O modelo de tomasello sobre a evolu？？o cognitivo-linguística humana

the present paper aimed to present tomasello's approach about human-cognition evolution and a derived theory of acquisition and development of linguistic-symbolic competences. tomasello proposes that symbolic acquisition and development depend on an exclusively human cultural cognition derived, however, from primate biological adaptations. these approaches represent some alternatives to traditional treatments for human cognitive and linguistic-symbolic development, considering that they: (1) highlight biological and cultural features as determinants of human cognition; (2) consider human activities as essentially symbolic; (3) offer a new conception of language.
