Elephants Use Their Trunks to Ace Intelligence Tests

Say it ain't so, Dumbo. Elephants rely on their trunks and not those big ol' ears to find their way to food and likely to solve other puzzles, report scientists. (See: "Elephants at Risk.")

Elephants are renowned for their acute senses of hearing and smell, both of which play central roles in their everyday life. But until now, it was not known how important these senses were for basic, everyday tasks. (See: "Elephant Photo Gallery.")
