Sophie is joined in the theatre by chirping crickets, hissing cockroaches and groaning deer to reveal the very different ways that animals have adapted their bodies to send audible messages that are vital to their species. She also explores how and why the human voice evolved to become the most versatile sound producer in the natural world. She demonstrates what sound actually is and how it travels. Unpacking the power behind sound, she uses it to shatter glass and reveal how the human body can resonate in a way that amplifies our voices to send our messages further. She also explores how different species use very different frequencies to communicate and why humans can only hear a fraction of these animal messages. Finally, she investigates why we all have unique vocal prints, and how computers are learning to recognise these.

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.

"Planet Earth" travels around the Earth, finding where the sun always shines and where it's rarely seen. Next, they find where water is abundant and where it's scarce.

The discovery of biological evolution is among the most significant scientific findings of the last 200 years. It has lead us to thousands of new discoveries and is greatly expanding our understanding of the natural world.

David Attenborough takes a breathtaking journey through the vast and diverse continent of Africa as it has never been seen before. (Part 5: Sahara) Northern Africa is home to the greatest desert on Earth, the Sahara. On the fringes, huge zebras battle over dwindling resources and naked mole rats avoid the heat by living a bizarre underground existence. Within the desert, where the sand dunes 'sing', camels seek out water with the help of their herders and tiny swallows navigate across thousands of square miles to find a solitary oasis. This is a story of an apocalypse and how, when nature is overrun, some are forced to flee, some endure, but a few seize the opportunity to establish a new order.
