There are seven billion humans on earth, spread across the whole planet. Scientific evidence suggests that most of us can trace our origins to one tiny group of people who left Africa around 70,000 years ago. In this five-part series, Dr Alice Roberts follows the archaeological and genetic footprints of our ancient ancestors to find out how their journeys transformed our species into the humans we are today, and how Homo sapiens came to dominate the planet.
In this programme, the journey continues into Asia, the world's greatest land mass, in a quest to discover how early hunter-gatherers managed to survive in one of the most inhospitable places on earth - the Arctic region of Northern Siberia. Alice meets the nomadic Evenki people, whose lives are dictated by reindeer, both wild and domesticated, and discovers that the survival techniques of this very ancient people have been passed down through generations. Alice also explores what may have occurred during human migration to produce Chinese physical characteristics, and considers a controversial claim about Chinese evolution: that the Chinese do not share the same African ancestry as other peoples.
The Incredible Human Journey
Dr Alice Roberts travels the globe to discover the incredible story of how humans left Africa to colonize the world.
How did we get here? Following a trail of clues from the latest scientific research, Dr Alice Roberts re-traces the greatest ever journey taken by our ancestors. Thousands of years ago one small group of our species, Homo sapiens, crossed out of Africa and into the unknown. Their descendants faced baking deserts, sweat-soaked jungles and frozen wildernesses and risked everything on the vast empty ocean.
Within 60,000 years they colonised the whole world... How did they do it? Why do we, their descendants all look so different? And what did we have that meant we were the only human species to survive?
Using the evidence from genetics, fossils, archaeology and climatology, Dr Alice Roberts uncovers five epic routes our ancestors took across the globe and the obstacles and brutal challenges they encountered along the way. It reveals how our family tree grew and spread out across the world, producing all the variety we see in the human species today – but despite all that diversity, Alice reveals how astonishingly closely related we all are.
