There are some good examples in this book, in addition to some good science-fiction scenarios that were enjoyable and original, but I found it hurrying from topic to topic without much depth. There's nothing special here that can't be found in Dawkins' other book. If you still didn't read The Blind Watchmaker, or better still The Ancestor's Tale, I would suggest you opt for them as the topics he is talking about in this book are better treated in in the others and in the case of The Ancestor's Tale, they are more up to date.
