Sarah Mesnick: Southwest Fisheries Science Center, NOAA Fisheries ServiceKnowledge of the genetic structure of social groupings provides the basis for understanding the relative influences of kin selection and reciprocity in the evolution of individual behavior and for understanding the basis of population structure, which is important for conservation. Sperm whale, Physeter macrocephalus, groups comprised of […]

Ivy Pike: University of Arizona Department of AnthropologyGrowing efforts to carefully link social environments to biological experiences have emerged in many disciplines; Anthropology is no exception. This integrative perspective aims to place bodies in context with a strong awareness of the role gradients of inequality play in shaping population variation in health. While much anthropological […]

Michael McCullough: University of Miami Department of PsychologyExploitation—the targeted infliction of fitness costs on another organism for the purpose of capturing benefits for the self—is a fact of life for social organisms. Because of its pervasiveness in social life, natural selection gives rise to deterrence mechanisms (e.g., thorns, toxins, defensive weaponry) designed to alter potential […]

Edward H. Hagen: Washington State University Vancouver Department of AnthropologyCurrent neurobiological theory of recreational drug use is based on the observation that all addictive drugs induce changes in activity of dopaminergic circuitry, interfering with reward processing, thus enhancing drug seeking and consumption. On this view, recreational drugs "hijack" evolved reward circuitry. Current theory of drug […]

Christopher von Rueden: UCSB Department of AnthropologyThe relationship between social status and reproductive success in small-scale societies can provide insight into how natural selection may have acted on status-seeking behavior in ancestral human environments. With data from the Tsimane horticulturalists of Bolivia and other small-scale societies, I show that high male status increases lifetime fitness, […]

Andrew Delton: UCSB Department of Psychology and Center for Evolutionary PsychologyMembers of social species routinely make decisions that involve welfare allocations—decisions that impact the welfare of two or more parties. These decisions often involve welfare tradeoffs such that increasing one organism’s welfare comes at the expense of another organism’s welfare. In this talk, I present […]

Polly Wiessner: University of Utah Department of AnthropologyIndoctrinability, the capacity to be inculcated with values or doctrines and to accept them uncritically, poses an evolutionary puzzle because it can lead individuals to voluntarily sacrificing immediate individual interest for a belief, cause, or group. I will briefly explore the cognitive capacities underlying indoctrinability. Then I will […]

Daniel M.T. Fessler: UCLA Department of AnthropologyThe evolutionary study of mind and behavior has benefited enormously from the functionality heuristic, i.e., the assumption that mental mechanisms can usefully be understood as well-designed solutions to recurrent adaptive problems. While virtually every investigator in this area acknowledges the importance of Tinbergen’s (1963) Four Levels of Explanation, in […]

Siobhán M. Mattison: Stanford University Department of Anthropology and Morrison Institute for Population and Resource StudiesThe study of kinship is foundational to anthropology. Though interest in kinship waned briefly, it has recently been rekindled, particularly in the area of evolutionary ecology. In this talk, I review briefly the major trends in anthropological thought on kinship […]

Peter Nonacs: UCLA Department of Ecology and Evolutionary BiologyHamilton’s theory of inclusive fitness broadly states that whether or not a trait increases in frequency is dependent on both the direct reproductive success of individuals having that trait and the help that such individuals can provide to other trait bearers for their reproduction. The latter portion […]
