The issue of Chomsky’s linguistics is not hard to resolve: the idea of recursion is excellent, but not enough for a fundamental linguistic theory. And noone has resolved the actual format of language in terms of neuroscience, nor produced any real insight into language evolution. We don’t even know at what point language really emerged, as per for example homo erectus.
I will bet a buffalo nickel that my World History and the Eonic Effect contains one of the keys to language evolution enigmas, or at least comes close. Study the macro effect on the Axial Age period of the Greek Archaic: we see a late phase of ‘linguistic evolution’, i.e. at the level of song, dance, poetics, and from this period a whole new literature arises. You never even see the processes that do this.
