Life history processes such as development, reproduction, and somatic maintenance contribute to an organism’s health and reproductive success. Although researchers across a number of fields have long recognized the importance of genetic, ecological, and physiological factors (e.g., hormones) that influence these processes, recent work indicates that the gut microbiome is a missing piece of the puzzle. The gut microbiome is established during infancy and can affect the development and function of host metabolism, the immune system, and the nervous system. Therefore, the microbes an individual is exposed to during this period can alter trajectories of energy allocation with direct implications for life history. Shifts in the gut microbiome may also facilitate specialized forms of energy extraction during energetically costly life history stages such as infancy, gestation, and lactation, and established effects of the gut microbiome on immune function may play a role in somatic maintenance and the pace of aging. Finally, the gut microbiome is an ecological community characterized by competitive interactions in which enrichment for certain microbial taxa and functions (e.g., energy extraction) may result in a loss of other taxa and functions. The physiological consequences of these dynamics may contribute to tradeoffs often referenced in life history theory. This symposium will highlight cutting edge research in areas of microbiome research relevant to life history, with the goal of integrating data from both humans and nonhuman primates, as well as from clinical and evolutionary perspectives. By encouraging dialogue among a diverse group of scientists, we hope to further advance this emerging field and contribute more broadly to our understanding of life history theory.
