SUMMARY:Mike Gurven - Implications of personality variation in a small-scale society
DESCRIPTION:Mike Gurven: UCSBPersonality traits (i.e. behavioral syndrome or disposition) have now been documented in a large number of species\, and account for substantial behavioral variation among individuals. How heritable variation in personality is generated and maintained in populations\, however\, remains a puzzle to evolutionary biologists. Despite the industry of personality research in humans\, relatively little tests evolutionary hypotheses and none in small-scale societies experiencing high fertility and mortality. I present personality data from Tsimane forager-horticulturalists and test whether the Big Five dispositional traits are related to fertility\, health and other fitness-related outcomes. I also argue that a focus on personality differences can shed insight on small group social dynamics. Results are discussed in light of alternative notions of state-dependence\, balancing and fluctuating selection.

SUMMARY:Bernard Chapais - Human society: What is it and how did it evolve?
DESCRIPTION:Bernard Chapais: University of MontrealThe social structure of any species is an emergent biological phenomenon and as such it has an evolutionary history. The human social structure is no exception to that rule but it has an important peculiarity: it is hidden from view by its numerous cultural expressions. To circumvent the problem and characterize the deep structure of human society one must carry out a comparative analysis of human and nonhuman primate societies and employ evolutionarily significant categories. Using that approach I define human societies as nested associations of multifamily groups\, a structure made up of a specific set of features\, notably\, strong ties between groups stemming from the linkage of kinship bonds and pair bonds\, a uniquely human trait. I also argue that primatology makes it possible to define a five-step model of the maximally parsimonious evolutionary sequence that led to human social structure. Finally I show how the present phylogenetic perspective informs functional analyses of human behavior by pointing to the ‘adaptive suite pitfall’and the importance of phylogenetic constraints.

SUMMARY:Laura Fortunato - The evolution of the human family
DESCRIPTION:Laura Fortunato: SFICompared to other species\, humans show a remarkable degree of variation in family organization. This talk presents recent advances in the application of evolutionary thinking to the study of the human family\, focusing on the evolution of monogamous marriage. First\, I present the results of a game-theoretic model investigating the co-evolution of marriage and wealth inheritance strategies. The analysis shows that where resources are transferred across generations\, monogamous marriage may be advantageous because it “concentrates” wealth in a limited number of heirs. It may also be advantageous because a female may grant her husband higher probability of paternity if he marries monogamously\, leading to exclusive investment of his resources in her offspring. This may explain why monogamous marriage prevailed across societies of Europe and Asia practicing intensive agriculture\, and why it first emerged in these regions: here land was limited and the partitioning of estates depleted their value. Consistently\, cultural norms promoting high paternity\, such as ideologies of virginity and sexual fidelity\, were common in these societies. Second\, I present the results of two case studies testing specific predictions of the theoretical model. One case study focuses on evaluating the prediction of an “early” origin of monogamous marriage\, linked to the development of intensive modes of production such as plough agriculture. In agreement with this prediction\, phylogenetic comparative analysis of marriage strategies across Indo-European-speaking societies reconstructs monogamous marriage as the ancestral state. The other case study focuses on the predicted association between monogamous marriage and norms stipulating the transfer of wealth to a man’s wife’s offspring\, as opposed to alternative inheritance strategies. This prediction is supported by analysis of variation in marriage and inheritance strategies across a world-wide sample of societies\, while controlling for the confounding effects of Christianization. Finally\, I discuss implications of these findings for our understanding of the evolution of human family systems. \n*** Please note that due to technical difficulties\, the audio quality of the videos has been impaired.

SUMMARY:Martin Muller - Behavioral Ecology and Socioendocrinology of Reproduction in Male Chimpanzees
DESCRIPTION:Martin Muller: University of New MexicoThe Kanyawara chimpanzees of Kibale National Park have been studied for 25 years\, during which researchers have acquired a unique\, 14-year longitudinal sample of hormonal data. Dr. Muller will draw on these data to discuss the role that testosterone plays in supporting male mating effort\, the energetic costs of male-male competition\, and the impacts of such competition on females.

SUMMARY:Dawn Neill -  Roti or Ramen:  The Behavioral Ecology of Food Choice among Rural and Urban Indo-Fijians
DESCRIPTION:Dawn Neill: Cal Poly SLOUrbanization is proceeding rapidly in many developing countries as part of a larger process of development and involves the shift of rural residents to urban cities.  The shift from a rural to urban ecology entails changes in patterns of food production and/or purchase\, preparation\, and consumption.  Existing research has consistently demonstrated an association between urbanization and dietary changes linked to increasing rates of overweight and obesity.  Rural-urban variation in food cost and availability modifies the individual-level costs and benefits associated with dietary choices.  It is suggested that the traditional rural dietary pattern is undergoing modification as urbanization occurs and individual food choice tradeoffs result.  Empirically-derived diet clusters are created from 24-hour dietary recalls from 306 urban and rural living Indo-Fijian children.  Results suggest the existence of a rural-traditional vegetable-based pattern and an urban-modified pattern.  Using an embodied capital framework\, mother’s education is shown to be the strongest predictor of diet\, along with number of offspring and parents’ childhood ecology; urban ecology does not significantly predict diet.  Mother’s embodied capital is also shown to be significantly associated with higher child BMIs\, regardless of diet.
