Men Aren't Sheep, They are Cows

So it seems that in the last 5000 years homo-sapiens have lost about 10% of their brain size, what part of the brain is not so easy to determine. But skull sizes have been shrinking and the brain with it. It was just before that that we began the hard switch to grains as a primary food source.

So at last, the long, careful plan of the cow has come to fruition. First, show us how calm and quiet eating grass is. Then show us how much more grass than cows there is; we breed more, make more of us and then become dependent on grains/grass. Once hooked we begin to shrink, they follow that up with some mad-cow disease and we abandon meat and our brains shrink then we become the cattle!!
