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.
