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.

Their habitat once stretched across the Prairies, but when humans wiped out the one thing they eat, the black-footed ferret disappeared. The only native North American ferret, this mysterious animal became the most endangered species in the world. For many years, they survived only in zoos. Now a fledgling project is attempting to bring the black-footed ferret back to Saskatchewan. This dramatic story of the ferrets’ reintroduction to the wild unfolds in Return of the Prairie Bandit, a new documentary by Kenton Vaughan set in the stunning prairie of southern Saskatchewan.

[3 parts] Steve Backshall explores the world of insects and their close relatives, the arachnids and crustaceans, in order to find out more about their habits and secrets. Ch1. Them and Us Steve Backshall explores the connections and relationships humans have with insects and their close relatives, the arachnids and crustaceans. He begins by revealing how huge armies of driver ants give houses a five-star clean-up in Kenya, while in China, silkworm caterpillars are credited with shaping culture and distribution. He also explains that, despite people's perceptions of these creepy-crawlies, mankind could not live without them. Ch2. Making Worlds Steve Backshall explores the influence that insects and their close relatives, the arachnids and crustaceans, have on the planet's many ecosystems. He reveals how the landscape of South America's grasslands has been created almost solely by one team of bugs - grass-cutter ants - while in east Africa, the savannah would quickly become swamped in dung were it not for the activities of a particular beetle. He also contemplates the idea that without one tiny creature, the blue whale could not exist. Ch3. The Secrets to Their Success Steve Backshall explores why an estimated 10 million species of insects are so abundant, and examines the secrets of their success. In Yellowstone National Park, he reveals how teamwork enables a colony of bees to scare off a hungry bear, and he travels to the Swiss Alps to highlight the relationship between ants, wasps and butterflies.
