So here's one piece of evidence for why evolution shouldn't be taught in school. Not because it doesn't make sense, but because it has created horrific aberrations among the taxonomy of living creatures. Case and point: The Coconut Crab. It's the stuff of nightmares, kiddies. When a bottom feeding half-insect/half-shellfish with horribly tweaking antennae becomes large enough that it needs to a leash, it's time to pull a Sound of Thunder and go back to remove them from the evolutionary timeline.
