While dogs are said to share more than 99 per cent of their DNA with grey wolves, recent research has indicated that this link might actually be the key to why dogs have become the perfect family pet.

Life and Death explores the impact of Darwin’s ideas on our understanding of the meaning of extinction and the interconnections between all life on earth and the environment. Darwin learned many lessons from the giant fossils of extinct animals he found in Argentina and Chile. He eventually revealed to us the unpalatable truth that the logical conclusion to evolution is not perfection but extinction. The extinction of one species creates an environmental niche for new species to fill. Darwin’s theory also gives us vital knowledge we can use to help prolong the existence of our species by respecting the interconnections between all elements of the natural world and the environment. It’s a story in which Darwin’s ideas are taken up with great enthusiasm by his followers throughout the 20th century. But humanity misses one opportunity after another to acknowledge and reduce its destructive impact on the planet. As a result we have set in motion the sixth mass extinction of life on earth. And we are running out of time to do something about it by preserving ecological "hotspots" like certain rainforests which are some of the most productive cradles of evolution. This programme is a warning, but also a celebration, of the knowledge Charles Darwin gave us in his theory of evolution. It confirms that Darwin’s theory continues to inform our understanding of ourselves, our planet and the intricate interconnections between all life on earth.

David Attenborough narrates the intimate story of a leopard mother and her two cubs. This very special family must survive in the wilds of Botswana alongside some less-than-friendly neighbours: lions, wild dogs and hyenas. The competition for food is tough, and if they are going to make it they must learn a new skill - they must learn to fish. This is an epic family drama. With them every step of the way is local cameraman Brad Bestelink. Brad's 18-month journey following the lives of these secretive big cats offers a rare glimpse into an otherwise hidden world.

Megafauna such as humpback whales and orca, massive seals and stately penguins all take the brutal conditions head on and thrive in this year on ice.

Attenborough describes the course the Amazon, starting high up in the Andes of Peru, whose streams flow into the great river. Young rivers are by nature vigorous and dangerous: they flow fast and form rapids, thick with mud and sediment.
