The Genius of Charles Darwin, Part 1: Life, Darwin & Everything

In the first part of the series, Richard Dawkins retraces Darwin's journey as a scientist. He re-examines the rich evidence of the natural world – iguanas on the Galapagos islands, giant fossilized sloths in the Americas and even pigeons back home in England – which opened Darwin's eyes to the extraordinary truth that all living things must be related and had evolved from a common ancestor.
