National Geographic Explorer Season 2 Episode 9 Explorer: Search for Adam

Analyzing DNA from the cheek cells of a group of Mongolians enabled geneticist Spencer Wells, an Explorer-In-Residence at the National Geographic Society, to figure out whether they were indeed descendants of the notorious warrior who lived 800 years ago and thousands of miles away. Such exotic historical enigmas are daily fodder for Wells who is in the midst of the Genographic Project (GP) a massive undertaking to sample human DNA from around the world to illuminate human genetic and migratory history.
