"Elephant memory and intelligence for thousands of years and scientists have carefully catalogued astounding examples of elephant cleverness in the wild for many decades. In the past 10 years, however, researchers have realized that elephants are even smarter than they thought. As few as eight years ago there were almost no carefully controlled experiments showing that elephants could match chimpanzees and other brainiacs of the animal kingdom in tool use, self-awareness and tests of problem-solving. Because of recent experiments designed with the elephant’s perspective in mind, scientists now have solid evidence that elephants are just as brilliant as they are big: They are adept tool users and cooperative problem solvers; they are highly empathic, comforting one another when upset; and they probably do have a sense of self.”
