The Evolution of Language: A Neurobiological Perspective
S. Karthick, and S. Barwa. International Journal of Research in Medical and Basic Sciences3 (9):
Language is the unique power bestowed upon human being to represent and share unbounded thoughts. Its evolution is one of the most interesting and significant evolutionary events which has occurred in the last 5–10 million years, and indeed during the entire history of life on earth. Language has a long evolutionary history and is closely related to the brain, but what makes the human brain uniquely adapted to language is unclear. The regions of the brain that are involved in language in humans have similar analogs in apes and monkeys, and yet they do not use language. Given its central role in human behavior, and in human culture, it is unsurprising that the origin of language has been a topic of myth and speculation since before the beginning of history. It is assumed to be arising from three distinct but interacting adaptive systems: biological evolution, cultural transmission, and individual learning. A biological understanding of language would surely entail a full understanding of how brains generate, represent and manipulate concepts and such a broad understanding of cognitive neuroscience remains a distant hope today to understand the neurobiology of language & language development some pessimistically suggest it is forever beyond the reach of the human mind.
