They first fought for life when dinosaurs dominated the Earth. And, down through the countless millennia, they have survived. The primates. This is their story.

They walked out of the forests, they became human, they covered the Earth, they fell. But they have survived and they have evolved.

Evolution follows the ebb and flow of one stream in the great river of DNA. Darwinian evolution is dramatised as a constant life and death struggle, a heroic story of endurance. It is a story that transcends generations, species, mankind and, in the end, the Earth itself.
