Search for Adam National Geographic Explorer : Season 19 Episode 13

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.
