A museum exhibit is getting ready to travel the country with an extremely controversial idea: evolution isn't perfect. Oh wait, that's a false controversial idea. Reality-based folks know it's not perfect. We have bad backs, ridiculously poorly designed organs, and a whole host of other problems because we haven't perfectly adapted to our environment yet. Genetic drift and pressures of environmental adaptation take a while, and we've only come out of our arboreal phase a few million years ago. Well, that, or because some chick gave some dude an apple. I can never keep all this "science" straight.
