Some 350 million years ago, evolution reached one of its most crucial stages when fish crawled from 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

David 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.

The 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

Mammals 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.

David Attenborough brings us the universal story that unites each of us with every animal on the planet, the story of the greatest of all adventures - the journey through life. In the first episode, animals overcome their first great hurdle - surviving infancy.

In the journey towards adulthood, a moment comes for all animals when they must strike out on their own. With their parents absent they must learn to survive in a dangerous world. At this stage of life every small success may mean the difference between life and death.

Animals must find somewhere to live - a place that provides the necessities of life, shelter from the elements and a refuge from enemies.

Animals must try to gain a position of power in their worlds. The most powerful have best access to food and water, and they are also the most attractive to the opposite sex.

David Attenborough explores the courtship displays of flame bowerbirds and pufferfish.

In this final episode, animals attempt to rear their offspring.

Life Story takes us on the greatest of all adventures - the journey through life.
