Evolutionary Approaches to Health Issues and Behaviors Across the Life Course
Health-related research is broad, diverse, and fragmented theoretically, methodologically, and across disciplines. The understanding and improvement of human health would be accelerated by establishing a universal and deep framework integrating varied undertakings. This framework is evolutionary theory, the most powerful explanatory system in the life sciences and the only framework that can unify knowledge in otherwise disparate fields of human research. Darwinian medicine has already made considerable progress in the practical understanding of human physiology and other areas informing medical care. Within evolutionary theory, life history theory in particular holds the promise of promoting understanding of variation in behavioral patterns related to health and why they vary consistent with environmental conditions. This chapter describes the current state of research exemplifying an evolutionary approach to health-related psychology and behavior and outlines directions for future research and intervention efforts.
