Morphological fundamentals

Abstract

This chapter is devoted to a detailed reconstruction of the morphological fundamentals of language with particular focus on the functioning of the structures considered in CBM simple externalization interfaces. The Darwinian perspective is more suitable to rebuild the current morphology of human language as a gradual shaping of natural selection in the musculoskeletal and neurocerebral apparatus. Continuity with other primates is discussed here in connection with the evolution of the supralaryngeal vocal tract and the auditory cortex. The differences are measured through selective changes in these organs, always within the framework of the general constraints of form and development (Evo-Devo).
