Journey of Man: A Genetic OdysseyA fantastic documentary tracing the earliest human migration on this planet, as shown by our genetic roots.

This informative film, full of surprising news, is based on the work of Spencer Wells, who is both innovative scientist and enthusiastic host.

He and crew scour the world for indigenous people with deep roots in one place, asking for samples of DNA to test, in order to piece together our "big family" genetic tree.

In Indiana Jones mode, Wells tacks down common ancestors and comes up with some surprising candidates which he interviews.

The best parts are when he returns with DNA results and we see the diverse ways in which people and tribes react to the news of what science says about their arrival and relations. View this as adventure travel or as a painless way to begin your genetic literacy.
