The first programme of Darwin's Dangerous Idea explores the impact of Darwin’s ideas on religion and morality. Andrew Marr discovers that an important part of the Beagle’s mission was to return three natives to their homeland, Tierra del Fuego, at the southernmost tip of Argentina. Years before he reached the Galapagos, they raised questions in his mind about the fragility of civilisation and what it really means to be human. Marr explores how Darwin developed his ideas when he returned to Britain and finally unleashed his theory of evolution by natural selection on the world. Darwin’s ideas are taken up by many of the major thinkers of the late 19th and early 20th centuries: Karl Marx, Friedrich Nietzsche and Sigmund Freud. We discover that his ideas helped motivate the Kaiser’s army in the First World War and would also help convince the United States government to drop its isolationist policy and enter the conflict. In the 20th century, we discover a growing backlash against Darwin’s ideas among fundamentalists from the world’s major religions. At the same time science has been showing that Darwin’s theory of natural selection holds sway over our behaviour - including our morality - as much as it does over the evolution of our bodies. There is significant scientific evidence that suggests that Darwin has returned humanity to nature, in all its wonder, its glory and its danger.

Sir David Attenborough gives his unique perspective on over half a century of innovation in wildlife filmmaking. He revisits key places and events in his filming career, reminisces with his old photos and reflects on memorable wildlife footage - including him catching a komodo dragon and swimming with dolphins. Returning to his old haunts in Borneo he recalls the challenges of filming in a bat cave and shows how with modern technology we can now see in the dark.

Supermarkets are stocked with fruit year round in a global permanent summertime, but despite its accessibility, have we lost the diversity that makes it so special? The second episode of The Fruit Hunters will look at what happens when we abandon the Garden of Eden for an industrialized monoculture. In lush jungles of Borneo, Bala Tingang, an elder of one of the last hunter-gatherer tribes, lives of the wild fruits that are the key to his tribe's survival. And yet, all around the world, natural diversity is being replaced with monocultures, plantations of only one variety, bred for long shelf life and transportability rather than their taste or health properties. Not only is this lost of diversity impoverishing our taste buds, but it has catastrophic implications for our food security. In the vast uniform banana fields of Honduras, Juan Aguilar, a banana scientist, frantically tries to breed a banana resistant to a deadly fungus.

Dr Helen Czerski examines the hottest natural phenomena on the planet - lightning. Bolts of lightning five times hotter than the surface of the sun strike our planet over 3 million times every day - and yet we still know little about this deadly force of nature. Now, specialist photography is revealing how lightning travels through the air, high-speed cameras are unlocking the secrets of upward lightning that's triggered by our urban landscapes, and scientific expeditions are capturing rare images of intense electrical discharges over 80 kilometres wide.

While the immense ecosystem of the Kalahari is characterized by its harsh conditions, it also offers a wealth of resources to the native wildlife. From the burrows of nocturnal bat-eared foxes to the massive colonies of harvester ants, the region provides habitats for a vast array of life.

Monterey Bay on California's coast is one of the most diverse marine ecosystems in the world, its giant kelp forest bursting with life, from microscopic plankton to visiting ocean giants. The secret key to success in such a busy microworld is balance. Steve Backshall guides us through the unique geography of the bay and introduces some of its key characters in a quest to find the one species that keeps life in the kelp forest in check.
