Ologies with Alie Ward
Paleohistology (WHY TEETH EXIST) with Yara Haridy

And that makes sense that they look like odontodes.

Ologies with Alie Ward
Paleohistology (WHY TEETH EXIST) with Yara Haridy

I'm like, why does it make sense?

Ologies with Alie Ward
Paleohistology (WHY TEETH EXIST) with Yara Haridy

And he's like, well, because teeth are sensory.

Ologies with Alie Ward
Paleohistology (WHY TEETH EXIST) with Yara Haridy

Odontodes are probably sensory too.

Ologies with Alie Ward
Paleohistology (WHY TEETH EXIST) with Yara Haridy

And I was like, how do we prove this?

Ologies with Alie Ward
Paleohistology (WHY TEETH EXIST) with Yara Haridy

How do we actually test if odontodes, which are outside the mouth, are sensory the same way teeth inside the mouth are?

Ologies with Alie Ward
Paleohistology (WHY TEETH EXIST) with Yara Haridy

So, you know, your teeth are sensitive, right?

Ologies with Alie Ward
Paleohistology (WHY TEETH EXIST) with Yara Haridy

You're having some issues with that.

Ologies with Alie Ward
Paleohistology (WHY TEETH EXIST) with Yara Haridy

And like a lot of us do.

Ologies with Alie Ward
Paleohistology (WHY TEETH EXIST) with Yara Haridy

But it doesn't really make sense.

Ologies with Alie Ward
Paleohistology (WHY TEETH EXIST) with Yara Haridy

Why would you chew with these super sensitive structures?

Ologies with Alie Ward
Paleohistology (WHY TEETH EXIST) with Yara Haridy

Yeah.

Ologies with Alie Ward
Paleohistology (WHY TEETH EXIST) with Yara Haridy

That was always such a bizarre thought process.

Ologies with Alie Ward
Paleohistology (WHY TEETH EXIST) with Yara Haridy

But then you look at all these different animals that use their teeth as sensory organs.

Ologies with Alie Ward
Paleohistology (WHY TEETH EXIST) with Yara Haridy

Elephants touching the ground.

Ologies with Alie Ward
Paleohistology (WHY TEETH EXIST) with Yara Haridy

Narwhals with their giant horn.

Ologies with Alie Ward
Paleohistology (WHY TEETH EXIST) with Yara Haridy

It's not a horn.

Ologies with Alie Ward
Paleohistology (WHY TEETH EXIST) with Yara Haridy

It's actually a giant tooth.

Ologies with Alie Ward
Paleohistology (WHY TEETH EXIST) with Yara Haridy

Bonkers.

And they sense all kinds of temperature changes and wave changes because their dentine is sensitive.
