Let’s put it this way… the common ancestor of humans and chickens is way back, well before the dinosaurs. Their visual processing systems are on an entirely different, essentially unrelated vector from our own… so are their eyes. They can see in ultraviolet, for one, and you can’t, so they’re literally processing far more information than you can even perceive… comparing these two visual systems isn’t apples and oranges, it’s apples and orangutans. The point is to not underestimate what other brains are doing, just because they’re not familiar.
