A mysterious group of humans from the east stormed western Europe 4,500 years ago — bringing with them technologies such as the wheel, as well as a language that is the forebear of many modern tongues, suggests one of the largest studies of ancient DNA yet conducted. David Reich, professor of genetics, led the research.
Modern Europeans have genetic ties that bind them together much further back in time than once thought, scientists report after analyzing a prehistoric Russian man’s DNA. Pontus Skoglund, research fellow in genetics, is quoted.
