Query: good concept, not for scientists

I was worried when the introduction tactfully implied that the author was playing fast and loose with the facts. Was that the best person they could get?! Then, I was just plain bored. It wasn't bad as a history lesson, but that's not why I bought the book. Perhaps the fact that I do have a medical background made me more skeptical. I expected to find more than unfounded speculation. I would suggest only reading this book if you did not take any biology classes after you left high school.
