In this episode we cover the patterns of Natural Selection:
Directional: An extreme version of a trait is favored in the population.
Stabilizing: The intermediate or average form of a trait is favored.
Disruptive: The two extremes are favored, while the intermediate is selected against.
Fluctuating: A trait fluctuates based on periodic changes in the environment
Balancing: When multiple versions of a trait are supported in a population.
