More than a billion people around the world commute into cities each day, and they are not alone. The world's wildlife is commuting too. A steady flow of animals journey in and out of cities to find food and shelter or to start a family. Leaving the wilderness they must overcome the unique challenges that the urban world throws at them to benefit from the opportunities on offer. This episode explores whether the secret to an animal's success in this fast-changing world is to keep one foot in the wild and one in the city, becoming a wild commuter. It seems that all over the world animals are finding that the city can offer opportunities that are harder to come by in the natural world. Some, like African penguins, whose population has plummeted by 80 per cent in the last 50 years, find shelter in the city. By nesting in Cape Town they are safer from predators, and with relatively easy access to their fishing grounds they have the best of both worlds. Many other animals commute into cities because they are filled with food. In St Lucia, South Africa, that includes hippos. Able to eat up to fifty kilograms of grass in a single sitting, they have developed a taste for the short, manicured lawns and come to town every night to dine out. St Lucia's human residents have learnt to give the hippos the space they need during their night-time raids. Black bears need to eat more than 20,000 calories a day to survive their six-month hibernation through winter, and using their acute sense of smell they can easily track down leftovers. In North America they come into towns and cities in search of food. Many animals displaced from their natural habitat are now using their wild skill set in the city to help fulfill their needs. Could this be the beginning of a new and very modern migration?

For the last decade, a team of frontline medics has been fighting to save Borneo's critically endangered orangutans. Armed with cameras, International Animal Rescue has documented their struggle: pulling apes from devastated jungle, giving emergency medical care, rehabilitating and releasing the healthiest orangutans back into the wild. This is both the story of their life-saving work and of how one of our closest wild relatives has been pushed to the brink of extinction. Combining genuine rescue footage with contributions from experts throughout, this documentary looks toward the future and asks what hope remains to save the orangutan.

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.
