The Bigger Question!

Directions: Answer the question below on a separate sheet of paper and turn it into the appropriate period homework turn in slot. 


          Pick an organism of your choosing (except for the Peppered Moth) and create an environment for it. Then I want you to discuss how natural selection, of your own choosing, acts on that organism. Speculate what would happen to your organism if a natural disaster occurred (either an earthquake, a flood, or a fire) . Would the tides of natural selection change? Explain your answer.
