Evolved but Not Fixed: A Life History Account of Gender Roles and Gender Inequality

Abstract

The rift between evolutionary psychology and the biosocial model of gender relations impedes a fuller understanding of gender roles and gender inequality. In a novel evolutionary account that complements both existing theories, we highlight life history strategies as intermediate mechanism linking distal environmental forces to variations in gender relations. Specifically, traditional versus modernized gender roles are seen as shaped by present-oriented versus future-oriented reproductive strategies, which are sensitive to uncontrollable morbidity-mortality risks. Gender inequality stems from a combination of present-oriented reproductive strategies adapted to high-risk environments and dominance hierarchies resulting from societal competition (i.e., the probability of obtaining resources desired by others through personal efforts). By contrast, gender egalitarian values develop as people increasingly enact future-oriented reproductive strategies in a competitive but orderly and controllable environment, which is conducive to prestige hierarchies. The current account provides novel interpretations of phenomena ranging from sex differences in mate preference, sociosexuality, and sexism to cross-cultural variability in marital systems and cultural practices. All of these serve to support the view that gender relations are evolved, changeable, and influenced by the interaction between ecological and social environments in ways predicted by the life history mechanism.

Of Time Gals and Mega Men: Empirical Findings on Gender Differences in Digital Game Genre Preferences and the Accuracy of Respective Gender Stereotypes

“…Another explanation takes an evolutionary perspective (e.g., Lueptow et al, 1995 ; Zhu and Chang, 2019 ; see also Mealey, 2000 ). It is not necessarily at odds with, and even in accordance with the other explanations, but adds the ultimate ‘why’ question (cf.…”

Life History Orientation Predicts COVID-19 Precautions and Projected Behaviors

“…In environments that are more predictable, slow strategists can orient toward long term planning and more affiliative social behaviors ( Ellis et al, 2009 ; Figueredo et al, 2018 ). One can afford to invest in a social orientation that includes coexistence and cooperation with others to maximize resource acquisition through collaboration ( Chen and Chang, 2016 ; Zhu et al, 2018 , Zhu and Chang, 2019 ).…”

Meta-Analysis of Direct and Indirect Effects of Father Absence on Menarcheal Timing

“…Paternal care is evidenced in humans by the father assuming the role of a helper at the nest. Paternal and biparental care of the offspring represents one of many interrelated slow LH strategies, including pair bonding, monogamy, and gender equality development (Zhu and Chang, 2019 ). In terms of both direct parental care and indirect parental investment in the form of provisioning, a father is essential in supporting slow LH strategies and development in human children (Geary, 2000 ).…”
