An activity in class that shows how natural selection works. Students create offspring with genetic diversity, and nature chooses the organism best adapted to survive and reproduce. Over thousands of generations (5-6 rotations) a new species develops.

1. Daily Stimulus #30 What is the difference between artificial selection and natural selection? (MyWay p.50)

6. Artificial Selection Mankind chooses and breeds an organism, selecting it for a trait that it desires.

7. Natural Selection Only the organisms with the best genes survive and reproduce to pass on their genes. After many many generations, the species changes into something new.

13. Natural Selection (Classroom) p.54 1) Draw your original creature 2) Draw what it looks like after thousands of generations 3) Explain: How did your creature change? 4) Explain: Why did your creature change? What basic need does it get better now?
