Who We Are and How We Got Here is a 2018 book on the contribution of genome-wide ancient DNA research to human population genetics by the geneticist David Reich. He describes discoveries made by his group and others, based on analysis and comparison of ancient and modern DNA from human populations around the world. Central to these is the finding that almost all human populations are mixtures resulting from multiple population migrations and gene flow. Several reviewers have praised the book for clearly describing pioneering work in a cutting-edge field of study. It has been criticized by numerous scientists and scholars for its handling of race, though other commentators observe that nothing it says should give racists any comfort. Source: Wikipedia (en)
