Raziel Davison: University of California, Santa Barbara We investigate human life history evolution by comparing smallscale subsistence societies and chimpanzees to identify the roles that fertility and mortality play in driving population-level fitness differences. We discuss differences in the selection pressures facing individuals of different ages and to make inferences about the trajectory of human […]
Dan Hruschka: Arizona State University Replicating a study among our fellow humans requires a researcher to interact with study participants according to protocols that are comparable with previous studies. However, thanks to humanity’s rich capacity for cultural learning, it can be challenging to identify what counts as a “comparable protocol” across different human groups. Specifically, […]
Josh Snodgrass: University of OregonImmune function is an energetically costly physiological activity that can divert calories and other resources away from less immediately essential life history functions such as growth. However, direct evidence for immune-related tradeoffs among humans remains sparse. In this talk, I discuss longitudinal research among Shuar children (4-11 years old) that uses […]
