All living things need to eat, but only humans cook...and how we cook has evolved and grown more sophisticated since our earliest days. We have nonstick skillets, automatic espresso machines, digital meat thermometers, and high-speed blenders. But in our earliest days, we didn't even have pots to cook in.
