You can't see anything because you're just looking at these, but where in real life, you're in a bush, you pretty much see the entire world outside of it. You can, you know, peek from outside of your bush. Oh yeah, that's interesting. So you had to keep shaking to get different shots than someone shoots you because they see you wiggling in the bush.

In real life, you're designed to be in these cluttery environments and to see perfectly well beyond that. Without having to move, too. Without having to move. And yes, you're losing what's behind you. But then you can start calculating how much of the environment can I see if I'm a forward-facing animal with this X-ray ability. That is, my eyes are bigger than the leaves.

Versus a rabbit, let's say, effectively, who has a full panoramic view. Yeah, he can see entirely behind him. But you can actually then calculate how much of the world outwards can you see. He's actually – I can see up to – if you think about it two-dimensionally, I can see up to – One, two, three, three and a half times better than him if you think about it as a two-dimensional grid.

But in fact, it's more of a three-dimensional grid. Then you have to sort of think about spheres, sphere packing problem. And so I can see only the front half of my little sphere is. But if the little – the world is sort of built out of these spheres of these little –

surrounded by lots of clutter, I can see the six spheres in front of me fully, and I can't see beyond that, and only half of mines, but I can see now six and a half times more of the, there's like simple models that you can build of simple models of forested kinds of environments where you can show that now you can see really almost an order of magnitude more. It's see the most.

It's not a little bit more stereoscopy here, but a little bit less seeing. No, it's just see the most. And so animals have, depending on their environment, they have more forward-facing eyes, the greater the extent to which they're in cluttered, forested kinds of environments.

And so one desideratum, see the most, suffices to explain all the variability that we find across mammals in terms of how forward-facing eyes work.
