PAX6

Another example is in eye evolution in animals.

There's this master eye gene called PAX6- And what they found is that transposons basically interact with this gene that's really involved with eye development, and there's a accumulating collection of regulatory switches that's built on this PAX6 template that generates an eye, but it allows for tweaking.

It allows for different types of eyes to evolve, like the different types of eyes you see in arthropods, like insects or in fish, or in mollusks like squid and octopus and stuff.

It's this ability to add layers of complexity onto an existing template as a theme that keeps coming up with transposons.

You don't have an iris or you have a little bit of an iris.

But as I said, that is the disease and it's PAX6 gene.

It is.

Yep.
