[To eat or to speak]

Human oro-pharyngeal feeding is old as mammals's (150 millions years). This fonction is performed and coordinated by the central and peripheric nervous system. Thus, eating and speaking use the same anatomic ducts and ways. To that purpose, the Broca praxic language area is close to the praxic area of the motor mastication and swallowing control in brain cortex. This area, a new innovation of human evolution, is connected directly with the old motor ways of preexisting oral feeding. The brain connectome and Foxp2 gene have contributed with efficiency to this linking when the language came.
