BBC Life On Earth Disc 4: The Compulsive Communicators (1979)

Grasping hands enabled humans to use weapons. So they became hunters. But to kill the powerful plains-living animals, they needed to work in teams. That encouraged the development of language with which to share plans and issue instructions. Eventually, writing enabled them to share their experiences with others remote in both space and time. So human beings set off down the road towards the domination of the world.

David Attenborough traces the development of Homo sapiens in this last program of the "natural history" series. It is a disappointing climax that dwells mostly on drawn-out musings on the ability of humans to communicate. He gives only a cursory treatment of human evolution, and describes only Homo erectus among the early hominid, not even mentioning Australopithecus, H. erectus, or H. neanderthalensis. Even the encounter with the isolated Biame people turn out to be little more than "me Tarzan" gesturing, and we learn that humans from different cultures can, indeed, communicate.
