In relationship to function at the top. And so they're throwing out the very thing that allows you to understand, even if they are only interested in mechanisms, which my eyes glaze over with mechanisms, you can't understand mechanisms without inherently understanding the functions.

Well, I mean, ecological, capital E, ecological perception, ecological vision with Gibson ended up biting onto a whole lot of philosophical baggage that I never bought into. I consider myself a lowercase e, ecological vision person, in which case you can't understand what vision or anything.

Horny mechanisms are doing it unless you understand what it was functioning for in the natural environment for all of those millions of years. And so let me just give you some specific examples. So one of the things that I had noticed was that people had talked about color for 100 years and color vision. First of all, to back up, we primates, we and some other primates, have a third dimension.

Your dog just has gray scale. And yellow-blue, two dimensions. All the bunny rabbits, horses, just have two dimensions. But some of us primates have a third dimension, red-green. And so for 100 years, they thought, well, maybe it has something to do with finding fruits in the forest. And there was never any good evidence for this at all.

There's incredible varieties and variability in terms of the kinds of diets that they would have.

not to mention just even generation to generation is going to experience radically different kinds of diets of fruits but they all have the same um pegged the exact same um kind of color vision and it's a weird this is across primate groups across all trichromate primate groups all the old world uh trichromats have so dog um dogs and bunny rabbits have one low wavelength sensitive cone down in the 550s and then the other one um sorry um in the in the 400s 450s or so and that's sort of the

blue cone and then the other ones we have one in the 550s or so for the dogs that's around here so you've got two and then what you'd expect if you're going to have a third one would be that suddenly it may be over here you'd have the uniformly distributed like rgb for your cameras they're uniformly distributed across the spectrum which is sort of a poor man's spectrometer you've got three across the spectrum you put them uniformly but in fact ours is this

we ended up with another cone sensitivity right next to the other one. They're exactly side by side in a really weird, peculiar way. Why would you want to have a third cone sensitivity the same part of the spectrum? It's just like 15 nanometers away.
