Answer the following questions (p106-111)
What argument does Monte Verde produce? Reasons/Evidence
List the ways humans migrated to America. Explain/Details
What does the Olsen Chubbuck site suggest about hunting patterns?
We’re Coming to America!!!
Human VariationWhy are there physical differences?
Natural Selection Directional shift
Average value will shift because it is beneficial. (Skin) Normalizing Selection
Average value will not shift, but the extremes are removed.
Balancing Selection Heterozygous (different) combinations of alleles is favored.
Genetic Drift Removal of less frequent “neutral” genes from isolated
groups.
Process of Human Variation
Gene Flow Passing of genes from one population to
another. Decreases differences.
Cline – variation in frequency
Influence of the Environment Climate may influence growth and
development Influence of Culture
Modifications to life may affect genetic adaptations.
Take notes on the following from Ch. 7
Body Build Facial Construction Skin Color Adaption to High Altitude Height Infectious Diseases Sickle-Cell Anemia Lactase Deficiency
Variation in Populations
Body Build Bergman’s Rule
Body size and temperature. Allen’s Rule
Length of limbs based on temperature/climate Facial Construction
Size of the nose based on climate (humid – short flat nose) Skin Color
Gloger’s Rule People living in warmer climates have more melanin.
Adaption to High Altitude Theory of larger chests, greater lung capacity.
Variations in Population
Height Temperature Nutrition
Infectious Diseases Develop inherited resistance to diseases.
Sickle-Cell Anemia Abnormality of red blood cells. (connection w/
malaria) Lactase Deficiency
Inability to digest lactose (temperate climates)
Variations in Population
Race Classificatory way to describe population variants.
Racism Belief that some races are inferior to others.
Misused and misunderstood (associated with racist thought)
Product of adaptive traits Traits that happen because of natural selection
tend to cluster in regions.
Race - Biological
Used to describe groups. Discriminate Make groups Superior/Inferior Developed Nations
White Underdeveloped Nations
Other
Race Social
European Advance Formed later civilizations Colonized much of the world Brought diseases (killed natives)
Racial Intelligence Whites are genetically smarter (belief)
Alpha Beta IQ test. IQ Tests
Not accurate IQ influenced by social environment
European Advance Racial Intelligence

Genetic Engineering to replace maladaptive traits.
SUPERHUMAN!!!!!!!!!!!!!!
