Wisdom teeth are probably one of them.

Indeed.

And they're probably just a throwback to when we needed a full mouth of teeth, including the back, to chew on very difficult fibres.

And then there's the plica semilunaris.

Some people might say plica semilunaris.

So it's when you're gazing into your loved one's eyes and you see in the corner of their eye, you know, next to the nose, a little fold in the conjunctiva.

And that's exactly what it's the vestige of.

Yeah.

So maybe you've married a crocodile.

I mean, who knows?

Have you married a crocodile?

No.

No, no, if you look closely enough, some people do have that fold there, just to a different extent.

I think a lot of people do have the fold, it's just hard to see.

But some people, it encroaches a little bit on the eye.

So, yep, there's the picosemularis.

And then there are the ear muscles.

And very endearing.

So when you see somebody able to wiggle their ears, they're a vestige of a time gone by.

Yeah, danger territory when you start to think that something's vestigial.
