Do animals have a culture? What do we mean by "culture"? Recently social scientists have begun to ask if culture is found just in humans, or if some animals have a culture too.  When we speak of culture, we mean a way of life that a group of people have in common. Culture is the forms of behavior (行为)hat help people to live together. It is also the forms of behavior that make one group of people different from another group.
Human beings use tools, cooperate with one another, and communicate with language.  But these aspects(方面) of human behavior, or "culture", can also be found in the lives of certain animals, Animals can make tools, for example. We used to think that the ability to use tools was the dividing line between human beings and other animals.  Lately, however, we have found that this is not the case. Chimpanzees(黑猩猩) can not only use tools but actually make tools themselves. Animals can also share knowledge with each other and use their own language to communicate. So it may be important for us to know that the line dividing us from animals is not as clear as we used to think.
