Bats who see in color and much more
While I did find myself feeling the sense of awe and intellectual stimulation that I get from good science writing in many of this books pages, it wasn't the instant page-turner of a book like 'The Selfish Gene'. In fact I read this book right after the aforementioned book. The Selfish Gene is a hard book to live up to. Having said that, some sections of this book give you that sense of awe at the biological world that Dr. Dawkins is so good at presenting. Reading passages of this book to some of my scientist, but sadly religious friends around the campfire, found them quite interested as well.
