Agriculture is what made our brains shrunk. When you can stay in one place and provide for yourself, you don’t need to remember topography or weather patterns like you do as a nomadic hunter.

Yes, not that agriculture itself didn’t make people dumb, but the more consistent availability of calories allow for specialization and trades. In essence “civilization” as we know it is about collective specialization. You give up jack-of-all-trades for laborers, artisans and professionals. They still need to use their cerebral cortex, but once they have their jobs down pat, I’m going to bet their EEG readings flatten out a lot.
And you are feeding yourself with crap like grains instead of the fats from animals that grew our brains in the first place.
