Savage Family, Walking with Cavemen, BBC Documentary Series. Episode 3
In the third episode, Homo ergaster is depicted as the first creature to master the art of tracking. This was made possible because their diet has grown increasingly more carnivorous, and the nutrients in meat made them even smarter than H. habilis of the previous episode. They also begin to form into tribal societies, with genuine bonds between their men and women, though violence is still occurring. As H. ergaster no longer use their arms to walk or climb trees, the muscles of their chests enable them to issue particular sounds, a primitive language. The episode later shows H. ergaster spreading into Asia, becoming Homo erectus and encountering the enormous herbivorous ape Gigantopithecus, the original King Kong. However, for the next million years, H. ergaster are shown harnessing fire and beginning to break away from their direct dependence on their environment.
