Modeling Natural Selection

Today students modeled natural selection with the Clipbirds Investigation. 

Tomorrow G period will complete this activity and C period will begin to learn about speciation.

Below are the analysis questions that G period needs to complete for homework:

1. Identify any patterns you see in the results.
2. Explain the relationship between food source and beak size.
3. What do you think would happen if between the 3rd and 4th seasons, there was a drought in East Clipland that resulted in fewer large seeds, but more smaller seeds?
4. Explain how this activity demonstrates natural selection.  First define natural selection.
5. Do you think that 1000 years from now, these birds would still be part of the same species?  Explain your answer in a paragraph.
