The Lost Family: How DNA testing is upending who we are. A conversation with author Libby Copeland.

Over 30 million Americans have taken  DNA Tests at home, largely for recreational genealogy and family history purposes. This vast array of DNA databases has linked millions of distant cousins and newly discovered relations. In a melting pot culture like the United States where we all hail from somewhere else originally, this DNA based family history culture is raising new cultural opportunities, questions and challenges. Libby Copeland gives us a balanced blend of this new genetic science, data collection and how they intersect with human nature and emotions.
