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.

Formed from the remains of a 2.5 million-year-old imploded volcano, the Ngorongoro crater is a study in contradictions: On one hand, it's a self-sustained and plentiful land that provides for the many animals that call it home. Conversely, its isolation threatens the existence of many of its key species. What does the future hold for this unique habitat?

A look at wildlife in hostile environments, including glow-worms, condors, thorny devils, emperor penguins and polar bears. High in the mountains, deep underground, out in the deserts and at each of our vast frozen poles, animals have had to develop extraordinary resilience to survive. There are many challenges faced by animals living in extreme environments. Superbly adapted to these inhospitable habitats, their fortitude and resilience.

The story of animals surviving one of the harshest seasonal changes on the planet continues. As winter turns to spring, temperatures rise and Yellowstone bursts into life. Beavers feast on new green shoots, baby bison take their first faltering steps and grizzly bear cubs emerge from dens to explore this new green world. But spring is also a perilous time. Wolves are hungrier than usual after slim winter pickings. And rising temperatures melt the vast mountain snow pack, sending a million tons of water flooding into the rivers. Only the toughest will survive.
