Lab 3: Evolution by Natural Selection

In this lab, you will explore two different simulations that explain how evolution by natural selection works, both on short and long term scales. For each simulation, you’ll have a series of questions to answer at the end. As for previous labs, you will want to take good notes along the way so that you can answer the questions at the end more easily. A. Go to the Darwin survival game at the following link:

[the game does not work well on my Firefox browser, but works well in all other browsers I’ve tried, such as Chrome or Internet Explorer]

- Press the “Natural Selection” tab and complete the quick simulation - Play the “Survival Game”. I suggest playing it 3-5 times to get a good idea of how it

works; take notes along the way, keeping track of your different organisms, which one was most successful and why, which one lived the longest, whether you won (and if not, how long did you last).

- Click on “Darwin’s Bio” tab and read the text - Take the quiz; keep track of the questions, esp. if you find some of them difficult,

and keep track of what it tells you at the end of the quiz.

When you are finished, answer the following questions about this activity.

1. Are all organisms within a species typically identical? Why or why not? Justify your answer using your notes from the “Natural Selection” tab and from the game you played.

2. What happens to traits that are beneficial for an organism? To traits that are detrimental to the organism? Justify your answers using your notes from the game you played. Where do these traits come from?

3. Did you win any of the rounds of the game you played? If not, what was your oldest organism? What did it look like, and why was it more successful than others?

4. Describe the process happening during the game. Are the different organisms different species, or different variants within a species? Why does this matter? Justify your answer.

5. Based on your experience in playing this game, do you think there have been more extinctions of species than successes of various species? Explain.
