The veteran naturalist investigates two shells that have proved to be winners in evolution - the bird's egg shell and the hard shell of the tortoise. The ostrich egg is so strong it is possible for it to take a person's weight without breaking - so how does a chick manage break out of such a fortress? The evolution of the tortoise shell was for a long time a mystery, and this bony box offers a lot more than just protection

The evolutionary documentary concludes, as David Attenborough profiles the Siamese fighting fish, so aggressive it will fight its own reflection until it is exhausted. He also looks at the kangaroo - once pitted against humans in the boxing ring - which has a kick so strong it can kill

The explorer digs out his rucksack and heads for Windermere in the Lake District. The National Park attracts 18 million visitors each year, and is now a World Heritage site. Here, Paul finds out why the early tourists thought the Lakes was one of the most dangerous spots in the country. He also plunges into the world of long-distance swimming and helps the staff who run the boats on the lake and meets a Holocaust survivor who was airlifted to Windermere in 1945 as part of a mercy mission involving 300 orphans after the Second World War

The explorer heads to Derwentwater and Borrowdale, a region of England susceptible to extreme weather, where he meets some of the locals who have battled against flooding and learned to live with the conditions. Along the way, Paul tells the story of Millican Dalton, the 'Professor of Adventure', who ran his own expeditions in the Lake District more than 70 years ago. He also heads for the summit of Great Gable, one of the Lake's best-known peaks

Coniston Water isn't the biggest of Cumbria's lakes - but it's one of the most iconic and the place where Donald Campbell died trying to break the world water speed record. Paul meets Campbell's daughter Gina and crew member Robbie Robinson, who was there on the fateful day in January 1967 when Bluebird somersaulted and crashed on the water. The explorer also enters a Lakeland bike ride with a difference before ending his visit with a spot of rock climbing at Dow Crag before the ascent of one of the area's best known hills, The Old Man of Coniston

Remote Eskdale is the next destination in the explorer's trek through the Lake District, enjoying the landscapes and meeting its people. The corner of the western Lakes he focuses on is off the normal tourist track, yet boasts England's highest mountain. However, before making the tough climb to the summit of Scafell Pike, Paul meets the folk who run one of the country's most scenic railways, has a close encounter with a vulture, and gets to grips with the locals in a spot of Cumberland wrestling

David Attenborough presents an insight into the most successful animals on the planet. Observing an Arctic fox stalk prey in its -20C environment, he reveals warm-bloodedness as one of the key factors in the mammals' global domination. He also studies marsupials in Australia and Central America, offering a unique view inside a platypus's breeding burrow

David Attenborough offers an insight into insect-eating animals, including shrews that dive under water, moles that can 'swim' in the Namib Desert, and New Zealand bats that hunt in packs on the ground, walking on their wrists and foraging. Plus, how hedgehogs and armadillos liven up their diet with fruit and birds' eggs, while pangolins and giant anteaters survive entirely on a diet of insects

David Attenborough uses advanced surveillance technology to observe the feeding habits of herbivores, including elephants forced to undertake epic migrations to ensure a steady diet of the plants they need to survive. He also considers the habits of the sloth, which takes a month to digest each meal, and reveals scientific research suggesting that grazing wildebeest do not follow the rains as originally thought, but detect trails of phosphorus in the grass

David Attenborough examines the world of rodents, whose constantly growing incisor teeth are used to chisel through any obstacle and range from squirrels and the English harvest mouse to the large South American capybara. He looks at examples of their dental prowess, showing how agoutis in Panama break open rock-hard nutshells and the skills employed by beavers in Wyoming as they fell massive trees to build dams rivalling feats of human engineering
