When formed the languages?
Today, we are assuming that our species was not created in a moment, but evolved from earlier forms, has more than us today the apes were similar. Although there are historical issues of our translation agency in the way, in particular, a question arises in connection with the origin of languages: at what point the man became a man? In other words, when the earlier forms we were so similar that we would describe as being of our species?
A common answer to this is that man to man was just then, as the language developed, and that would fit exactly to the traditional narrative. For us it is natural to consider those creatures as people who use a human language.
This gives us but still no precise answer to the question of when the first humans appeared on the scene. We do not know when the first sentence was spoken. Well, many smart people have tried to define since antiquity, when and how this happened, but the results are not exactly impressive.
With absolute certainty we know that human languages have existed since at least 5000 years, for about the same age are the first surviving written evidence of language. The first detained in writings languages, Sumerian and Egyptian, differ in their general characteristics are not the least of languages spoken today. It seems certain therefore that there has been very much more languages, the modern languages were similar. (As a translation agency we are deeply concerned with this subject and researched.)
How long, however, is unclear. Since there is no direct evidence, all assumptions are purely speculative. Mostly they were looking for a coherent response using two types of evidence. The one source of information on the general cultural development of prehistoric man. These are based on archaeological finds and many artifacts. The other source of knowledge about the anatomical development of man. Here, too, the Archaeological material in the form of bone-au, different periods.
