Animals are smart

How do you give a chimp—or an elephant or an octopus or a horse—an IQ test? It may sound like the setup to a joke, but it is actually one of the thorniest questions facing science today. Over the past decade, researchers on animal cognition have come up with some ingenious solutions to the testing problem. Their findings have started to upend a view of humankind's unique place in the universe that dates back at least to ancient Greece.

A growing body of evidence shows, however, that we have grossly underestimated both the scope and the scale of animal intelligence. Can an octopus use tools? Do chimpanzees have a sense of fairness? Can birds guess what others know? Do rats feel empathy for their friends? Just a few decades ago we would have answered "no" to all such questions. Now we're not so sure. WSJ
