TIL: males have 25% more neurons in the visual cortex than females - eviltoast

The eyes have it: Men do see things differently to women

The way that the visual centers of men and women’s brains works is different, finds new research published in BioMed Central’s open access journal Biology of Sex Differences. Men have greater sensitivity to fine detail and rapidly moving stimuli, but women are better at discriminating between colors.

    it’s essentially an excessive over simplification of something that’s not perfectly accurate, that’s the problem.

    While it would apply to hunting, when you’re talking about something like visual acuity, it’s super broad in the applications that it’s useful in. Even things such as not falling over would be beneficially influenced by better visual acuity. You could argue that men just stopped falling over and dying as frequently, leading to evolutionary selection over time, but that’s probably not super accurate lol.

      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

        that specific example was a little bit hyperbolic, but i think there is likely a general improvement with the ability to sight vision and small discrepancies in things.

        Also you’re talking about visual clarity, this is specifically about being able to detect motion better.

        as for why this matters for shit like not falling over and dying? Well cool little story, sometimes humans like to move around. Things around us move in relation to ourselves, so it could be expected to see some benefit in that regard as well.

          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
