Is cooking the key to human evolution?

There is a new book out that provides a scientific argument that the evolution of the human brain into the wondrous thing it is today hinged on the idea that one of our ancient ancestors had to actually cook food before eating it. According to this argument, cooking food began the process of breaking down the food, allowing for early humans to have smaller digestive tracts, expend less energy on digestion, and get more nutrition from the food they ate. The argument can also be applied to descredit the modern raw food movement. What do you think?
