The Compulsive Communicators
David Attenborough looks for crucial clues that help to explain how and why we have come to dominate life on earth. He traces back the African origins of humans to nearly three million years ago, and along the way he goes into caves in southern France where Stone Age people created imaginative paintings of ice-age animals. He also travels to Papua New Guinea to find some hunter-gatherers who have never before set eyes on white people.

The Infinite Variety
The first ever episode of the landmark natural history series Life on Earth. David Attenborough explores the wildlife and landscape that inspired Charles Darwin's theory of evolution.

Building Bodies
Bright blue starfish, crimson feather stars, shell-less snails in designs as extravagant as any Paris fashion show, shrimps of every colour, others that are transparent - just a sample of the animal wonders to be found in a small area of the Great Barrier Reef.

S1 E3
The First Forests
For most of Earth's history there was no life on land. But over 400 million years ago some tiny plants began an invasion from the water, closely followed by the first animals - the ancestors of millipedes and insects.

S1 E4
The Swarming Hordes
David Attenborough looks at the role of a few of the millions of insect species, some of which have developed extremely close relationships with plants. Insects pollinate flowers and in some cases neither flower nor insect can survive without the other.
