Since most of the organs of the body are paired, you might have taken your two eyes for granted. If you stop to think about possible reasons, you might decide that with two eyes you can get a wider field of view to the sides. True enough. But to have a really terrific field of view, wouldn’t you design the system to have one eye mounted on a finger-like stalk atop your head to see all around? Wouldn’t it be nice to have the ability to see behind your back? The way it is now, there has to be a elaborate neck joint complex so that you can turn your head to get a reasonable near-360 degree panorama. Yet, nature evolved into our present set-up. Why?
