The Selfish Gene

Before I forget, let's mention Richard Dawkins' The Selfish Gene. Very well written and has some interesting ideas about how in tribal societies people want to favour some relatives that "are most likely to carry" genes similar to theirs. Contains a good explanation of the Prisoner's Dilemma, too. I read the second edition and Dawking mentions in the foreword that based on the feedback of the first, he thinks many people did not get the meaning of "selfish" right. Unfortunately I find Dawkins himself is not too clear about it. On the other hand he uses it like a technical term but in a passage quite late in the book laments that the humankind has not gotten rid of this imposed selfishness. Actually, Dawkins in not too clear about the definition of "gene" either.
