In some of the world's most spectacular natural wonders, people push themselves to the limit in order to survive. For the people who call these extraordinary places home, survival requires skill, ingenuity and bravery. In Brazil, the Kamayura people of the Xingu Indigenous Park believe they must appease the spirits if they are to remain in good health. In Ethiopia, belief in a higher power leads villagers in the Tigray region to climb a huge, vertiginous mountainside to reach their church. Laos is one of the most fertile places on earth. Despite this, life is dangerous for the rice farmers in this beautiful country. During the Vietnam War, the United States dropped an estimated 270 million bombs on this small country and approximately 80 million of them failed to explode.

This special, narrated by Andrew Scott, celebrates the drama of Autumn and how animals and plants deal with the new challenges it brings. This is the time of year that brings the world's most spectacular transformations. With winter fast approaching, life has to get ready and that means feeding up while you can, fighting for the last chance to breed and rushing to grow up before the cold returns. While chipmunks and beavers dash to stash their winter supplies, many animals from musk oxen to beetles have to battle for mates and young gannets must face life's first dangerous challenges.

In many of the earth's natural wonders there is an abundance of animals. These can be a devastating threat to the people who live there, or they can provide a means of survival, but often at a high price. In the coastal salt marshes of northern Australia's Arnhem Land, Indigenous Australians still go hunting for the eggs of one of the world's most aggressive predators - the saltwater crocodile. Vanuatu is an island paradise in the south Pacific, but life here isn't perhaps as idyllic as it appears. Overfishing has reduced fish stocks, making food harder to come by for the indigenous islanders like 45-year-old Nigasau.

His team works with Russia's most formidable biologists, geomorphologists and ornithologists to understand how climate change is affecting this remote ecosystem. From diving in subzero temperatures to running away from polar bears to avoiding titanic icebergs, the Pristine Seas team faces some of its most dangerous challenges to date.

The episode begins in the South American rainforest whose rich variety of life forms is used to illustrate the sheer number of different species. Since many are dependent on others for food or means of reproduction, David Attenborough argues that they couldn't all have appeared at once. He sets out to discover which came first, and the reasons for such diversity. He starts by explaining the theories of Charles Darwin and the process of natural selection, using the giant tortoises of the Galapagos Islands (where Darwin voyaged on HMS Beagle) as an example. Fossils provide evidence of the earliest life, and Attenborough travels a vertical mile into the Grand Canyon in search of them.
