Pigs aren’t actually as stupid as nursery rhymes make them out to be. Sure, they spend most of their free time wallowing in their own droppings, but something’s definitely going on inside their tickled pink heads. Researchers have found that they can respond to a given name within a week of birth. Could you do that when you were 1 week old?
Additionally, when researchers compared the results of pigs and human toddlers in a joystick-controlled video came involving object recognition and manipulation, pigs consistently left the toddlers in the dust. Pigs constantly demonstrate theory of mind-that is, the ability to understand what other animals are thinking or desiring. Some human beings could learn a thing or two from them.
