It's death on an unimaginable scale, when a majority of Earth's species quickly die out. It's called "mass extinction," and it's happened at least five times before. Cataclysms, such as supervolcanoes or asteroids, are thought to cause these events, but some experts believe a man-made mass extinction could be next. Is our planet in trouble? And if so, is there anything we can do to stop the next catastrophic annihilation? Experts are traveling the world, performing groundbreaking scientific detective work to answer these very questions.
Adam Rutherford meets a new creature created by American scientists - the spider-goat. It is part goat, part spider, and its milk can be used to create artificial spider's web. It is part of a new field of research, synthetic biology, with a radical aim: to break down nature into spare parts so that we can rebuild it however we please.
The British back garden is a familiar setting, but underneath the peonies and petunias is a much wilder hidden world, a miniature Serengeti, with beauty and brutality in equal measure. Chris Packham and a team of wildlife experts spend an entire year exploring every inch of a series of interlinked back gardens in Welwyn Garden City. They want to answer a fundamental question: how much wildlife lives beyond our back doors? How good for wildlife is the great British garden? Through all four seasons, Chris reveals a stranger side to some of our more familiar garden residents. In summer he meets a very modern family of foxes - with a single dad in charge - and finds that a single fox litter can have up to five different fathers. In winter he shows that a robin's red breast is actually war paint. And finally, in spring he finds a boiling ball of frisky frogs in a once-in-a-year mating frenzy. The secret lives of the gardens' smallest residents are even weirder. The team finds male crickets that bribe females with food during sex, spiders that change colour to help catch prey, and life-and-death battles going on under our noses in the compost heap. So how many different species call our gardens home? How well do our gardens support wildlife? By the end of the year, with the help of a crack team from London's Natural History Museum and some of the country's top naturalists, Chris will find out. He'll also discover which type of garden attracts the most wildlife. The results are not what you might expect... You'll never look at your garden in quite the same way again.

The wild dogs of Luangwa Valley are organized, tenacious and strictly hierarchical under the leadership of an alpha pair. While cheetahs sprint and lions ambush, wild dogs rely on their stamina to wear prey out, sometimes running up to 20 miles at a time. But to maintain dominance, they'll need to train their youngest members to hunt effectively as part of the pack-and time is running out.
David Attenborough takes a breathtaking journey through the vast and diverse continent of Africa as it has never been seen before. (Part 2: Savannah) East Africa is a land which is constantly changing. To survive here, creatures must be able to deal with unpredictable twists and turns - wet turning to dry, feast to famine, cold to hot - no matter how hostile it becomes. From dense forests to snow capped peaks, steamy swamps and endless savannah, this unique and varied land is also a haven for life, supporting large animals in numbers found nowhere else on Earth. But away from the familiar, forever-travelling herds, there are a huge cast of other characters - lizards that steal flies from the faces of lions, vast dinosaur-like birds who stalk catfish through huge wetlands, and an eagle who risks everything on the arrival of ten million bats from a far off rainforest.
