'The Cooking Ape' Response

Wrangham discusses in this interview the links between our primitive ancestors and humans today, and how cooking and eating has evolved along with ourselves- ie the harnessing of fire power, our teeth and facial structure, etc. He says that cooking and meat eating are the two proposals for what transformed ape into human, aka what we are today.  Once we learned to harness fire, we could cook our meat instead of eating it raw, making it easier to eat.  Our food became more digestible, and we ate fewer calories, and our bodies became slightly smaller.  Changes in the food supply also changed how and what primates ate, according to Wrangham.  Foe example, chimpanzees must have fruit to survive, and gorillas don't need it. That effects how each looks and behaves. These are the main points Wrangham lays out to evidence his claim that cooking played a large part in the evolution of apes to humans.
