SJ: "Animals seem, in short, to be doing precisely the thing that Chomsky said
humans do not do: applying general cognitive skills to collections of words.
The putative language module, with syntax already built in and allowing
infinite flexibility, is lacking - one of the few human skills that really does
seem to be exclusively human. Animals cannot speak like us; it's just that
the clever ones can use other skills to produce a plausible imitation."
So they speak a different dialect that imitates ours. So what? We cannot fly like some other animals can or swim or hold our breaths or.. or..
