But basically, we don't know.

We don't know what they're sensing because not only are we sensing cold, we can sense sweetness.

We can sense pressure with our teeth.

Some people have sweet sensitivity.

So they just eat like a candy and they get some sensitivity from it.

I mean, you know, you felt like if you press really hard on your teeth, you can feel them.

So our teeth can sense multiple things.

The reason we sense cold is later.

Basically the signal gets sent out and how does it get decoded later?

Your brain says this signal means cold.

So that happens down the line.

That could technically be almost anything.

So I don't know if these early fish had this tissue basically, and then downstream they had it sensed for like, hey, it's warm water or cold water or a change in tides or something's trying to bite me or the sediment flow changed or any of that.

We don't know exactly what they're sensing, but we know that some kind of signal was getting passed.

This paper has been the nightmare of the past three years.

Checks out.

Yeah.

So it's an interesting story because it's a really winding pathway.

And I think it shows how science is not very linear.

And sometimes when we set out to research one thing or look for one thing, we get a much more complicated story, which tends to be a lot more interesting.
