It's theorized cooking kicked off our higher brain function evolution.

Since the body doesn't expend as much energy digesting food that energy could go elsewhere...that's the thought process behind it at any rate.

This seems like bullshit to me. Why would we develop the capacity for increased intelligence if we had no way of being able to use it? This is sort of like saying eating a very high calorie diet will make you more inteligent now.
