In the frozen wilderness of Antarctica, where oceans ice over and just staying alive is an achievement, one creature has perfected the art of survival - the emperor penguin. Eons of evolution have built an animal superbly adapted to the howling gales and sub-zero temperatures, but the emperor may have finally met its match. Parts of Antarctica are warming, giving birth to huge icebergs, and the consequences could be catastrophic for this majestic animal. In a place where all life is touched by the ice, it is a dramatic shift. Explore this region from its inhabitant's perspective, using state-of-the-art technology. By better understanding these amazing animals, researchers can help prepare for their future, as the balance of life in the Antarctic continues to change.

This programme surveys mammal herbivores and their predators. The herbivores began to populate the forests when the dinosaurs disappeared, and many took to gathering food at night. To prepare for winter, some store it in vast quantities, some hibernate and others make do as best they can. However, the carnivores joined them, and when a drying climate triggered the spread of grass, they followed their prey out on to the plains. Grass is not easily digestible and most animals that eat it have to regurgitate it and chew the cud. Out in the open, the leaf-eaters had to develop means of protection.

We can all trace our lives back to a beginning. But what defines the beginning? Is it the moment when two cells unite? Or does something have to know it is alive before its life can begin?

Developed over centuries, coral reefs house fragile ecosystems, but they too have to fight to survive.

Even after thousands of years of ice crushing the northern hemisphere and temperatures of 20 degrees lower than those of today, many of the great giants of the ice age still walked the earth. It was only when the world had warmed up again that mammoths, woolly rhinos, sabre-toothed cats, giant ground sloths and glyptodonts finally became extinct. Professor Alice Roberts sets off on her last voyage back to the Ice Age to discover why.

How air-breathing mammals have found remarkable ways to overcome the many challenges of a life in water, from freshwater jungle ponds to the dark depths of the open ocean. Featuring footage of the birth of a huge sperm whale calf, never-before-filmed orca hunting behaviour, and coastal coyotes in Mexico that have learnt they can benefit from the daily offerings washed up on the shore with each new tide.
