Scientists in Australia have found that bees seem to understand the idea of zero. This is surprising since bees have very small brains. Studies have shown that only humans and a few animals such as monkeys and some birds understand zero. And humans usually don't understand it until they're around four years old. But bees are smarter than they look. Scientists already knew that bees could count up to four. They also knew that bees could "talk to" each other. By dancing in some ways, bees could tell other bees how far away the food was and in what direction.
Scientists at RMIT University in Australia came up with a smart way to test whether bees understood the concept(概念) of zero. They prepared some cards with different numbers of shapes on them. First, they had to train the bees by giving them sugar water to make them choose the cards with fewer shapes on them. They put something sour(酸的) under the cards with more shapes on them. Soon the bees knew there was sugar water under the cards with fewer shapes.
After about 40 tests, the bees learned to choose the cards with different numbers of shapes. Then came the interesting part. The scientists put a card with nothing on it. Even though they had never seen it, the trained bees chose the blank(空白的) card. This showed that they knew that zero or "none" meant less than "some".
Bees' brains are about 86,000 times smaller than the brains of humans. How are they able to do so much with such a small brain? Scientists want to study more bees to find out more. Many are now trying to create machines that can "think" like bees. By learning how the bees' brains work, they may be able to use some of those ideas to teach computers and robots some new tricks.
