Scandinavians "genetically diverse" for over 2000 years say researchers

A study of Danish burial grounds dating to the Iron Age by a team of forensic scientists from the University of Copenhagen finds that humans were much more genetically diverse than previously believed.

DNA testing of what was thought to have been a "pure Scandinavian" society shows that at least one of the people was of Arabic origin. The study also demonstrated that villages were not as isolated as previously believed.
