The 84th Annual Meeting of the American Association of Physical Anthropologists (2015)


Session 1. Energetics in Human and Non-Human Primate Evolution: Moving from Theory to Empirical Tests. Invited Podium Symposium. Chair: Christopher Kuzawa

March 26, 2015 , Grand Ballroom D Add to calendar

The remarkable diversity in primate life histories reflects differences in the quantity of energy and metabolic resources available within the body, and the priority with which energy is allocated across the key functions of growth, reproduction, activity and maintenance. Energetics lies at the heart of questions cutting across the subfields of Biological Anthropology: How do ecological pressures such as climate and foraging effort affect energy throughput? When and how does energy expended on activity, thermoregulation, immune function, or other tasks affect the pace of growth, reproduction, and aging? What are the constraints on energy allocation and how have these shaped the evolution of life cycles?  How does the body manage acute trade-offs between competing functions, and what are the implications for phenotypic diversity within and across populations?  What are the social dimensions of energy flow and what are their roles in reproductive strategies?  Recent methodological advances have enabled anthropologists to move beyond simple models of energy expenditure to empirical tests of energy allocation in humans and other primates, from the lab to the field, and even in skeletal and fossil remains. This session will bring human biologists, paleoanthropologists and primatologists together to explore the role of energetics in the evolution of human and non-human primates.
