So just what is this thing called "evolution?" Everyone has heard of it, but what actually is it? What does it say? Where did it come from? What does it mean? Why do scientists accept it as valid? The books listed on this page will (I hope) help you answer these questions.
Because of the way I got interested in the subject, my approach to studying evolution is sort of like the Blind Men and the Elephant in that no one of these books will give you the whole story, but when you put them all together I think you'll have a pretty good mental image of the theory and what it says. And also what it doesn't say, which in some ways is just as important.
