Natural Selection Model 2: Environmental Conditions

Purpose

Find different environmental conditions that generate different trends in which number of flagella become more common over time due to natural selection.  For example, what conditions favor lots of flagella?  What conditions favor few flagella?

With a partner, discuss possible experimental conditions (in terms of %-resource-distribution or resource-location) that might generate these outcomes in the model. 

Use the model to test your ideas with at least three environmental conditions.

Questions

Please answer the questions below.

How did the %-resource-distribution and/or resource-location affect the average number of flagella of the bacteria?  Describe what you saw in each of the three conditions that you tested.

Based on your observations from the model, why do you think this was the case?
