Just another thought on that: So you get "fooled" and attacked face to face from the back. It gets an eye or two. Now you turn around and stick it with a twig--killing it instantly. For the rest of your life, you go around with half your vision gone, vulnerable from the back--but definitely able to reproduce...

We aren't prey. We are hunters. To grow our brains bigger we had to trade other organ systems- in order to keep or BMI (body mass index) constant- so we traded our ancestors longer gut- adapted for vegetation- for a predators gut, adapted for meat.

It's a very cool story, and I like it a lot. Makes a lot more sense than some guy floating in the clouds. You might like The Wisdom of the Bones.

The eye thing isn't in there. But a predator mostly needs to see straight ahead, for tracking prey. Think about raptors, and felines, and canines- you just wouldn't use those eyes in the back of your head enough to make them a viable trade off. Plus I think there might be some real construction issues- when I think about the stability and structure of the skull.

I don't know whether things can be other than they are or not. We are probably in flux even now.

There IS such a thing as too much input. In Viet Nam, F-4 pilots turned off alarms when too many events were occurring and chose to deal with things by the seat of the pants. It's called sensory overload.

And I'll tell you that optical designs are always a trade-off for color correction, field of view, aberration and a variety of other factors. The eyeballs you have are pretty dang good by any standard for all that they do.

It's interesting that intelligence is linked to nearsightedness. Not 100% but you figure the tool makers need to have their depth of field to be adjusted. It is also interesting that nearsightedness is exacerbated by reading and other close up work. This is called adaptive optics.
