Who is Darwin, what did he do, and why does it matter?

Darwin, HMS Beagle, Galapagos Islands, Natural Selection, Common Descent
What is selection (natural and artificial) and why is it important?

Natural Selection, Variation, Fitness, Adaptation, Descent with Modification, Environment, Artificial Selection
What are the different lines of evidence for evolution and what do they mean?

Evolution, Fossil Record, Comparative Anatomy [embryology, homologous, analogous, vestigial], Biochemical
Evidence, Radiometric Dating Evidence
Explain the four basic mechanisms of evolution and use an example of how they would affect a certain
population.

Mutation, Migration, Genetic Drift, Natural Selection, Variation
How does genetics factor into evolution?

Evolution as a change in allele frequency. Genetics explains sources of variety such as camouflage or mimicry,
within species, coming from gene shuffling and mutations, and these beneficial genetic variations are passed
down through natural selection.
How does natural selection affect allele frequency?

Natural selection can either be directional (pushing one direction towards greater fitness), stabilizing,
(removing variety to increase populations fitness), or disruptive (separating towards two species with greater
fitness in their own niche). This can be graphed and measured with respect to allele frequency.
What is speciation?

Species are a population that can interbreed with one another. If this population experiences reproductive
isolation (geographical, behavioral, temporal) and the mechanisms for evolution are all present, then the
population can split into multiple different species.
