O papel do linguajar na evolução humana: uma abordagem baseada na teoria da deriva natural

Abstract

The notion of languaging provides a new understanding of the intimate relationship between sociality and language. In this paper, I address the evolutionary emergence of language by subscribing to the autopoietic theory of natural drift. I show that this systemic approach to evolution can offer the ideal epistemological background to evaluate the role of languaging throughout hominization. The central idea is that the languaging-based way of living acted as an attractor for the evolutionary process. This claim relies on three interrelated assumptions: 1) behavioral and relational habits may channel the course of genetic and structural change; 2) recursive coordination and specific forms of sociality set the systemic conditions for coexistence-through-languagingto be conserved over generations; 3) the conservation of these systemic conditions gives rise to a spiraling, positive-feedback process that involves body, cognition, and culture.
