Cooking Stimulated Big Leap In Human Cognition

Hugh Pickens writes "For a long time, humans were pretty dumb, doing little but make 'the same very boring stone tools for almost 2 million years,' says Philipp Khaitovich of the Partner Institute for Computational Biology in Shanghai. Then, 150,000 years ago, our big brains suddenly got smart. We started innovating. We tried different materials. We started creating art and maybe even religion. To understand what caused the cognitive spurt, researchers examined chemical brain processes known to have changed in the past 200,000 years. Comparing apes and humans, they found the most robust differences were for processes involved in energy metabolism. The finding suggests that increased access to calories spurred our cognitive advances, although definitive claims of causation are premature. In most animals, the gut needs a lot of energy to grind out nourishment from food sources. But cooking, by breaking down fibers and making nutrients more readily available, is a way of processing food outside the body. Eating (mostly) cooked meals would have lessened the energy needs of our digestion systems, thereby freeing up calories for our brains. Today, humans have relatively small digestive systems and allocate around 20% of their total energy to the brain, compared to approximately 13% for non-human primates and 2-8% for other vertebrates. While other theories for the brain's cognitive spurt have not been ruled out, the finding sheds light on what made us, as Khaitovich put it, 'so strange compared to other animals.'"

      My brother made the mistake of ordering a steak "well done" at Peter Luger (probably the preeminent steakhouse in Brooklyn, NY). The waiter looked at him in disgust, and delayed the order 30 minutes. When they finally brought all the food out, the waiter said, "Sorry for the delay but we had to spoil a perfectly good piece of meat for this one." as they put the steak in front of my brother.

      If you ever get a chance to order multiple steaks in a steakhouse, I advise ordering one rare and one medium-rare. That will give you a good idea of the difference in texture and flavor the extra cooking does. As for well done... Let's just say you shouldn't order it in front of people you want to impress.

    Yep, yer darn right that cooking stimulates a big leap in human cognition. I can verify this from personal experience. First they see the pot of boiling water, and they're like, "What the hell?" You can see them start thinking real hard at that point. Of course, they're still not quite certain what's going to happen, but you can tell they're listening hard to what you're saying, and watching what you're doing, trying to figure it out for sure. There's so much cognition going on, you can practically see the sweat popping off of their foreheads. Eventually they really start to believe it, and usually then the cognition drops off due to panic. Beyond that point, they're mostly just shrieking and straining at their bonds and stuff. And of course once you put them in the pot, pretty soon there's no more cognition at all. I haven't RTFA, but I think the slashdot summary is probably a little inaccurate -- should be more like, "prospect of imminent cooking stimulates a big leap in human cognition."
