Journey of man

"How did the human race populate the world? A group of geneticists have worked on the question for a decade, arriving at a startling conclusion: the "global family tree" can be traced to one African man who lived 60,000 years ago.

"Blood as source of information on human population of Earth. New genetic evidence, from thousands of DNA samples taken around the world over the last decade, suggests a common ancestor in Africa 60 000 years ago."
"Geneticist, anthropologist, and historian Spencer Wells talks about his book, The journey of man : a genetic odyssey, published by Princeton University Press. Using slide shows and clips, Wells details his research tracing the human genetic lineage across continents. According to Wells, all human beings descended from a single man, who lived in Africa around 60,000 years ago. After his remarks, Wells answers questions from the audience."
