TOKYO - Charles Darwin, originator of the theory of evolution in the world's most famous reveals that humans came from a family of primates (apes). Human evolution is said to be related primates are "missing", can not be proved correctness of the theory. In fact, popular Darwin's theory could be controversial conversation.
Reported ScienceBlog, (22/02/2013), Charles Darwin wrote in The Descent of Man (1871), reveals that the votes cast by birds offer in several nearest analogy of language.
Human language, according to Darwin, has its origins from the sounds of animals that live in the vicinity. In addition, the sound of birds chirping also bears the words expressive of complex emotions.
Now, researchers from the Massachusetts Institute of Technology (MIT) and the University of Tokyo said that Darwin, was in the correct way. Further research revealed that human language is a continuation of the two forms of communication.
This form of communication found in the animal kingdom. First, singing birds and the second complex, information pertaining to the diversity of expression seen in other animals.
"It's a combination of accidental triggering of human language," said Shigeru Miyagawa, 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 the research framework Miyagawa, researchers revealed that the song of a bird very much resembles a layer of expression of the sentence (in) human.
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 Computational linguistics professor, Robert Berwick at MIT.
Furthermore, he said, researchers saw this repeatedly in evolution. "The old structures can change just a little bit and get a radically new functionality," he concluded.
