Walking with Cavemen

Journeying millions of years into the past, Winston goes on the trail of Australopithecus afarensis, an ape who took the first step towards modern man.

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 Winstons series on human ancestry travels back one-and-half million years to explore this innovative creature.
