Great book, yes, but don't stop there. There is a lot more to evolution than Dawkins suggests; selection, no matter the mechanism, is, after all, determined by phenotype (the "realised organism", if you will) rather than genotype. And there are a lot of models of selection (and of modification) that make accurate predictions but don't have the Dawkins seal of approval. You'd be missing a lot if you allow yourself to become stuck in the notions of 1976, no matter what their merits at the time.
