I think it's very interesting to know that this theory is a continuation of the evolution of Darwin. Richard Dawkins goes further in the analysis, we no longer speak of the species as such, but the genes that compose it. The basics are quickly installed, the rest of the book appears to be based on the examples to reinforce this theory. I'm that has a little more than half, one little bored at times but I want to emphasize that this work still remains suitable for all, the author made sure not to waste reading and regularly sets technical concepts, it is appreciable. Another tip, I think it's important that I understand what the principle of "natural selection" before reading this book, why I recommend reading "Darwin, the origin of species."
