The Incredible Human Journey
There are seven billion people on Earth, spread out around the globe. According to scientific data, most of us can trace our ancestors back to a small number of people who fled Africa some 70,000 years ago. Dr. Alice Roberts traces the archaeological and genetic footsteps of our ancient ancestors in this five-part series to learn how their voyages shaped our species into the people we are today, and how Homo Sapiens came to dominate the earth.
