Ancient DNA with David Reich - TAS 42

Beyond The History and Archaeology Headlines.jpg

Massive technological innovations now allow scientists to extract and analyze ancient DNA as never before, and genomics is emerging as important a means of understanding the human past as archeology, linguistics, and the written word. In his new book Who We Are and How We Got Here (Pantheon), David Reich describes 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. Join Reich as he discusses how the genomic revolution and ancient DNA are transforming our understanding of our lineage as modern humans, and how DNA studies reveal a deep history of inequality—among different populations, between the sexes, and among individuals within a population. He examines how research contradicts the orthodoxy that there are no meaningful biological differences among human populations, at the same time using evidence provided by genomics and ancient DNA to show that the differences that do exist do not conform to familiar and often pernicious stereotypes. Reich, a pioneer in analyzing ancient human DNA, is a professor in the department of genetics at Harvard Medical School and an investigator at the Howard Hughes Medical Institute.
