    It’s a thing that’s being studied but apparently it’s also true for reindeer which turn their eyes blue during the winter to help them see better in low light conditions and brown in the summer when there’s better lighting.

      Ha, man, I thought I was crazy, I had no idea. My ancestry was largely from northern Europe - but my Dad did a lot of astronomy and typically had me find things for him when we were out in the field. He always said “because you see things better than me” which I thought was absolute horseshit because I’m near sighted and he’s farsighted.

      Maybe I did because my blue eyes actually helped a bit.

        Definitely a possibility. All life on earth is actually insane in how it works and why. Even the simple looking things like the color of our eyes.

      Its basically also why people closer to the equator have darker skin.

      • Too much sun = skin cancer
      • Too little sun = vitamin D deficiency
      • Too little melatonin = skin cancer prone skin
      • Too much melatonin = needs vitamin D supplements in the Arctic winter.

        Yep and by that same logic the ubermensh are actually gonna be the ‘inferior’ (not that I believe any of that) species with the climate change that same people love to deny.
