Apologies if I'm stepping on a joke, but just in case: Nativism is about cognitive capacities, not sensorimotor ones. All apes could easily communicate just as well as Helen Keller, yet none of them have ever asked a question, much less written a book!

No joke. Same sensorimotor neurons in the human speech apparatus have cognitive analogues, developed together over vast expanses of history.
