• Ex: When flowers from one side of the river transports pollen to flowers on the other side.

MUTATION

• A random change in DNA affecting looks and behavior
• Ex. A fly with no wings

NATURAL SELECTION

• Gradual process by which traits become more or less common in population
• Ex: butterflies choose a mate that helps camouflage.
