The book really is a fantastic read. If you've any curiosity on the matter, I would suggest picking up a copy. The premise is that it is not organisms, but genes themselves which are the primary target of evolution. All but the gene is mere trappings that surround their competitive replication. Those genes that manage to slide from generation to generation aren't doing nothing, they are those that are most successful at duplicating themselves into the next generation. If they do not hinder the organism in their duplication, there is no pressure for their removal.
