This week's programme in the series on Man and Science Today.

The family of man began to evolve from the primate order about 15 million years ago but how have we changed since then? Where did we come from; what did our ancestors look like and how did they live?
The great detective story has traced our origins back to the extinct ape-man of Africa-probably mankind's earliest pre-human ancestor; from the Transvaal comes the skull of an ape-man child, bearing the marks of a fatal leopard attack made about two million years ago. In a pre-Neanderthal cave in the centre of modern Nice detailed analysis of the patterns of shells, rocks, and bones found on the floor has revealed an exact picture of how man once built his camp there 130,000 years ago.
Tonight's Horizon looks at the work of archaeologists and scientists who are digging for similar evidence of man's earlier. existence on sites in Europe, Africa, Australia, and Asia.
