Why is language unique to humans?

Researchers at the University of Durham explained that human beings are required to create and use signals in a flexible way for their own expressive power of human language. They argue that he can only be enabled by the evolution of certain mental abilities, and explain why the language is human-specific.

Thomas Scott-Phillips et al., Using mathematical models, the evolution of signals that combines two or more signals is crucial for the ability of human language to express, usually unless there is a specific species present It is difficult to show. Certain psychological mechanisms, otherwise it will be human, there may not be other species, these are, there are these, why only human beings can explain the language

In a compound communication system, some signals consist of combinations of other signals. Such systems are more efficient than comparable unbound systems, but they are inherently rare. Reason why this is the case Previous research was not fully explained. The new model shows that interdependence of signals and responses imposes severe restrictions on past possible paths of combined signals and that other forms other than the simplest form of coupled communication are extremely unlikely I will.

Scientists believe that these restrictions can only be avoided if individuals have enough social cognitive abilities to clearly communicate. Humans may not have other species, but have this ability. This may explain why a large complex language is an extreme exception to the general tendency of nature.

Because some people define "language" as "human language", this is roughly circular discussion, "language" can not be human-specific. Whatever the uniqueness of the human language, it makes it unique and unique. We all agree that the human language is different in some way from the animal. Maybe we can concentrate on how to learn languages. That's why the majority of the argument that 'human language is unique' comes from this. The main argument is that the human language is too complicated to learn from input (there are too many possibilities for what we hear, we are unknown spiritual "grammar" You have to guess). Was born. Human, part of our DNA. Of course, this is not just a word, but because of the basic ability you can "learn" from a specific language such as English (in fact it is a better word to "get").

In the human world, language and communication are unique due to their rationality. Language validity distinguishes human language from animal whisper or signal. In the animal kingdom, words are expressive. Human words appear on the logo on one hand, but they are not strict. Human language is variable in the sense that it has different languages, and in the same language the same expression may specify different or different expressions at the same time.
