1. Chapter 3: Genes, Culture, and Adaptation The Red Queen

2. Why Sex? -Men are Genetic Freeloaders

3. Why Sex? -Men are Genetic Freeloaders

4. Planet size piece of food. –The Red Queen Theory Striking a balance between genetic variability and function Universality of designs and- interchangeable parts Human genetic variability More genetic variability within populations than between populations

5. Population 1 Population 2 Number of Individuals Distance Between Pops Genetic Variation in Common

6. Population 1 Population 2 Number of Individuals Distance Between Pops Genetic Variation in Common

7. Population 1 Population 2 Number of Individuals Distance Between Pops Genetic Variation in Common

8. Physical Measurements (combined classes) What: Heights, Weights, limb and digit length Why? –Differences and Similarities Between Populations Adaptations to different environments –Phenotypic plasticity –Selection (Natural or Sexual) –Differences and Similarities Within Populations Access to resources –Status –Abilities

9. Types of Adaptation Genetic –Natural or Sexual Selection –Allen’s rule –Genetic tracking (the spear thrower and the archer) –Disease Resistance Mutation and HIV resistance HIV immunity –Malaria and Balanced Polymorphism Sickle cell and malaria

10. Evolutionary Medicine –Last Assignment –Pleiotropy Thrifty Gene theory (Neal) Senescence a byproduct or is there another reason - “Programmed Death” (telomeres)?

11. Physiological Adaptation Adaptive response to environmental factors Last as long as the individual is exposed to the environmental factor Shivering – to maintain body temperature (homeostasis) Altitude changes –Volume of Blood –More vascularization

12. Developmental Adaptation –Changes that occur during childhood development –Last a lifetime –Height

13. Cultural Adaptation Coca chewing Shelters Clothing Etc.
