Yocha News- Charles Darwin, originator of the theory of evolution's most famous in the world reveals that humans came from a family of primates (monkeys). Human evolution is said to be related primates are "missing", can not be proved correctness of the theory. In fact, this popular Darwin's theory had become controversial conversation.
Reported ScienceBlog, Charles Darwin wrote in The Descent of Man (1871), reveals that the votes cast by birds offer in several languages closest analogy.
Human language, according to Darwin, has its origins from the sounds of animals that live in the vicinity. In addition, the sound of chirping birds also bear the words expressive of complex emotions.
Now, researchers from the Massachusetts Institute of Technology (MIT) together with researchers from the University of Tokyo said that Darwin, being in the right way. Further research revealed that human language is a continuation of the two forms of communication.
Form of communication is found in the animal kingdom. First, the birds singing and the second complex, information relating to the expression of the diversity seen in other animals.
"This combination of accidental triggering of human language," said Shigeru Miyagawa, a professor of linguistics at the Department of Linguistics and Philosophy, MIT. This idea builds upon the conclusion Miyagawa.
Conclusions are never revealed in previous studies, in which he explains there are two "layers" in all human languages, which includes a layer of expression organizations related sentences can be changed.
In addition, a layer of "lexical" related to the core content of the sentence. Based on the analysis of animal communication and using research framework Miyagawa, researchers revealed that the song of the bird closely resembles the lining of the sentence expression (language) humans.
At some point, between 50 thousand and 80 thousand years ago, humans may have combined these two types of expressions in the form of a unique language. "When something new evolving, often built from old parts," said Professor Computational linguistics, MIT Robert Berwick.
He further said, the researchers saw this repeatedly in evolution. "The structure can change just a little longer and get a radically new functionality," he concluded.
