For over 40 million years forests have dominated the world. They have been the cradle of evolution for the mammals, but the world is changing. The forests are punctuated by open plains. With the constraints of living in the forest lifted, evolution has produced the largest land mammal that ever lived. She is an Indricothere and is about to give birth. After carrying her young inside her womb for two years, the moment has come to bring her calf into the world.
The mass extinction event that saw the demise of the dinosaurs was almost as devastating in the seas. The oceans were emptied of almost all large animals and carnivorous creatures, leaving them ripe for exploitation by new predators. 30 million years after the dinosaurs, the top of the ocean food chain is now occupied by an early whale: Basilosaurus. As on land, it's the mammals that have replaced the giant reptiles as the ultimate marine predators and none can now match the Basilosaurus.
For 160 million years dinosaurs have ruled the world, while mammals have lived in their shadow. Then a meteor crashes into the Earth wiping out the dinosaurs. 15 million years on, the world has changed. The sea level has risen and the temperature has reached an all time high. No animal has risen to take the place of the dinosaurs. Birds, reptiles, mammals and insects live together waiting to establish a new order. The film is about a Leptictidium, a highly successful mammal typical of this time.
