When an animal helps another animal, it usually gets something valuable in return. For a long time, many scientists thought that only people could act generously just because it feels good.

However, a new study in Germany suggests that chimpanzees (黑猩猩)also do good things for no real reason. And so do children who are as young as 18 months of age. Maybe it is because humans and chimpanzees share an ancestor(祖先) about 6 million years ago.

People and chimpanzees appear to develop such features(特征) without any other training, says Warneken, a scientist in Germany. Warneken and his partners worked on adult chimpanzees that live on an island in the African country of Uganda. They also worked with 18-month-old children in Germany. The researchers performed three experiments on the adult chimpanzees and two experiments on the kids. In the first animal experiment，a person tried to reach his arm into a cage to get a stick，but he couldn’t reach it. A chimpanzee was in the cage，and it could reach the stick if it wanted to.

Thirty-six chimpanzees took part in this experiment one by one, and no chimpanzee saw what the other chimpanzees had done. Even though the animals hadn’t met the person before, they usually took the stick and gave it to the person. What’s more, they did this whether or not the person offered them bananas as a reward. In a similar experiment, 36 children acted in a similar way. They helped the person reach the stick, whether or not they were offered toys for their help.

Researchers did other experiments on chimpanzees and babies. No rewards were offered in either experiment. And still, both the chimpanzees and children went out of their way to help. Still, the new study is different from earlier findings. Researchers have found that chimpanzees don’t give rewards of food to other chimpanzees, even if it costs them nothing to be generous.

Many animals recognize their food because they see it. So do humans. When you see an apple or a piece of chocolate you know that these are things you can eat. You can also use other senses when you choose your food. You may like it because it smells good or because it tastes good. You may dislike some types of food because they do not look, smell or taste very nice. Different animals use different senses to find and choose their food. A few animals depend on only one of their senses, while most animals use more than one sense. 
Although there are many different types of food, some animals spend their lives eating only one type. The giant panda eats only one particular type of bamboo. Other animals eat only one type of food even when given the choice. A kind of white butterfly will stay on the leaves of a cabbage, even though there are plenty of other vegetables in the garden. However, most animals have a more varied diet. The bear eats fruits and fish. The fox eats small animals, birds and fruits. The diet of these animals will be different depending on the season. 
Humans have a very varied diet. We often eat food because we like it and not because it is good for us. In countries such as France and Britain, people eat foods with too much sugar. This makes them overweight, which is bad for their health. Eating too much red meat and animal products, such as butter, can also be bad for the health. Choosing the right food, therefore, has become an area of study in modern life.
