It is often said that "necessity is the mother of all inventions". Then, the pertinent question remains “What necessitated the development of Language?” or the question that is even more baffling is “Why did only humans do so and not any other creature?”
In this regard, it must be mentioned that we, humans, do not have any typical so called ‘organs of speech’ (other than the Larynx), rather, we use organs of respiratory system and digestive system to articulate different sounds. So, it is not at all hard to imagine that when humans were in the early stages of their evolution they did not have any special organ for language. Thus, they were very much like the other animals around. Then, what on earth propelled the development of an oral communication system which is now called a LANGUAGE?
These questions had been baffling me for years until I got acquainted with Anthropology. It was now that I could relate the evolution of Language as a part of Hominid evolution. The social and geological factors that played their part in the later part of the evolution of the homosapien sapiens , must have had some impact on the evolution of Language as well.
For example, I can now try to answer one of my questions, “Why did we develop so many different languages rather than one universal language?” The answer may be that there was a stage in the evolution of human society and civilization when the humans began settling down. This act obviously meant rivalry and clashes between different clans or groups for the prime land. It was this competition that necessitated the development of different codes of communication. This indigenous code would have been their mark of identity that could not be faked by the outsiders; this practice might have given birth to names. I think, going by this hypothesis, we can now justify the existence of so many different languages rather than one universal language.
Similarly, the geographical factors also played their part. While some linguistic groups constantly fought and mingled, some remained isolated even till modern ages untill the development of modern means of communication.
In addition, I believe that the Darwin’s concept of “Survival of the fittest” is applicable in case of Languages too. Just as the weak genes perished so did the weak languages- the languages that did not have powerful speech community behind them. Here we can raise the question "Why did Sanskrit - the language of the elites and the kings- perish?" The answer may be that this marvellous language, unfortunately, remained restricted to the elites and royals only. Consequently, it lacked the mass behind it to stand the test of time.
In short, all I want to say is that we must start exploring the origin, evolution and development of Language parallel to the evolution of the humans and their society. The story of Language must be as complex and interesting as the History of humans themselves. Let us explore it.
Please enlighten me on this subject if anyone knows anything more.
Thanks
