Natural Selection Model 1: Predation


Let's look now at a different version of the bacteria flagella model that we used in the last lesson. 

In this model, you are a predator. You can kill bacteria by moving the mouse cursor over and clicking.

Make sure to choose "none" from the VISUALIZE-PHENOTYPE menu, then set up the model and click on the button "run one minute experiment". The model will run for one minute. Try to kill as many bacteria as you can in that one minute.  After the time is up, choose "flagella and color" from the VISUALIZE-PHENOTYPE menu. And click on "visualize" button. 

Note your observations in the space provided below after you finish the experiment.

 


Questions

Please answer the questions below.

Repeat the experiment twice. Write the number of bacteria of each variation at the end of the simulation run.


What pattern do you notice in your results?  Explain your observations.
