Roberto Schonmann: UCLA Department of Mathematics, Sao Paulo University Department of Applied MathThe evolution of cooperation and altruism are fundamental scientific challenges highlighted by their role in the major transitions in life's history, when natural selection acted simultaneously on several competing levels. The relevance of basic concepts, including group selection and Hamilton's rule remain nevertheless […]

Keise Izuma: Cal TechHuman behaviors are influenced by the concern for social reputation (e.g., how other people think of us). It is well known in behavioral sciences that individuals tend to behave in a more egoistic manner under guaranteed anonymity, whereas less anonymous situations (e.g., the presence of others) increase pro-social behaviors. These observations are […]

Heather Watts: LMUPatterns of survival and reproduction are known to be influenced by prevailing environmental conditions. In this talk, I will draw from my research on gregarious mammals and birds to examine how the social environment can affect these two components of fitness. First, I will discuss how social status, group size and maternal support […]

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: 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: 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: 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: 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: 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 […]
