Walking with Cavemen

An extraordinary new breed of ape-man called homo ergaster has taken over Africa. They are expert tool-makers, food-finders and travellers, but where they differ most from their predecessors is in their communal lifestyle. The third instalment of Professor Robert Winston's series on human ancestry travels back one-and-half million years to explore this innovative creature.

A focus on a group of Homo heidelbergensis, advanced tool users who lived in family units but who were incapable of imagination, and their descendents the Neanderthals and Homo sapiens, who came to conquer the world.
