Fortey is on Hawaii to investigate how life colonises a newly-born island. The most remote island group in the world, by some estimates only one new species successfully colonised Hawaii every 35,000 years - yet the Hawaiian Islands teem with a great diversity of life. In search of the evolutionary secrets of how one species becomes many, Fortey encounters beautiful honeycreeper birds whose evolution rivals that of the Darwin's famous finches; carnivorous caterpillars who now can't eat leaves; and giant silversword plants that thrive in parched volcanic soil at 10,000 feet.

Helen looks at the latest scientific insight into the aurora - dancing lights in the night sky that have fascinated cultures throughout our history. From the networks of cameras now capturing its vast scale, to novel experiments that probe the threat it poses to modern technology, Helen reveals the dramatic transformation in our understanding of the aurora, and the many mysteries that remain to be solved.

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.
