It is estimated that 99 per cent of species have become extinct and there have been times when life's hold on Earth has been so precarious it seems it hangs on by a thread.

The Natural History Museum's Professor Richard Fortey discovers what allows the very few to carry on going - perhaps not for ever, but certainly far beyond the life expectancy of normal species. What makes a survivor when all around drop like flies? In this episode Professor Fortey focuses on a series of cataclysms over a million year period, 250 million years ago.

Narrated by Sir David Attenborough and from the award-winning team behind Planet Earth & Blue Planet comes the ultimate portrait of the earth's Polar regions. The Arctic and Antarctic remain the greatest wildernesses on Earth. The scale and beauty of the scenery and the sheer power of the elements – the weather, the ocean and the ice – is unmatched anywhere else on our planet. Yet these harsh environments are teeming with life: home to iconic animals from polar bears to emperor penguins and from killer whales to wandering albatrosses. Using the latest camera technology to film on land, from the air, underwater and below the ice caps, Frozen Planet follows their fascinating lives throughout the seasons as they struggle to survive. With spectacular polar landscapes and amazing animal behaviour, often filmed for the first time, it captures the drama of an extreme natural world. With both Poles under grave threat from climate change, this extraordinary series may be the last chance to witness these great wildernesses before they change forever.
