Nga Nguyen – Behavioral biology and endocrinology of wild baboons and geladas in East Africa

Nga Nguyen: CSU FullertonMaternal care is the most significant measure of successful adaptation among female mammals. Understanding the predictors of individual differences in offspring care is a major objective of mammalian reproductive biology. In this talk, I will evaluate the impact of maternal and infant characteristics, maternal hormones, and friendships with males on the mother-infant […]

Anne Kandler – Analysing Language Shift: the Example of Scottish Gaelic

Anne Kandler: Santa Fe Institute‘Language shift’ is the process whereby members of a community in which more than one language is spoken abandon their original vernacular language in favour of another. We model the dynamic of language shift as a Lotka-Volterra type competition process in which the numbers of speakers of each language and of […]

Rebecca Sear – How much does family matter? A comparative study of kin influences on fertility

Rebecca Sear: London School of EconomicsThe question of why people have the number of children that they do has still not been fully answered, despite decades of research on this topic. Recently, the hypothesis that humans are cooperative breeders has emerged in evolutionary anthropology, which suggests that the support women receive in raising children from […]

Steve Cole – Social regulation of gene expression: the primate genome’s social program

Steve Cole: UCLA School of MedicineRelationships between genes and social behavior have historically been viewed as a one-way street, with genes in control. Recent analyses have challenged this view by discovering broad alterations in the expression of human and macaque genes as a function of differing socio-environmental conditions. My talk summarizes the developing field of […]

Sharlene E. Santana – Adaptive evolution of facial color patterns in mammals

Sharlene E. Santana: UCLAThe rich morphological diversity of mammal faces has captured the attention of naturalists for over a century. Researchers have long proposed that social behaviors have primarily shaped the intraspecific variation and interspecific diversity in the faces of some visually-oriented groups such as primates. However, mammal faces constitute complex structures where the potentially […]

Mike Gurven – Implications of personality variation in a small-scale society

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 […]

Bernard Chapais – Human society: What is it and how did it evolve?

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 […]

Laura Fortunato – The evolution of the human family

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 […]
