I think this is a really good starter book for those who didn't study the subject matter at hand.
However, for those of us who did, it seems pretty basic. I learned all of this from middle school through college and I don't know... I guess I was expecting something along the lines of Steve Jones' books, which always have those little known fascinating facts that even scientists feel wonder reading them.
Also, I was really expecting Nye to crack down on creationism, but he only does it for a very short length...
Still, this is a wonderful book for those who did not study evolution.
