A succession of extraordinary creatures has since come and gone, leading to our own ancestors, and yet we know virtually nothing about them. These bizarre beasts were some of the most fascinating creatures ever to have inhabited our planet. The award-winning team that brought us Walking With Dinosaurs now explores the rise of the mammals. The latest scientific findings, advanced computer graphics and strong natural history stories are combined as we return to the sights and sounds of extinct worlds - this time full of life you hardly knew existed. Walking With Beasts takes you on a journey through time to distant worlds: from the hottest, wettest climate the earth has ever known to one of the coldest - the Ice Age. See the early forerunners of the whale (walking!), avoid the carnivorous pig the size of a rhino, and pity the horse the size of a cat, eaten by a bird the height of a man! And we humans are not safe either - mighty sabre-toothed cats with teeth the size of carving knives have a taste for our own ancestors!
