The Selfish Gene has been described as the most important book about evolutionary theory since Darwin. According to Dawkins theory of the selfish gene, natural selection does not take place on the level of the species or of the individual but rather among genes. Dawkins argues that human beings are programmed to preserve their selfish molecules, which are known as genes. Dawkins brilliant style shows that complex scientific ideas can be explained and made accessible to the general public, and that biology can be as exciting as an adventure story. Richard Dawkins is a renowned evolutionary biologist.
