Humans are everywhere. How did we get from the savannahs of Africa across to the most northern reaches of Alaska and Greenland, to the outbacks of Australia and the islands of the Pacific millennia ago? How did we master fire, figure out how to craft tools and survive the Ice Ages?

In this episode Dan is joined by Professor Chris Stringer, Research Leader in Human Evolution at London's Natural History Museum, to talk about how Homo Sapiens managed to outlive other human cousins like Neanderthals and Denisovans and cross oceans s hape landscapes and one day, build cities and space shuttles.

Produced by James Hickmann, Mariana Des Forges and edited by Tim Arstall.
