Compulsive Communicators

The final episode deals with the evolution of the most widespread and dominant species on Earth: humans. The story begins in Africa, where, some 10 million years ago, apes descended from the trees and ventured out into the open grasslands in search of food. They slowly adapted to the habitat and grew in size. Their acute sense of vision led to them standing erect to spot predators, leaving their hands free to bear weapons. In addition, the primitive apemen also had stones that were chipped into cutting tools. Slowly, they grew taller and more upright, and their stone implements became ever more elaborate.

The Himalayas

The Himalayas

David Attenborough narrates a documentary looking at the wildlife of the most stunning mountain range in the world, home to snow leopards, Himalayan wolves and Tibetan bears. Snow leopards stalk their prey among the highest peaks. Concealed by snowfall, the chase is watched by golden eagles circling above. On the harsh plains of the Tibetan plateau live extraordinary bears and square-faced foxes hunting small rodents to survive. In the alpine forests, dancing pheasants have even influenced rival border guards in their ritualistic displays. Valleys carved by glacial waters lead to hillsides covered by paddy fields containing the lifeline to the East, rice. In this world of extremes, the Himalayas reveal not only snow-capped mountains and fascinating animals but also a vital lifeline for humanity.
