MS-LS4-4: Construct an explanation based on evidence that describes how genetic variations of traits in a population increase some individuals’ probability of surviving and reproducing in a specific environment.
Objectives
1. Students will explain how cold environments can change the distribution of the fur trait in the ostrilope population to favor adaptive traits, and get rid of non-adaptive traits after 50 generations by answering question 12 in their handout using all of the required vocabulary words correctly.

Natural Selection
Common Ancestor
Specialized
Environmental Pressures

Non-Adaptive Trait
"Survival of the Fittest"
Questions
1. How did Charles Darwin develop his theory of evolution?
2. Why did the birds on the Galapagos Islands have differently shaped beaks?
3. Explain how environmental pressures make it difficult for organisms to survive.
4. How can mutations cause differences in variations?
5. How can mutations be bad for an organism's survival?
6. How can mutations be good for an organism's survival?
7. What is the "neat" consequence of the Theory of evolution?
8. Explain Darwin's tree analogy for the diversity of life.
Summary: (you may use bullet points, a paragraph, or draw)
Today I learned....
3. When you are finished, you may:
-watch THIS DOCUMENTARY about human evolution
- watch THIS DOCUMENTARY about how the theory of evolution has changed through time to become more accurate.
- Play the first level of the evolution game
- Play the fossil sorting game
