• 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

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

Types of Adaptation

• Genetic
• Natural or Sexual Selection
• Allens 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.
