Ultimate and proximate explanations of men’s physical intimate partner violence (IPV) against women have been proposed. An ultimate explanation posits that IPV is used to achieve a selfish fitness-relevant outcome, and predicts that IPV is associated with greater marital fertility. Proximate IPV explanations contain either complementary strategic components (for example, men’s desire for partner control), non-strategic components (for example, men’s self-regulatory failure), or both strategic and non-strategic components involving social learning. Consistent with an expectation from an ultimate IPV explanation, we find that IPV predicts greater marital fertility among Tsimané forager-horticulturalists of Bolivia (n = 133 marriages, 105 women). This …
"Till Death Us Do Part: The Evolution Of Monogamy, Kirsten Glaeser
"Till Death Us Do Part: The Evolution Of Monogamy, Kirsten Glaeser
Oglethorpe Journal of Undergraduate Research
With statistics indicating that one out of every two marriages in the United States ends in a divorce, the validity of monogamous marriages has come under fire. Are humans truly capable of maintaining monogamous marriages or are they constraining their sexuality by doing so? The research entails two different perspectives while analyzing human monogamy; monogamy as a mating pattern and monogamy as a marriage pattern. The reason being that monogamy is solely not an evolved phenomenon but also a socialized one throughout most cultures. While analyzing monogamy as a mating pattern, several occurrences throughout our evolution allowed humans the ability …

What causes marital conflict, and which marital conflicts are more likely to result in men’s violence against their wives? It has long been argued that men’s jealousy over women’s infidelity is the strongest impetus to men’s lethal and non-lethal violence against female partners. Less is known about the extent to which women’s jealousy over men’s infidelity precipitates men’s violence against female partners. Husbands are more likely than wives to commit infidelity, and men and women report a similar frequency and intensity of jealous emotions during recalls of potential infidelity. If men are likely to use time and resources for pursuit …

Children may be viewed as public goods whereby both parents receive equal genetic benefits yet one parent often invests more heavily than the other.We introduce a microeconomic framework for understanding household investment decisions to address questions concerning conflicts of interest over types and amount of work effort among married men and women. Although gains and costs of marriage may not be spread equally among marriage partners, marriage is still a favorable, efficient outcome under a wide range of conditions. This bioeconomic framework subsumes both cooperative and conflictive views on the sexual division of labor. We test hypotheses concerning marriage markets, …
Costs And Benefits Of Monogamy And Polygyny For Yanomamö Women, Raymond B. Hames
Costs And Benefits Of Monogamy And Polygyny For Yanomamö Women, Raymond B. Hames
Department of Anthropology: Faculty Publications
In this paper I analyze some of the economic costs and benefits of monogamy and polygyny for Yanomamö women. The evolutionary ecological model of resource defense polygyny predicts that when female choice is operative females will choose those males who control resources that will maximize a female’s reproductive success. A female will choose a polygynous strategy (i.e., become a co-wife) if a currently married male has more resources to offer than other unmarried males or monogamous males. This model has been successfully used to predict polygynous mating in tribal societies where males are stratified in terms of their ownership or …
