Match the mechanism to the correct definition. (pop. = population)

• large part of pop. dies rapidly/randomly

• Speciation

• fittest to survive and reproduce

• Gene flow

• Change in genes, adds variation

• Mutation

• formation of new species

• Bottleneck effect

• pop. move to other pop. to add variation

• Natural Selection
