An interesting report in the NYT about researchers who set up experiments with chimpanzees that showed that they would postpone eating raw food in order to take it to a simulated oven and cook it before eating it. The chimps put the raw food in a container which was surreptitiously switched to one with the food already cooked which they preferred. This showed instrumental behavior and impulse control not to mention a good palate. Here is the link: http://www.nytimes.com/2015/06/03/us/chimps-can-cook-a-mean-potato-research-says.html?hpw&rref=science&action=click&pgtype=Homepage&module=well-region®ion=bottom-well&WT.nav=bottom-well
Another scientist, Richard Wrangham, a few years ago made a convincing albeit circumstantial case that cooking food was indeed an important innovation that enabled our brains to grow and become the energy hogs they are, beginning around 2 million years ago. I like it and posted here about it in connection with Michael Pollan’s book, Cooked, on 8/4/14. Let’s eat.
