Natural Selection is a Designer of Sorts

Given enough time, evolution will come up with some pretty impressive designs. Most of the time though, it is pretty sloppy, just enough to get by. (This is how you know humans were not divinely designed.) You might wonder at my use of the term designs. Yes, evolution does design. It is quite stupid, about IQ (Intelligence Quotient) 1, but it is not just random. By analogy, your wife might learn to drive the family car, without any instruction, but just randomly pressing buttons and pedals, making small changes one at a time. Whenever the car drives better, she keeps that setting or pedal pressure. This is a considerably cleverer strategy than trying random combinations. Give her a decade and she will drive better than you.
