Europeans appear to be more closely related than previously thought. Scientists who compared DNA samples from people in different parts of the continent found that most had common ancestors living just 1,000 years ago. The results confirm decade-old mathematical models, but will come as a suprise to Europeans accustomed to thinking of ancient nations composed of distinct ethnic groups like "German," "Irish" or "Serbs." What's remarkable about this is how closely everyone is related to each other.
Graham Coop of the Univ. of California, Davis, and Peter Ralph of the Univ. of S. Cal. used a database containing more than 2,250 genetic samples to look for shared DNA segments that would point to distant shared relatives. While the number of common genetic ancestors is greater the closer people are to each other, even individuals living 2,000 miles (3,220 km) apart had identical sections of DNA that can be traced back roughly to the Middle Ages.
The findings indicate that there was a steady flow of genetic material between countries as far apart as Turkey and Britain, or Poland and Portugal, even after the great population movements of the first millenium A.D. such as the Saxon and Viking invasions of Britain, and the westward drive of the Huns and Slavic peoples.
