What I love about this is that the ocean seems completely featureless to us.
The open ocean is just this flat landscape.
It's two-dimensional.
It looks kind of boring.
That is what it looks like to our eyes, but to the nose of an albatross foraging over the ocean, it's very three-dimensional.
It has these mountains and valleys of DMS and other scents.
that give the bird an idea of what's going on beneath the surface of the water.
It's not flat, it's not featureless, and it only is that way to our umwelt, but not those of a bird like an albatross.
That's right.
The beta test pyramids before we landed on this deluxe model.
Right.
Yeah, you absolutely do.
And, you know, Darwin can relax.
We have it sorted.
So, yeah, there are actually animals with every possible degree of eye.
The simplest eye really is just a single photoreceptor.
So it's a single cell that is sensitive to light, where light...
light triggers a chemical change in the cell which leads to an electrical signal being sent and that cell can detect the presence of light.
Once you're sensitive to light, once you can detect it, then you can add things like a little bit of pigment.
If you have pigment on one side, it creates shade and now you can not only detect light but work out where it's coming from.
