Over 60,000 years ago, the first modern humans left their African homeland and entered Europe, then a bleak and inhospitable continent in the grip of the Ice Age.

So what happened when the first modern humans encountered the Neanderthals? Did they make love or war?

Woolly Mammoth: Secrets from the Ice is a documentary presented by English anatomist Dr. Alice Roberts that reveals some of the secrets of one of the most widely known extinct animals ever. Humans have been transfixed by the Wolly Mammoth since the end of the last ice age when there were still herds of them roaming the continents of Asia and Europe. Despite many people knowing about the great Woolly Mammoth until recently very little was known about them despite ancient humans living along side them for so long; few documented accounts exist.

During the last Ice Age, millions of large animals roamed the Earth, from wooly mammoths and giant sloths to cave lions and saber-toothed cats. But as the temperatures rose, three-quarters of these species died out. What happened? Can environmental changes alone really explain this mass extinction, or did humans - who at this very time were beginning their conquest of the planet - play a key role? To find out, researchers around the world are hunting and studying fossils in their search for answers to solve the mystery of the Ice Age giants.
