Natural Selection Webquest

1. BEFORE STARTING THE WEBQUEST, PLAY THE ANTIBIOTIC GAME.

2. THEN TRY THIS ACTIVITY ABOUT INTERPRETING FOSSIL FOOTPRINTS

3. THEN TRY THIS ACTIVITY ABOUT THE PROCESS OF FOSSILIZATION.

4. THEN TRY THIS ACTIVITY ABOUT HOW CAMOFLAGE HELPS PREDATOR AND PREY SURVIVE.

5. THEN TRY THIS ACTIVITY ABOUT PUTTING TOGETHER FOSSIL SKELETONS.

6. AND THIS ONE ABOUT THE PROCESS OF FOSSILIZATION.




NATURAL SELECTION WEBQUEST.
PART 1. ANTIBIOTIC RESISTANCE
1. WATCH: WHY DOES EVOLUTION MATTER NOW?
Go to Microbe Clock Interactive.
How do humans influence the evolution of microbes?


How does natural selection work to produce multi-drug-resistant tuberculosis?


Why is understanding evolution especially important today, now that people can travel easily?


EVOLUTION OF THE EYE
Watch the Evolution of the Eye video
Why were people resistant to the idea that the eye evolved through natural selection?

What evidence can you give to show that evolution did occur through natural selection? (For example, some animals alive today have simpler stages of the eye; Nilsson's work shows how the evolution could take place through small changes, etc.)


Why has the flatworm not evolved a more complex eye with a lens?




SEXUAL SELECTION:
Try the The Mating Game Web feature, and watch Sweaty T-shirts and Human Mate Choice video.


What role does sexual selection play in natural selection?



Why have male competition and female choice evolved as a selection means in many species? What role does partner selection play in genetic diversity?

SEXUAL SELECTION VS. NATURAL SELECTION:
TRY THE SEX AND THE SINGLE GUPPY http://www.pbs.org/wgbh/evolution/sex/guppy/
What hypotheses did you test?


What conclusions did you reach based on your simulation results?


How do sexual selection and natural selection interact in this guppy simulation? In nature?
