Human genetic history

I recently watched an excellent documentary about the journey of humans out of Africa in the last 60,000 years or so. It is based on genetic evidence obtained from analysis of markers in the DNA of the Y chromosome which is passed on from father to son.

The documentary is narrated by Spencer Wells a scientist working in this area and author of the books Deep Ancestry: Inside The Genographic Project and The Journey of Man: A Genetic Odyssey.

The figure below is from Deep Ancestry and shows the human journey based both on the Y Chromosome and Mitochondrial DNA (passed from mother to daughter) evidence.

The documentary is entitled Journey of Man – A Genetic Odyssey and is available on line for viewing and downloading. Its well worth the time and effort.
