Eating a raw food diet is a recipe for disaster if you're trying to boost your species' brainpower. That's because humans would have to spend more than 9 hours a day eating to get enough energy from unprocessed raw food alone to support our large brains, according to a new study that calculates the energetic costs of growing a bigger brain or body in primates. But our ancestors managed to get enough energy to grow brains that have three times as many neurons as those in apes such as gorillas, chimpanzees, and orangutans. How did they do it? They got cooking, according to a study published online today in the Proceedings of the National Academy of Sciences.

Robert Zwilling And today we got big brains which means we could figure out a way to manufacture enough of the correct type of food products that everyone needs to eat but somehow we still like to act like gorillas, chimpanzees, and orangutans. Wouldn't it be something if evolutionary progress was shaped like a bell curve.
