Nobody knows why but humans talk. Some say that we do it thanks to the birds that were the first sounds that Homo Sapiens could imitate. But like the birds in the recesses of our species, nature propitiated many sounds to imitate like the noise of the water, the storms or perhaps the breezes in the mountains. The howl or meow of the animals and even the glute of the fish can not be ruled out.
But students of communication believe that talking is a miracle of our condition of human nature; and is mainly associated with sounds that birds emit. Hence, each region of the planet has disseminated hundreds and thousands of languages as a result of the sounds produced by the birds of those places. This theoretical explanation of communication, sometimes has its cobwebs because with the migration of birds many of our languages should have some resemblance, rather than variants in its complex development over time is known as phonological tree.
In recent decades some scientists managed to build a language that claims to be universal that can become a second mother tongue and that does not sacrifice the native language over another that wants to position itself as Universal as English. Although it is a fascinating topic I will not debate about this language and its nuances I will leave your link for those who want to know more about it or perhaps learn it.

A nightingale, a liberal (Venezuelan bird in danger of extinction) or who knows which one; that is somewhere in this world. Every day a new stream of language is formed. As social or ethnic circumstances. The language or language has proposed an irreverent phrase that challenges Esperanto and that has been marketed "here is spoken ..."
