Anyone who has ever squirmed through a dental cleaning can tell you how sensitive teeth can be. This sensitivity gives important feedback about temperature, pressure—and yes, pain—as we bite and chew our food. However, the sensitive parts inside the hard enamel first evolved for something quite different.
Teeth first evolved as sensory tissue in the armored exoskeletons of ancient fish, fossil scans find.
thats right
Why do people do this? Not the first time I’ve seen someone comment the title of the post and nothing else. On Reddit, that would’ve been a sure sign that it was a GPT bot because that’s the kind of thing those bots do occasionally when they slip up.
I think it’s a reply to my incredulous “what?!”
Oooh, that actually makes sense lol. Guess I’m just slow.
Ehh. It took me a while, too, and I wrote it. Seriously though. What kind of sick evolutionary history is that? This is worse than the whole swim bladder thing. At least that doesn’t make me uncomfortable.
I beg your pardon
Swim bladders evolved from lungs. You wouldn’t think that something that makes the fishies better ocean divers originally evolved to let them breathe air.
its probably only a matter of time before that scourge arrives in our little internet hovel. most likely already happening.
What?
