Any book with a subsection called "The Second Coming of the Trichromatic Monkeys" is bound to be good. And this book was no disappointment. After reading a number of evolution books over a long period it was exciting to read a completely new set of ideas and evidence based on actual gene sequences. The focus on opsins and color vision was a useful antidote to some of the "just so" stories you occasionally read in evolution books.

I could have done without the chapter on why intelligent design is wrong, it seems like a waste of a good scientists time to bother to write about this topic.
