Alex Badyaev’s research focus is at the interface of evolutionary developmental biology and evolutionary ecology, with specific focus on the understanding of the origin of adaptations. The central goal of his work is to understand the evolution of organismal architecture that reconciles innovation and adaptation. Under this general umbrella, Badyaev lab studies the following empirical themes: 1) Origin, development, and evolution of avian color diversity, 2) Epigenetic remodeling and genetic adaptation in ontogeny of skeletal structures, 3) Relationship between epigenetic and genetic inheritance systems, 4) Role of stress in origin and diversification of organismal forms, 5) Evolution of behavioral and life history strategies, and 6) Evolution and ecology of sexual size dimorphism.Show Less
