Just as in other areas of anthropology, the study of language involves investigating what is or isn’t shared across human populations and why these differences or similarities exist. The linguist Noam Chomsky has argued that the human brain contains a limited set of rules for organizing language, so that all languages have a common structural basis. He calls this set of rules: universal grammar.
Universal grammar refers to the genetic component of the language faculty according to which all humans are born with a certain set of structural rules.
Avram Noam Chomsky is regarded to as "the father of modern linguistics" and he performed as philosopher, cognitive scientist, historian, social critic, and political activist as well.
