Food for thought

Apparently, chimpanzees get the Maillard reaction and other chemical changes that take place when food is cooked and made tastier in the process. At least that is an assumption one might read into research that shows chimps, when given a choice, will opt for a cooked sweet potato rather than the raw vegetable. Moreover, the chimps will observe the "cooking" process happening and opt for the cooked food each time as well as placing pieces of raw sweet potato into the receptacle that "cooked" the food in the initial experiments. The researchers allude to the cognitive ability to enjoy cooked food rather than raw as being associated with the common ancestor of chimps and humans and emerging early in our evolution when we learned to control fire to actually learn cookery skills.
