Yeah, but it's also a massive compromise, which is the bit that people always miss.

It's Darwin's line.

It's descent with modification.

Yes, over time you can end up with extraordinarily weird things, but mostly what's happening is you're changing something fairly simple.

You're making edits to the existing plan, which is why you don't have animals with tentacles.

They have legs, which have joints, which have fingers, and they all have one bone, then two bones, then a bunch of little blocky bones, and then a few more, and then the little ones that make up the digits for hands and feet.

Basically everything has that.

because you're modifying that pattern.

And occasionally we had something weird, like, um, most of the modern lung fish have basically reduced those down to, well, they, they had a more simple plan to begin with, but reduce it down to a stump.

And then they've got something like a flailing tentacle.

But,

Yeah, you know, snakes have got rid of them or the various legless lizards and things like that.

And again, Sicilians and all the rest.

But yeah, you're subtly changing certain things in certain ways is mostly what's going on.

And then those build up over time.

But also against that compromise of there's things that do and don't work.

There's things that are interlinked.

And so you can't modify A without modifying B.

modifying a will kill you therefore b never modifies because the two are genetically linked in some way or yeah like the compromise of the lion's mane making it darker makes you sexier but more likely to kill you you you i think people think evolution is like perfecting things in some way and they're not they're bodge jobs you know that's why we have a blind spot in our eye but

things like squid don't.
