For example, if only human beings communicate with each other, language would have been born as early as when human beings really evolved successfully.
If there is a complete writing system and pronunciation standard not only for communication, but also for recording, it is Sumerian, but it became extinct in the second century before the park.
At present, the academic circles are also arguing. To answer this question, it depends on when language-related cognitive abilities evolved.
Due to the lack of original materials, the understanding of the original language is different, and different viewpoints and schools have emerged in the field of linguistics. Here is our understanding of the original text. We are based on the theory of the essence of language. We believe that the original language has the following characteristics:
1. The original language was an audio language from the beginning.
2. The original language is a combination of sound and meaning from the beginning. Features.
3. Primitive language was associated with people's abstract thinking from the beginning.
4. The original language has three elements from the beginning: pronunciation, vocabulary and grammar.
Our definition of language is actually very narrow. What we usually want to know is a language similar to Chinese, which is a very complete language system. Real language should refer to a quick and convenient way to exchange information, and language is just a form.
As long as we study the time when human ancestors expressed their thoughts through crying, it would be nice if they began to migrate from Africa to other regions.
From the animal's point of view, it is very early to express ideas with calls, and it does not need a particularly high degree of evolution. Then, there is a high probability that there will be language communication before migration.
So the address system before human migration was the earliest language.
