Meanwhile, he says, if you’re the kind of animal that gets hunted, “you’re very likely to have a horizontal pupil” and to have your eyes on the side of your head. That makes sense, he says, because it gives prey animals a panoramic view, so they can best scan all directions for danger.

But then the scientists began to wonder. This trick would only work if the animal’s pupils were parallel with the horizon. And creatures like horses and sheep are constantly pitching their heads down to graze. When the researchers went to watch the animals in action, they discovered something unexpected.

“When they pitch their head down, their eyes rotate in the head to maintain parallelism with the ground,” says Banks. “And that’s kind of remarkable, because the eyes have to spin in opposite directions in the head.”

Veo 3 refuses to do photorealistic eyes, it’s over. Gotta love big corpo.
