This episode travels back in time to Ethiopia 3.2 million years ago to witness the beginnings of mankind. It follows a group of Australopithecus, a type of ape which, just like us, walks upright on two legs. But unlike us, these early members of the human family were not predators, they were prey. Things get worse and worse for the group as they are hunted by a sabre tooth cat called Dinofelis and fall victim to other dangers such as malaria, rival Australopithecus and a rampaging fourteen tonne Deinotherium.
