Language and social learning appear to be closely related biological phenomena. The cortical areas of the left hemisphere that lies around the fissure of Sylvius are related to the phenomenon of social learning both in man and apes. This cortical areas are the same devoted to the faculty of language in modern humans. Furthermore social learning exhibit a functional coupling of both semantic and syntactic aspects that pre-date the origin of language itself. The extensive and fast-growing of the left perisylvian cortical areas since early Homo more than 2 milions years ago, can be properly linked to the individual advantage to possess a much more efficient and accurate non-verbal system for an early learning by imitation of the know-how and technical skills to have access to food resources, including nutrients essential to support the development of the brain not otherwise available. From a Darwinian point of view, the increased capabilities of social learning in Plio-Pleistocene hominins provides the key adaptations for the further evolution of language.
