Noam Chomsky also proposed the theory that a kind of universal grammar, a grammar that underlies all human languages, is hard-wired in the human brain.  Thus all human languages are fundamentally the same, with only superficial differences.

===Criticism===

Both the theory of universal grammar as well as genitive grammar have been criticized over time.  A primary argument is that the majority of Chomsky's studies are based in English, and do not represent "human language" as a whole.  Linguist Geoffrey Sampson suggests that the core of his arguments  are not scientifically falsifiable, and therefore hold no more weight than mere opinion or conjecture.  Sampson follows that Chomsky does not seem to be able to make predictions of what is possible in a language.
