Facial Fluctuating Asymmetry: Developmental Origins And Implications For Long-Term Health, Katelyn Marie Rusk Phd

Anthropology ETDs

Fluctuating asymmetry (FA), characterized by random left-right deviations from perfect symmetry in anatomical structures, is a form of bilateral asymmetry that is thought to reflect underlying developmental instability (DI). DI refers to an organism’s relative ability to buffer against stochastic fluctuations in environmental conditions throughout development. FA is commonly used within evolutionary biology and anthropology as a cumulative indicator of chronic stress exposure during development and its consequences for long-term health. While the FA literature is extensive, there are two primary areas of inquiry that remain incomplete: assessing the full breadth of health correlates of FA across the human life …
