How Dawkins explains the theory of evolution is very original. He defended a surprising and highly relevant perspective: these are the genes that are our "creators". This means that the human being is only a "" single shell "" for our genes to move and reproduce. Almost everything is explained in detail and without any formula or complex definitions. However some of its developments as examples of species according to their rate of success and extinction are quite harsh and repetitive. But everything else is, in my opinion, essential for anyone interested in biology and evolution.
