The 81st Annual Meeting of the American Association of Physical Anthropologists (2012)


Session 15. Not by Bread Alone: Non‐Caloric Determinants of Life History Strategies. Co-sponsored by the Human Biology Association and the AAPA. Invited Podium Symposium. Chair: Virginia Vitzthum and Pablo Nepomnaschy

Friday Morning, Galleria South Add to calendar

The role of energetics as a modulator of life history trajectories (e.g., the timing of developmental milestones and reproductive events, and the amount of effort invested in each reproductive venture) has garnered much attention from biological anthropologists. However, both life history theory and a growing body of empirical evidence suggest that factors not directly related to energy availability (e.g., mortality schedules, social dynamics, genotypes) can also play central roles in shaping life historystrategies (LHS) in humans and other primates. In this symposium speakers will examine both ultimate and proximate determinants of LHS and the mechanisms by which they contribute to variation in LHS. Talks will explore how genotypic variation, immune challenges, temporal changes in the cross‐talk between the HPA and HPG axes, and the social milieu affect ontogenetic trajectories and impact life history trade‐offs, thereby creating variation in life history trajectories and reproductive strategies. The symposium is intended to stimulate more research that contributes to developing a comprehensive understanding of the interplay of the various determinants of LHS in humans and other primates.
