I’m not arguing good vision is not important for general survival, but I think hunting has a higher ceiling of usefulness for good vision than anything else humans did in that period

I would argue there that there’s a limit to how much better eyesight would affect things like that though, falling over and dying

Using that example if someone’s vision is like an old CRT they might not see a root or something, trip over and die. If they have 1920x1080 they might see it if they have 4k they definitely see it.

Hunting however can benefit limitlessly, the further away you can see the better you can track

Not sure what your mean by it doesn’t work that way

If men were predominantly doing the hunting, women would be more likely to choose a more successful hunter (more likely to pass on their genes if they have a better mate)

Also in general the ones who were better at hunting and their mates would be more likely to survive long enough to have children
