You need teeth. Nerves preserve teeth.

  • If teeth had no nerves, you'd chomp on unchompable things -- "me eat rock" -- until your teeth wore down, broke, and fell out. Then you'd die and not have children whose teeth have no nerves.
  • If your teeth have nerves, you're a bit more careful about your teeth -- "ow, me NO eat rock" -- and you live a healthy life and get laid and have children whose teeth have nerves.

Take care of your teeth and you'll get laid. So many still don't understand this concept.

Some understand the concept of it (and general hygiene) up until they get laid a few times by one person, then stop because they’ve achieved the goal of relationship. Then wonder they don’t get laid anymore.

This is the best plain language explanation of natural selection and evolution I've ever seen, I want ALL of them to be in this format.

Myeah, but then the problem is that such expansions would often be oversimplified.

Do we know if this is still true in species like crocodiles that freely lose/regrow teeth?
