Question

　　Of all the animals in the animal kingdom, which one (aside from man) is the cleverest?

　　There're several ways of measuring the intelligence (智能) of animals. In one test a scientist sets three identical (一样的) cans on a table. While the animals watches, he puts food under one of the cans. Then he leads the animal away. Some time later, he brings it back to see if it remembers which can has the food. No smelling is allowed; the animal must go directly to the correct can or it falls.

　　This is called a delayed-response test. The idea is to find out how long an animal's memory can keep information. The scientists would try showing the cans to the animal one hour later, or two hours later, or even a full day later. They discovered that chimpanzees (黑猩猩) and elephants have the best memory, and are able to remember the correct can for at least twenty hours. No other animal is close. Dogs came next, but they only remembered for nine hours.

　　To settle the matter, the scientists designed a huge maze (迷宫) and ran the chimps and elephants through it. The maze was very difficult, with many blind paths and dead ends. It took the chimps ten minutes to find their way out. The elephant needed a half hour. Even allowing for the elephants' lower rate of speed, the test shows that chimpanzees are the cleverest animals. From this and other tests, the scientists drew the following conclusion: an animal's intelligence depends on the size of its brain in proportion (比例) to the size of its body. The elephant's brain weighs ten pounds. But this is only 1/600 of its 6000 pound body. A chimp's brain weighs about one pound, or 1/20 of its total body weight. So in proportion to its body size, the chimp has four times as much brain as the elephant—more brain for less body. The chimp is the champ!
