Oct 28, 2014 · Human cooperation is highly unusual. We live in large groups composed mostly of non-relatives. Evolutionists have proposed a number of explanations for this pattern, including cultural group selection and extensions of more general processes such as reciprocity, kin selection, and multi-level selection acting on genes.

Jun 1, 2006 · Elsewhere (Henrich & Henrich, in press), we have discussed how cultural evolution can facilitate niceness, and thus promote sustained cooperation, by (1) turning an n-person cooperation dilemma into a dyadic situation, (2) guaranteeing that individuals will stick around for the long run, and (3) using kinship to transcend the life of an individual and extend the time horizon into the future ...

We review the major evolutionary mechanisms that have been proposed to explain human cooperation, including kinship, reciprocity, reputation, signaling, and punishment; we discuss key culture–gene coevolutionary hypotheses, such as those surrounding self-domestication and norm psychology; and we consider the role of religions and marriage systems.
Jun 27, 2007 · Abstract. Cooperation among humans is one of the keys to our great evolutionary success. Natalie and Joseph Henrich examine this phenomena with a unique fusion of theoretical work on the evolution of cooperation, ethnographic descriptions of social behavior, and a range of other experimental results. Their experimental and ethnographic data ...
a coevolution of kinship structures, cooper-ation patterns, institutions, and cultural traits. On the one hand, the broad cooperation and trust patterns of loose kinship societies are supported by large-scale institutions and “internal police officers” that broadly sanction wrongdo.
Jun 3, 2019 · Natural selection generally favors the evolution of behaviors that enhance the fitness of individuals. Cooperative behavior, which increases the fitness of a recipient at the expense of the donor, contradicts this logic. William D. Hamilton helped to solve the puzzle when he showed that cooperation can evolve if cooperators direct benefits ...

differs, but the intent—to greet—does not. The particular theory espoused by the Henrichs—dual inheritance theory—can be described as follows: our capacity for coopera tion evolved through the interaction of culture and genes. Genetic evolution endowed humans with the capacity to cooperate, while cultural evolution, which happens much ...
