Chimpanzees use a system of different sounds to communicate with each other. These sounds have (VARIERY) various (MEAN) meanings and chimps use them as a means of (COMMUNICATE) communication .This is one (SIMILAR) similarity between chimps, whales and dolphins. There has been a great deal of (SCIENCE) scientific research into this (RECENT) recently .However, this reseacher has not produced (PROVE) proof that these animals really have a language. A (COLLECT) collection of sounds is not the same thing as a language, which has some kind of (GRAMMAR) grammatical structures. Most scientists are in (AGREE) agreement about this.
