Description
Lecture 1: Key Concepts of Adaptability Research January 9, 2012 1. Humans are part of nature (ecological systems) and subject to the same evolutionary processes, and exhibit tremendous variation in response to environmental influences 2. External stresses (environmental, social, nutritional, epidemiological, psychological) have measurable effects on human physiology and well-being 3. Humans are the most plastic species in nature, mostly because of cultural adaptations (phenotypic plasticity) 4. The nature of developmental acclimatization and dysfunction, particularly during infancy and childhood, when stress is most intense, is vital in understanding human adaptive capacity and flexibility in later years 5. Cross-culturally, the health and well-being of humans ultimately reflect the state of external socio-economic, political and ideological systems Human, Genetic, Plastic, and Developmental System Biotic Environment  Food, pathogens, materials, symbionts and predators Physical Environment
