Natural Selection EOC Review

In a population of clover flowers, there are both white and purple varieties. The cows that graze the field where the clover grows prefer the purple variety. Over time, the white clover flowers become much more numerous and the purple ones more scarce. This is an example of which process that can cause evolutionary change?

• genetic equilibrium

• genetic mutation

• natural selection

• overproduction

In a population of beetles, some are green and some are brown. Birds can easily spot the green beetles against the brown soil, leading to more green beetles being eaten. Over time, the population has more brown beetles. What process is this an example of?

• Gene flow

• Mutation
