S1E1The Infinite Variety
Jan 16, 197955mThe 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.
S1E2Building Bodies
Jan 23, 197954mBright 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.
S1E3The First Forests
Jan 30, 197954mFor 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.
S1E4The Swarming Hordes
Feb 6, 197955mDavid 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.
S1E5Conquest of the Waters
Feb 13, 197955mFish occur in populations of billions and there are over 30,000 species, more than in any other group of backboned animals. The development of the backbone was a crucial advance in evolution -and it probably came from a most unlikely source, a little jelly-like creature called a sea squirt.
S1E6Invasion of the Land
Feb 20, 197955mSome 350 million years ago, evolution reached one of its most crucial stages when fish crawled from the water onto the land and became amphibians. Today, newts, salamanders, toads and frogs still survive in great quantities, and there is even one species of frog where the male gives birth from its mouth! Presented by David Attenborough.
S1E7Victors of the Dry Land
Feb 27, 197955mDavid Attenborough looks at the history of reptiles, the first back-boned creatures to solve the problems of living high and dry on the land. Their waterproofed skin and sealed eggs enabled the mighty reptiles to rule the world.
S1E8Lords of the Air
Mar 6, 197954mThe story of life, from the first primitive cells to the plants and animals that now live around us. David Attenborough examines the uses and advantages of birds' unique possession - the feather. Man has yet to invent anything that, weight for weight, is as strong as the feather. Feathers are insulators, they provide the surface of the most perfect aerofoils known - bird's wings. Plus they play a central role in courtship.
S1E9The Rise of the Mammals
Mar 13, 197954mMammals have proved to be one of the most adaptable products of evolution. David Attenborough looks at their evolution from reptiles 200 million years ago. This remarkable transition involved the development of mechanisms for regulating body temperature, for allowing the young to develop in the womb and for suckling newborns. Attenborough also explores the South American origins of marsupials and their colonisation of Australia.
S1E10Theme and Variations
Mar 20, 197953mA little furry animal from the jungles of South East Asia, called a tree shrew, has attracted great interest from scientists because it shows how a great group of animals may have originated - the mammals. David Attenborough looks at some of the huge variety of mammals. Bats number over a thousand species, many hunt insects, some sip nectar, drink blood, and even catch fish. Contrast those which use sonar with the great whales that sing, the star-nosed mole and the giant anteater, and the potential variations become dramatically clear.
S1E11The Hunters and Hunted
Mar 27, 197955mDavid Attenborough explores the eternal duel between the hunters and the hunted - one of the driving forces of evolution. As the hunters develop speed and cunning, the prey becomes increasingly fast and wary in order to stay alive. Nowhere is this seen better than on the plains of East Africa.
S1E12Life in the Trees
Apr 3, 197955mDavid Attenborough's now-legendary encounter with young gorillas is featured in this episode as he looks at the history of primates, whose ancestors sought their fortune in the treetops. There they developed binocular vision for accurately judging distances, and the ability to grasp trees with a firm grip. The group includes dazzling gymnasts, deafening choristers and highly cultured monkeys.
S1E13The Compulsive Communicators
Apr 10, 197954mDavid 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.
