SUMMARY:Olympia Campbell\, Institute for Advanced Studies\, Toulouse. Title: Cousin marriage\, women’s welfare\, and accelerated family formation
DESCRIPTION:Abstract:Cousin marriage\, practised by over 10% of the world’s population\, restructures kinship networks by overlapping blood and affinal ties. Theory makes competing predictions about how this affects women. “Protection” accounts argue that consanguinity aligns spouses’ interests and increases kin oversight\, reducing coercion. “Constraint” accounts emphasise that dense kin involvement can prioritise family cohesion over women’s autonomy\, suppressing help-seeking. Using demographic data from ~40\,000 women across Egypt\, Jordan\, Pakistan\, and Turkey\, I show that cousin-married women report significantly lower levels of both physical intimate partner violence and coercive control than women in non-consanguineous unions. \nIn the second half\, I examine whether cousin marriage accelerates family formation by reducing search and transaction costs. Marrying kin may eliminate protracted spouse searches and simplify negotiations\, lowering age at first marriage. Using demographic data from the same four countries I test whether cousin marriage reduces age at marriage and increases completed fertility. A fertility advantage could offset genetic costs of inbreeding\, potentially explaining the evolutionary persistence of consanguineous marriage. \n\nZoom link: \nhttps://ucla.zoom.us/j/94308730584?pwd=0YGsaJFEdLd5cMsOhTh465nwJubz9o.1 \nMeeting ID: 943 0873 0584\nPasscode: 308291

SUMMARY:Joan Silk\, School of Human Evolution and Social Change\, ASU. Title: New Perspectives on Male Parenting in Primates: Insights from Baboons
DESCRIPTION:Abstract: \nIn virtually all human societies\, men and women form stable pair bonds\, male reproductive skew is low\, children receive considerable care and resources from both of their parents\, and nuclear families are part of a set progressively larger social units that commonly include kin\, affines\, and unrelated members of the same ethnic group. Understanding of the evolution of this suite of traits is problematic because the most recent common ancestor of humans and the genus Pan probably did not share any of these features. However\, a growing body of data from studies of living primates suggest that there may be multiple pathways to the evolution of male paternal care and extended breeding bonds\, and provide a broader foundation for thinking about the evolution of human reproductive strategies. My research group has been exploring the trade-offs between mating and parenting effort for male olive baboons\, a species with relatively high male reproductive skew and a polygynadrous mating system. Our data provide evidence of behavioural trade-offs between mating effort and parenting effort for males\, changes in allocation of mating and parenting effort across the life course\, and the existence of enduring reproductive bonds. I will describe these data and their implications for understanding the evolution of the unusual set of traits that characterize our own species. \nhttps://ucla.zoom.us/j/94308730584?pwd=0YGsaJFEdLd5cMsOhTh465nwJubz9o.1 \nMeeting ID: 943 0873 0584\nPasscode: 308291
