"Written with much verve, easy to read, and up-to-date on many important developments."--Luigi Luca Cavalli-Sforza, Stanford University, author of "The History and Geography of Human Genes" and "Genes, Peoples, and Languages."
"Spencer Wells, whose genetic work has contributed to our understanding of human prehistory, has provided the lay reader with an account of the spread and mixing of the human species from its origin in Africa that is both scientifically accurate and accessible to the nonscientist. In achieving that accessibility, he has not made the common error of confusing simple explanations with simplistic ones. Most important, Wells has the intellectual integrity, all too rare in popularizations of science, to distinguish what is really known from what is only speculation."--Richard Lewontin, Harvard University, author of "It Ain't Necessarily So: The Dream of the Human Genome and Other Illusions."show more
