David Attenborough's First Life: Episode 2- "Conquest"

In the concluding part of the "Fist Life" series about the origin of life on Earth, David Attenborough's journey continues in Canada's Rocky Mountains, where fossils document an explosion in animal diversity never seen before or since. Traveling from there to North Africa, the rain forests of Australia and the east coast of Scotland, Attenborough discovers how animals evolved to conquer not only the oceans but also the land and air. © 2010 Atlantic Productions | BBC
