    New to me at least. Ive seen it blamed on

    Loss of plentiful fruit habitat; forcing folks to hunt big game meaning throwing/coop battles become much more important and lots of cholesterol in the diet enabling fat wrinkles in teh brains

    Mushroom consumption giving rise to complex culture where big brains is teh sexy.

    Complex mouth parts enabled much more complex music making big brains teh sexy

    We is made in the image of god… So duh we is smart.

    Aliens.

      I’ve seen most of the explanations except for “lots of cholesterol in the diet enabling fat wrinkles in the brains.”

      One would think if that is the case then the brain of high cholesterol humans would be vastly more wrinkled than whatever the normal or lower cholesterol levels are. I’m not even sure how cholesterol would cause your brain to wrinkle. I’m assuming fat rolls=brain rolls in their minds.

        Yeah. I do know the brain has a bunch of cholesterol, but I’ve also read that none of it comes from eating cholesterol. Something about blood brain barrier preventing it from getting up there, and our bodies synthesize all of it, but I really dont know what I’m talking about here.

        This fermentation theory is a new fav of mine. I really think once we got in a position where culture can really take hold and art and family knowledge became both helpful with survival and sexually selected for, it was off to the races for making complex smarts. Brain size aint the only thing that matters either. There are many animals with larger brains than ours, but they aint been designing rockets or learning how to fold cool things out of paper or even painting portraits or making ink to write so-n-so’s got a big bum and I like it… What was I talking about?
