Fortey travels to the rainforests of Madagascar - an ancient island that has spawned some of the most extraordinary groups of plants and animals anywhere in the world. From beautiful Indri lemurs, toxic frogs, and the cat-like giant mongoose called the fossa, to evolutionary oddities like the giraffe-necked weevil and the otherworldly aye-aye, he uncovers the secrets of the evolutionary niche - examining how, given millions of years, animals and plants can adapt to fill almost any opportunity they find.

[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.

They might be young and vulnerable, but every second of these baby animals' lives is a training ground, preparing them for their destiny as an elite predator. Watch as young lions, coyotes, cheetahs, and foxes engage in the kind of play that prepares them for life at the top of the food chain.

Our planet was once populated by megafauna, big top-of-the-food-chain predators that played their part in balancing our ecosystems. When those megafauna disappear, the result is a "trophic cascade," where every part of the ecosystem reacts to the loss. How can we stay in balance? George Monbiot suggests rewilding: putting wolves, lions and other predators back on top -- with surprising results.
