 Genetic Drift is more likely to happen in... 

• aquatic populations
• small populations
• terrestrial populations
• older populations

This mechanism of evolution occurs when individuals migrate between populations.

• Extinction
• Gene flow
• Genetic drift
• Natural Selection

Which of the following is an example of natural selection?

• Bald Eagles are hunted until near extinction, population recovers.

• Small group of iguanas floats to an island, starts a new population.

• Red fox pups are more likely to survive in a snowy environment if they are born white.
