Population genetics and evolution
Population genetics
Factors of gene pool change
Mutation
Accident
Artificial selection
Natural selection
Other factors
Natural selection š« Operate
All species are genetically identical
Survival is universal
Impossible to adapt to certain condition
Selection pressures
Many attacks at once
Rates of evolution
Not usually rapid change
Speciation
Phyletic
Pollen transfer
Seed dispersal
Vegative propagation
Divergent
Abiological reproductive barriers
Biological reproductive barriers
Adaptive radiation
Convergent
Will eventually strongly resemble each other
Evolution and origin of life
Conditions on earth before life
Chemicals before atmosphere
Energy source
Time available
Chemicals produced chemosynthetically
Formation of polymers
Ocean from dilute to concentrated
Aggregation & organization
First at random
Early Metabolism
Complete heterotrophs
Oxygen
Aerobic respiration
Rust
Oxidizing atmosphere
Presence of life
Long series of slow gradual transitions
