Resumen de Saltos funcionales en la evolución del lenguaje: de un protolenguaje léxico-simbólico distribuido al habla del humano anatómicamente moderno
Functional steps in language evolution: from a distributed lexico-symbolic protolanguage to the speech of anatomically modern humanThis paper presents the Extended TESE theory, which proposes the evolution of language through three functional steps: distributed symbolic-lexical protolanguage; human speech, and recursion. This theory is based on an evolutionary framework that includes biological emergencies (exaptation, epigenesis, symbiogenesis, deep homology) as an everyday process that complements the role of natural selection. It is also based on a conception of the mind consisting of weak modules or distributed functional neural systems. Finally, it sympathizes with a linguistic description similar to what non-transformational generative grammars do. This paper discusses the first two steps, stressing the symbiotic relationship between protolanguage and symbolic processes, as well as anatomical and neural specific peculiarities of speech. Extended TESE fits into an externalist structuralism.
