Of course, researchers can't even agree on what constitutes language among early man.
Of course, researchers can't even agree on what constitutes language among early man. Some consider the proto-language of Homo halibis the first real language. Others say it can be chalked up to Homo erectus, while most believe that what we understand as modern language came from Homo sapiens. We do know that Homo habilis is responsible for bringing tools onto the scene, about 2.3 million years ago. This has led some to believe that the cognitive function of Homo halibis was much more advanced than his predecessor, Australopithecus. According to research, the temporal, parietal and occipital lobes of the brain were physically connected for the first time with Homo halibis. That area of the brain is known now as Wernicke's area, and it has a lot to do with language production. This supports Chomsky and Gold's theory that our brains physically adapted to be able to make tools, and language then arose because of this adaptation.
