Dr. Reich is a Professor of Genetics at Harvard Medical School. His lab analyzes the DNA of ancient human remains to better understand major human migration patterns, adaptations, and population mixing throughout prehistoric and more recent eras. David’s book, Who We Are and How We Got Here, explores the deep history of humanity and how the discoveries of ancient DNA challenge the popular stories we tell about the past. David joins the podcast to explain why every human outside of Africa has some Neanderthal ancestry and how human migration patterns for tens of thousands of years have reshuffled populations and cultures over millennia.
