Based on a sample of 338 Chinese parents and their only children, paternal resemblance belief was found to attenuate the association between paternal harsh parenting and child characteristics, such as emotion dysregulation and aggression, and to strengthen the association between harsh parenting and such paternal characteristics as depressive affect and marital dissatisfaction. These findings support the evolutionary view that, as an adaptation to calm paternity doubt, paternal resemblance belief leads to improved paternal investment.
Mating is close to the engine of the evolutionary process—differential reproductive success. As descendants of reproductively successful ancestors, modern humans have inherited the mating strategies that led to our ancestor’s success. These strategies include long-term committed mating (e.g., marriage), short-term mating (e.g., a brief sexual encounter), extra-pair mating (e.g., infidelity), mate poaching (luring another person’s mate), and mate guarding (effort devoted to keeping a mate). Since men and women historically confronted different adaptive problems in the mating domain, the sexes differ profoundly in evolved psychology of mating solutions. These psychological sex differences include possessing distinct mate preferences, dissimilar desires for short-term mating, and distinct triggers that evoke sexual jealousy. This article reviews empirical evidence supporting evolution-based hypotheses about these mating strategies. The study of human mating is one of the true “success stories” of evolutionary psychology
