I successfully resisted the temptation to title this post "Monkey see, monkey do."

In Ars Technica (which did not resist that temptation, you will note if you click through to the article):

Empathy isn’t only limited to humans. The chimpanzee and many of our other primate relatives are fully capable of processing complex emotions and behaviors. Chimps can also learn new abilities by watching their peers' actions and copying them. Matthew Campbell, a post-doctoral fellow at Emory University who studies primate behavior, and his colleagues wanted to see whether chimps identify with computer animations the same way they do with expressions from real-life animals. The (perhaps) surprising answer: yes, they do.
