Where did we all come from? Could we all be descendants of Adam? And if he existed who was he, where did he live and what did he look like? It is a mystery that intrigues us all and questions like these have been asked time and time again but nobody has got close to the answer, until now. Spencer Wells, a leading geneticist and National Geographic Explorer-In-Residence, is setting out on a quest to discover if there was an “Adam” from whom all humans are descended. Wells uses the latest in DNA testing technology to take us on an extraordinary journey across the globe as he traces humanity’s family tree. As we travel through humanity’s genetic past we’ll encounter longstanding mysteries which today’s DNA tools can finally solve. As Spencer Wells follows the Y-chromosomes backwards through the generations the branches of man’s family tree begin to coalesce into a single trunk, pointing to a single Adam. But now that we have found him, what did he look like and how did he live? DNA Mystery: The Search for Adam sets out to find the answers.
