"A groundbreaking book about how technological advances in genomics and the extraction of ancient DNA have profoundly changed our understanding of human prehistory while resolving many long-standing controversies. Massive technological innovations now allow scientists to extract and analyze ancient DNA as never before, and it has become clear--in part from David Reich's own contributions to the field--that genomics is as important a means of understanding the human past as archeology, linguistics, and the written word. Now, in The New Science of the Human Past, Reich describes with unprecedented clarity just how the human genome provides not only all the information that a fertilized human egg needs to develop but also contains within it the history of our species. He delineates how the Genomic Revolution and ancient DNA are transforming our understanding of our own lineage as modern humans; how genomics deconstructs the idea that there are no biologically meaningful differences among human populations (though without adherence to pernicious racist hierarchies); and how DNA studies reveal the deep history of human inequality--among different populations, between the sexes, and among individuals within a population"--

This book explores changing American views of race mixing in the twentieth century, showing how new scientific ideas transformed accepted notions of race and how those ideas played out on college campuses in the 1960s. In the 1930s, it was not unusual for medical experts to caution against miscegenation, or race mixing, espousing the common opinion that it would produce biologically dysfunctional offspring. By the 1960s the scientific community roundly refuted this theory. The author traces this revolutionary shift in scientific thought, explaining how developments in modern population biology, genetics, and anthropology proved that opposition to race mixing was a social prejudice with no justification in scientific knowledge. In the 1960s, this new knowledge helped to change attitudes towards race and discrimination, especially among college students. Their embrace of social integration caused tension on campuses across the country. Students rebelled against administrative interference in their private lives, and university regulations against interracial dating became a flashpoint in the campus revolts that revolutionized American educational institutions. The author's provocative study is a personal one, featuring interviews with mixed-race couples and stories from the author's student years at the University of Pittsburgh. As such, this book offers a unique perspective on how contentious debates taking place on college campuses reflected shifts in race relations in the larger society. -- from Back Cover
