and one woman found in Luxembourg, all dating to about 8,000 years ago. They found that modern Europeans are primarily made up of hunter-gatherers who migrated out of Africa 40,000 years ago, a later influx of Middle Eastern farmers, and a third population that the team named "ancient northern Eurasians," which ranged from northern Europe to Siberia.
