Mechanisms
Genetic Draft
Individual leave by choice

Occurs because there is variation
Mutation
change in DNA
Microevoultion
change in gene frequency within population
occurs over short periods of time
evolution above species level
direct results
Macroevoultion
Evolution between the species level
small changes build up for over a million years
change in gene freaquency
direct results
