How do creationists account for vestigial organs?  Wings on an ostrich, eyes on blind fish/moles, the arm/leg bone structure in whales.  The tailbone, wisdom teeth, and (the all-time favorite) the appendix in humans.  Extra parts and spare organs seem an odd design for a divine creater, especially an omnipotent one, and there are numerous examples throughout nature.  Evolution neatly ties up such loose ends, can creationism?
