Chomsky and people who study in the generative tradition have a lot to say about language as a biological organ (which obviously evolved from the language organs Chimps possess). In fact, Chimps have very similar systems to us. They can perceive voiced onset time (VOT) just as we do and they can reason about semantic issues. They can also utter and understand sound-meaning pairs however, they have nothing like our syntax for making novel and complex utterances out of the simple ones.
