/^t/In the second half of our century scientists achieved a breakthrough in researches on animal's behavior. This breakthrough was caused by a great progress in the field of technology. Since then it has been possible to record even those sounds that are inaudible for the human ear. The most important result of using these technological devices is that it occurred to be a great help for the advocates of the evolutionary theory of continuity. They maintain that humans are not the only beings that are able to communicate with each other by means of their language. On the contrary, those who opt for the theory of non-continuity argue that the human race is the only species able to communicate verbally. Personally, I am convinced that the evolutionary theory of continuity, unlike the non-continuity theory, is very cogent, as there exist many arguments in favor of this theory.
