African penguins were once the most numerous sea bird on the continent--until their population was decimated by human activity. Visit a rare colony at South Africa's Boulders Beach and see how these master divers and ocean hunters are staging a remarkable revival.
The final episode deals with the evolution of the most widespread and dominant species on Earth: humans. The story begins in Africa, where, some 10 million years ago, apes descended from the trees and ventured out into the open grasslands in search of food. They slowly adapted to the habitat and grew in size. Their acute sense of vision led to them standing erect to spot predators, leaving their hands free to bear weapons. In addition, the primitive apemen also had stones that were chipped into cutting tools. Slowly, they grew taller and more upright, and their stone implements became ever more elaborate.
Professor Richard Fortey travels to northeastern China to see a fossil site known as the 'Dinosaur Pompeii' - a place that has yielded spectacular remains of feathered dinosaurs and rewritten the story of the origins of birds. Among the amazing finds he investigates are the feathered cousin of T-rex, a feathered dinosaur with strong parallels to living pandas and some of the most remarkable flying animals that have ever lived.
