It does. all over the world. one example, our ancestors used to all have Wisdom teeth because our jaws were muuuch bigger then. as our ancestors ate better / softer food the use of wisdom teeth vanished, so our jaws got smaller. now we cant even fit wisdom teeth, they have to be removed because they make your other teeth go all crooked and it is very painful. and now not everyone even gets wisdom teeth... evolution in progress.. it is slowly removing wisdom teeth once and for all

dont forget we have body parts that other animals have but we have absolutely 0 need for them but they are used by other animals...


and humans have a tailbone... our early early ancestors had tails.. but as time went on we lost them. EVOLUTION
