BBC Life On Earth Disc 4: A Life in the Trees (1979)

Some mammals took to climbing trees. To do that, they needed hands that could grasp and eyes that both looked forward to help in the judging of distance. The first to do so were creatures very like the bush-babies and lemurs of today. As time passed monkeys appeared. One group of their descendants became rather bigger and lost their tails. Their descendants included chimpanzees, gorillas - and ourselves.

Peter's DVD rating:
David Attenborough traces the evolution of primates. He seems to focus on the primates' agility in the trees, though other animals such as squirrels are equally aboreal. But certainly without those forward-looking eyes and grasping hands the world would be very different today. Some of the footage, such as the Orangutan and the Chimpanzee using a stick, seem ancuent, but overall this is great nature documentary, and Attenborough waxes most eloquent when he describes the affinity of the Gorilla to humans.
