Human Errors: A Panorama of Our Glitches, From Pointless Bones to Broken Genes | 
Around 6% of males have some form of color blindness. It's not nearly as common in females because the screwed-up genes that lead to colorblindness are almost always recessive and on the X chromosone. Because females have 2 X chromosones, they have a backup if they inherit one bum copy. With 7 billion people on earth, that means at least a quarter of a billion people can't appreciate the same pallet of colors That's almost the entire US population
pickI always thought of the human body as a “beautiful machine.” Oh wow was I ever wrong between all of our junk DNA and useless parts among other things. At least I had a lot of fun while listening to how imperfect we humans really are!

pickA Pick with reservations. The part about the weird physical aspects of the human body worked much better than the part that talked about the weirdness of the brain. If you want a weird brain book, read The Idiot Brain, by Dean Burnett, instead.
