200,000 years ago we took our first steps on the African savanna. Today there are 7 billion of us living across planet Earth. How did our ancestors beat the odds?

This is a global detective story, featuring new fossil finds and the latest genetic research. It’s a story that revolves around a shocking revelation. In prehistoric times, we met and mated with other types of human – like Neanderthals, Denisovans and Homo erectus. This mixing of genes helped us survive – and ultimately thrive.

“Americas” – Learn why an underwater discovery in Mexico may rewrite the story of early migration to the Americas. Colonization was a challenge because a huge ice sheet blocked the route. It’s now believed that humans arrived in the Americas by boat, not on foot. Series: See how the mixing of prehistoric human genes led the way for our species to survive and thrive around the globe. Archaeology, genetics and anthropology cast new light on 200,000 years of history, detailing how early humans became dominant.
