The Incredible Human Journey (2009)

There are seven billion people on Earth, spread all over the planet. Scientific evidence suggests that most of us can trace our origins to a small group of people who left Africa 70,000 years ago. In this five-part series, Dr. Alice Roberts traces the archaeological and genetic footprints of our ancient ancestors to learn how their travels transformed our species into the humans we are today and how Homo Sapiens came to dominate the planet.
