Scientist, Darwinian and atheist Richard Dawkins has written many books. They very quickly hit the bestseller list, thanks to his ability to translate complex scientific ideas into language the general reader can understand, without doing any violence to the science itself. His latest book The Greatest Show on Earth is his presentation of the evidence of evolution, from palaentology and embryology to genetics and geography.
