Watch part two

Outspoken evolutionary biologist and best-selling author, Richard Dawkins explains how he became a passionate advocate for the theory of evolution.

Professor Richard Dawkins created a stir with his first book, The Selfish Gene, in 1976, and went on to generate more controversy 30 years later with the international best-seller, The God Delusion.

His most recent book is written for 12 year olds. Its aim? To inspire young people with the same excitement for science that he feels.

The renowned evolutionary biologist talks to Riz Khan about his early years as a boy in colonial Africa, how he came to question the teachings of the Church, and embrace the work of the ground-breaking 19th century English naturalist, Charles Darwin.

Never fearing being too outspoken, Richard Dawkins is considered one of the world's leading figures in the debate on evolution versus creation.
