TL;DR: In this article, the authors integrate life history, evolutionary psychology, and human biology approaches to address the question of how and why our minds generate different levels of attraction to others, and identify different domains of social value for which attractiveness assessment evolved, and review evidence for some of the hypothesized attractiveness-assessment adaptations in those domains.

TL;DR: Data on 678 injuries and illnesses suffered by 40 Shiwiar forager-horticulturalists is presented, suggesting that the Shiwian population structure and lifeway are dependent on infrequent extended provisioning to temporarily disabled individuals, and that provisioning of aid during healthcare crises effectively lowers mortality in this small-scale society.

TL;DR: Data on cross-cultural perceptions of facial masculinity and femininity are presented and it is found that in less developed environments, typical “Western” perceptions are attenuated or even reversed, suggesting that Western perceptions may be relatively novel.

TL;DR: The hypotheses that social exchange algorithms are species-typical and that their evolutionarily stable strategy (ESS)-relevant subroutines are developmentally buffered against cultural variation are supported.
