Bigger brains through cooking

I read an interesting article today on Scientific American where Richard Wrangham theorizes that our brains evolved to become bigger because of our need to cook our food and our ability to use fire to do so. I know a lot of raw food advocates are probably upset about this article, but I thought it was an interesting insight into how humans evolved. Cooking food enabled easier digestion and liberated more calories. Our guts got smaller and our brains got bigger.
