Man finds living together with his own species(物种) difficult enough and living together with other species almost impossible. Our usual solution is to kill off anything that get in our way. Even on those rare occasions when we do enter into a relationship with another species, it is heavily biased(带有倾向) in our favor. The other species benefits only when it suits our own interests. Our attempts to communicate with another species are concerned mainly with giving orders in our own language and having them obeyed. Probably our best attempt has been the whistle language that is used in the shepherd-sheepdog relationship. This is a system that is natural to neither species, but one that both can understand. Its only fault lies in fact that the bias is still there--the dog cannot whistle for the man. But now comes news of a piece of research that promises, for the first time, to open up two-way communication between man and another species. At the University of Nevada in thewestern United States, animated(活跃的)conversations are being held with a young female chimpanzee (黑猩猩)called Washoe. Allen and Beatrice Gardener have succeeded in doing this because they have used an entirely new approach, an approach based on the natural abilities of the chimpanzee. Past attempts to communicate with chimpanzees have failed because the researchers tried to make their animals use a vocal language.
