Book of the day: "Six Impossible Things Before Breakfast" by Lewis Wolpert.
Ok, I really wanted to like it, since the subject matter is interesting. But in the end, I think it was too light on the science. The most interesting parts were when Wolpert talks about human mental development or about the various odd belief systems of tribes, but both of those were really not very deep. They were there to explain the arguments, nothing more.
End result: it didn't really grab me. It wasn't bad, but it also wasn't terribly intriguing.
