Jim Watters pointed out to me that I didn't set this poll up to allow voters to change their votes. I've fixed this problem, so now you guys can change your votes at any time up until the poll ends. Thanks, Jim!

LevV, I too have read and enjoyed Carl Zimmer's, "Evolution: The Triumph of an Idea." It's definitely the best book on evolution I've read.

I'm closing this poll right now, and How the World Really Works: The Science Behind How We Got Here and Where We're Going will be our new non-fiction book.
