On the most recent episode of The List Show by Mental Floss, host John Green provides a hefty list of all the wonderful things about pigs, including their personality, their history, their bravery, and their incredibly keen intelligence.
More about how smart pigs are. In a study conducted at Penn State, researchers found that pigs were able to learn to play a video game faster than chimpanzees. Dogs were not able to figure out how to play it at all. Pigs can also use mirrors. In a 2009 study published in the Journal of Animal Behavior, researchers prove the pigs can use a mirror to find hidden food. It’s possible that this shows them as being self-aware and intelligent as apes and dolphins.
