I think that everybody is interested in the question of how humans acquire language and what language is because it is one thing that is special to the human species and is universal among humans. A lot of different explanations were given to how children acquire language and how grammar gradually emerges. I have investigated different ideas concerning language acquisition, especially the one proposed by Noam Chomsky which is called Universal Grammar. I tried to find evidence in the literature for the theory and I also found articles that provide points of criticism in connection with the hypothesis.
