I can think of even more ways we benefit from having two eyes, like not having to whip your head back and forth if you want to scan the landscape.

But if they were mainly for redundancy the eyes might be closer together, like the nostrils (and unlike ears, which help with spatial awareness).

I think the fact that modern life requires less and less depth perception (when’s the last time you had to judge how far to throw a spear, etc) might be leading us astray here.
