Michelle Kline: The University of California, Los AngelesHumans are heavily reliant on cultural adaptation, and have coevolved with culture for millennia. Teaching enhances the fidelity of cultural transmission and should be common in such a culture-dependent species. However, existing data present a puzzle concerning the role of teaching in human evolution. While biologists have documented […]

Lucia Jacobs: University of Caliornia, BerkeleyThe chemical senses of vertebrates present some of the most enduring mysteries of brain evolution. First, it is not clear why are there two olfactory systems: the main system (MOS), detecting odorants on the olfactory epithelium and projecting to the olfactory bulb, and the accessory system (AOS), detecting odorants in […]

Rich Connor: University of Massachusetts DartmouthFor over 25 years we have documented a multi-level alliance structure among male bottlenose dolphins in Shark Bay, Western Australia. Males cooperate in pairs and trios, ‘1st-order alliances,’ to form temporary consortships with individual females. First-order alliance partners are drawn from a male’s second-order alliance. Second-order alliances have 4-14 males […]

Nancy Segal: California State University, FullertonAn overview of the origins, methods, findings, implications and controversies from the Minnesota Study of Twins Reared Apart is provided. This study, which took place between 1979 and 1999 at the University of Minnesota, accumulated a wealth of behavioral, physical and medical data on 137 reared apart twin pairs, 81 […]

Paul Heggarty: 4:00 PM Cotsen Institute Room A222From the Tower of Babel to the tales of the Aboriginal Dreamtime, we have long sought to account for our baffling multiplicity of tongues. Linguistic science itself was born out of this curiosity — and by now can look to our language diversity no longer as just an […]

Jennifer Hahn-Holbrook: University of California, Los AngelesPostpartum depression poses an evolutionary puzzle: it is extremely common, yet significantly reduces the reproductive fitness of both mothers and children. Why has natural selection failed to remove this trait? I will consider the hypothesis that postpartum depression represents a “disease of modern civilization” – that is, a byproduct […]

Bailey House: University of California, Los AngelesOne explanation for the diversity in cooperative behavior across human social groups is that our prosociality is motivated in part by learned cultural beliefs that vary substantially across societies, and which extend adaptations for cooperation between genetic kin and reciprocal partners. Reframing this idea as a developmental question about […]

Claire White : California State University, NorthridgeGrief is a universal reaction to the loss of a valued relationship partner. Two main evolutionary accounts of grief have been proposed. The first views grief as a by-product of an adaptive separation reaction that functions to aid unification in the temporary loss of a valued relationship partner. The […]

Steven Stroessner: Barnard College, Columbia UniversityMotivations are generally concerned with maintaining safety (prevention) or ensuring advancement (promotion) (Regulatory focus theory; Higgins, 1997). Four experiments examined whether information implying imminent threat would interact with regulatory focus to affect endorsement of stereotypes and stereotype-based policies. Because threatening information is more relevant to the safety goals of prevention-focused […]

Monique Borgerhoff-Mulder: University of California, DavisWhile the causes, transmission and consequences of material and social inequality are well studied in the social sciences, the ways in which people respond to inequality are less clear. As evolutionary social scientists we know that humans show a strong aversion to inequality, but we have little understanding of how […]
