David Reich, professor of genetics at Harvard Medical School and of celta vs levante human evolutionary biology in Harvards Faculty of Arts and Sciences, explains how ancient DNA is rewriting what we thought we knew about human history. Drawing on more than 50,000 ancient and modern genomes his lab has studied, Reich shows that the people living in a place today are almost never the direct descendants of the people who lived there before migration, audi q9 mixture, and population turnover are the rule across human history, not the exception.
