Query: Book is full of unnecessary bits and dumb bits

1)The bit about his love of hamsters as a kid was both unnecessary and dumb2)The fictional stories bit (last half of the book) was both dumb and unnecessary but mostly just dumb3) The bit on Anastasia was unnecessary4) The bit on the neanderthals was unnecessary (it's been pointed out, we already knew they weren't in our background, at least not much)5)The gripes with the other scientists was unnecessary6)The Polynesian DNA bit was unnecessary (and totally out of place)I could go on but I've made my point. Book is a total bummer.
