- alanthonyc 17y agoJust reading that article made me cringe. He may be right, but I couldn't finish it to be sure.
- ryanwaggoner 17y agoI couldn't even click on the link. Ugh.

- baddox 17y agoAnd he surmises that the sense of hearing evolved from the need to protect teeth. Seems that nerve endings in teeth would have been more likely to evolve.
- likpok 17y agoMore nerve endings in teeth mean it's harder to eat if you get decay or are eating something hard. Given the state of dental hygiene back in the day, it makes some sense.
- asdlfj2sd 17y agoAs good a theory as any. But: If I'm right, then ANY toothed animal is programmed to respond to it What about animals with teeth which regrow or continuously grow like rabbits?
- ars 17y ago"It's the sound of body damage; but it's a particular type of body damage for which there is no pain ...yet no healing." That's not actually true. Teeth do heal - which hurts his theory, except that while they do heal, they don't do it well, so there could be something to it.
