"Professor Dawkins himself has a knack for the memorable metaphor. His great book The Selfish Gene is a case in point. People can be literally selfish, but not genes. Indeed Dawkins does not even think that there are genes for selfishness. Okay, he wrote: “The gene is the basic unit of selfishness.” But he didn’t really mean it. Not literally. The author of Genesis said that the universe was created in six days. But who would take that literally except some crazy fundamentalists? Oops – and Dawkins."
