I recently found out why the human brain has all those wrinkles. I always just assumed that was what brains look like.
Then I was shown a rat brain. And other animal brains. They were completely smooth.
So why the wrinkles? Because there are extra ridges needed, extra space basically, to fit all the learning on there. That skull is pretty tough, and it doesn’t expand well Leader-style. So the way all the stuff fits on the brain is by having it expand without growing outward by adding extra area within the same sphere. There’s room in there for more. Fill-er up. Learn. God will make more space to fit it in there.
