The co-evolution of human intersubjectivity, morality, and language

Abstract

This chapter argues that language, which rests on the sharing of linguistic norms, honest information, and moral norms, evolved through a co-evolutionary process with a pivotal role for intersubjectivity. Mainstream evolutionary models, based only on individual-level and gene-level selection, are suggested to be incapable to account for such sharing of care, values and information, thus implying the need to evoke multi-level selection, including (cultural) group selection. Four of the most influential current theories of the evolution of human-scale sociality, those of Dunbar, Deacon, Tomasello, and Hrdy, are compared and evaluated on the basis of their answers to five questions: (1) Why we and not others? (2) How: by what mechanisms? (3) When? (4) In what kind of social settings? (5) What are the implications for ontogeny? The conclusions are that the theories are to a large degree complementary, and that they all assume, explicitly or not, a role for group selection.
