Sorry, wasn't able to edit my above post, so please allow me to make a succinct caveat to my above post: Also, Richard Dawkins happens to be an amazing writer on the subject of evolution. I'm not going to comment on his atheistic God Delusion book, but if you actually read works like The Selfish Gene or The Ancestors Tale, I can't imagine how someone couldn't not only be impressed by the skillful manner in which he writes (almost poetic), but also be persuaded into accepting evolutionary theory. Those that don't accept it, I'm just curious where you got your PHD in evolutionary biology? You may THINK you understand it, but do you really? A great book to start with would actually be Dawkins' "The Greatest Show On Earth" which is a guide through the evidence and the reason why 99.999% of biologists accept it as fact. He shows his masterful teacher skills by raising questions and letting you come to your own conclusions, not by telling you how to think. A great companion piece is Jerry Coyne's "Why Evolution Is True". Those books, among many others, changed my life. And I really hope none of these words come across as invidious. Thank you.
