People who influenced Darwin
|
Anaximander, Lamarck (giraffs), Lyell (natural forces change the earth over long periods of time), and Wallace (published with Darwin)
|
|
|
Different types of evidence
|
Biogeography, comparative anatomy (homologous structures), comparative embryology, molecular biology
|
|
|
Hardy Weinberg Equilibrium
|
The frequencies of alleles will stay the same no matter how many times meiosis happens or how many times the alleles are put in different combinations.
|
|
|
Five Conditions of Hardy Weinberg
|
The population is large, the population is isolated, mutation does not affect the gene pool, mating is random, and all organsism are equal in reproductive success.
|
|
|
Genetic Drift
|
A change in the gene pool of a small population due to chance.
|
|
|
The Bottleneck Effect
|
Its genetic drift resulting from an event that drasticly reduces a populations size.
|
|
|
The Founder Effect
|
Its the colonization of a new location by a few individuals. The resulting gene pool is very small.
|
|
|
Gene Flow
|
When individuals move into or out of a gene pool.
|
|
|
Tools of Microevolution
|
Genetic drift, the bottleneck effect, the founder effect, gene flow, and mutation.
|
|
|
Tools of Macroevolution
|
Natural selection and variation.
|
|
|
Morphs
|
Different phenotypic characteristics in a population.
|
|
|
Neutral Variation
|
Variation in a heritable characteristic that exhibits no apparant selective advantage between individuals.
|
|
|
Darwinian Fitness
|
It measures how succesful an organism is at passing on its genes to the next generation.
|
|
|
Outcomes of Natural Selection
|
Stabilizing selection, directional selection, and diversifying selection.
|
|
|
Sexual Dimorphism
|
The physical differences, other than sexual organs, between sexes.
