Martin Muller – Behavioral Ecology and Socioendocrinology of Reproduction in Male Chimpanzees

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 […]

Dawn Neill – Roti or Ramen: The Behavioral Ecology of Food Choice among Rural and Urban Indo-Fijians

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 […]

Colin Holbrook – Why Thoughts of Death or Isolation Magnify Group Prejudice

Colin Holbrook: UCLAHumans are inclined to cherish their communities and derogate groups regarded as alien, particularly during times of threat. The capacity for threatening circumstances to exacerbate group prejudice holds both social relevance and theoretical interest, and has been widely discussed within psychology and evolutionary anthropology. Perhaps the most intensively studied experimental measure of group […]

Sergey Gavrilets – On the evolutionary origins of the egalitarian syndrome

Sergey Gavrilets: University of TennesseeHumans exhibit strong egalitarian syndrome, i.e. the complex of cognitive perspectives, ethical principles, social norms, and individual and collective attitudes promoting equality. The universality of egalitarianism in hunter-gatherers suggests that it is an ancient, evolved human pattern. The evolutionary emergence of this syndrome is one of the most intriguing unsolved puzzles […]

Robert Frank – Rivalry and Cooperation: A Darwinian Perspective

Robert Frank: CornellNote: this talk will begin at 3:30pm. Economists since Adam Smith have insisted that competition produces the greatest good for the greatest number. But as Charles Darwin emphasized, individual and group interests do not always coincide. And when they clash, individual interests tend to trump, often resulting in wasteful arms races. The Darwinian […]

Clark Barrett – Confronting the puzzle of evolutionary novelty

Clark Barrett: UCLAThe capacity of organisms to deal with evolutionary novelty has been regarded by some as a puzzle. If adaptations have been shaped by natural selection operating in the past, then how can they possibly respond adaptively to objects, events, and situations that clearly did not exist until recently? This has been regarded as […]

Adrian Jaeggi – Food sharing in human and non-human primates

Adrian Jaeggi: UCSBFood sharing is a vibrant field of study that has provided important insights into the evolution of cooperation, life history, and social learning. Common functional explanations for sharing include nutritional and informational benefits to offspring, tolerated scrounging, kin selection, reciprocal altruism, and costly signaling. I review the most important findings regarding food sharing […]

Jeff Snyder – He Would Never Hurt Me: Women’s Preferences for “Tough Guys”

Jeff Snyder: UCLAIn general, women in the U.S. appear to prefer prestigious men to dominant men under most circumstances. However, some women select domineering men as long-term intimate partners – sometimes at a high cost to themselves. Such women are likely sensitive to their self-perceived vulnerability to danger, and hence may select domineering men when […]

Hanah Chapman – Moral Disgust Discussed: Emotional and Cognitive Contributions to Human Morality

Hanah Chapman: Ohio State UniversityBeing lied to, cheated upon, stolen from—these are among life’s most emotional experiences, and even watching them happen to someone else can trigger strong feelings. Recent work has confirmed the important role of emotion in human morality, but less is known about precisely which emotions are involved and how emotion exerts […]

Hillard Kaplan – Tsimane Aging and Human Life History Evolution

Hillard Kaplan: The University of New MexicoThis talk examines what we have learned about the aging process among Tsimane forager- horticulturalists, and the implications of our results for understanding human life history evolution. I review our latest findings on behavior, inter-generational transfers, physical function, immunocompetence and cardiovascular disease. Tsimane men and women remain net producers […]
