Humans are, in the sense that we're working off the checkpoint passed to us from our parents: the bare minimum language centers our brain is evolved to produce regardless. The sequence of checkpoints evolves effectively from scratch, but individual humans adapt the checkpoint for their environment from birth. I like to think of the brain as the general model we've trained with evolution, and the person's experiences as the specialization.
