Language Evolution - Absolutely New Way of Thinking

IS IT ONLY LANGUAGE EVOLUTION THAT HAS NOT BEEN EXPLAINED?  Reading the abundant literature treating the evolution of language with a preliminary consent of failure to build up a theory that would come close to the stream of real events that made language live, is frustrating. Yet, is this frustration justified? Do we already have a well developed theories of other abilities of human beings? Of walking, for instance? of the many ways of using our hands? of sexual courting?

Such answers, surely much richer in details, usually describing the structures of legs and pelvics (see for example this paper evolution of human walking ). What we get in such descriptions equals, when talking of speech, to description of the changes of the organs of the vocal tract, What we actually look for is the de...

Surely the headline question has many aspects, and a short post can't take the mission of answering it correctly.

Rather it is regarded as a collective name of  fitness and capability of producing meaningful patterns by voice, writing or signing. The common perception of language shared by most people and ...
