(Life On Earth [VHS] series, Part 12)
How primates solved the survival problems of life in the trees through the development of binocular vision and grasping hands is fully examined in this episode. Features parts 24 & 25 of the 16mm film version of the 'Life on Earth' series.
Part 24, A Life In the Trees: Two ways primates solved the problems of life in the trees were the development of binocular vision and grasping hands. Presents lemurs on the island of Madagascar, ground-dwelling monkeys in Japan, chimpanzees on the shore of Lake Tanganyika and mountain gorillas in the highlands of Rwanda (26 minutes).
Part 25, The Primates: Grasping hands and binocular vision are the common characteristics of the primates, but they differ in physical size and mobility. Tree-living monkeys in Asia and the apes of Boreno are examined. The gorilla, 10,000 feet up on the sides of a volcano in Central Africa, is shown in his natural habitat. The gorillas prove to be friendly and curious, forming social groups and permanent relationships similar to man. Chimpanzees on the shores of Lake Tanganyika demonstrate the most potent form of social grooming among the primates (23 minutes).
