Natural Selection Simulation
🧬 Part 1: Understanding Natural Selection
1. What is variation in a population?
All organisms look exactly the same
Organisms have different traits within the same species
Only one organism survives
All organisms die
2. Which factors are necessary for natural selection to occur? (Check all that apply)
Variation in traits
Competition for resources
All organisms are identical
Reproduction of survivors
3. In a drought environment, which bird trait would most likely be advantageous?
Bright colorful feathers
Large beak for cracking hard seeds
Very small wings
Loud singing voice
4. Fill in the blanks: Natural selection occurs when organisms with __________ traits are more likely to __________ and pass those traits to their __________.
Word bank: offspring, survive, beneficial, harmful
🔬 Part 2: Simulation Analysis
5. Based on your simulation activity, describe what happened to the population when the environment changed from forest to desert.
6. Explain why some organism tokens "survived" while others were removed during the simulation.
7. How did the traits of your population change over the three generations? Use specific examples from your simulation.
🌍 Part 3: Real-World Connections
8. Predict what might happen to a population of white rabbits if their snowy environment suddenly became brown and rocky due to climate change.
9. True or False: Individual organisms can change their traits during their lifetime to better survive in their environment.
True
False
Explain your answer: _________________________________________________
10. How does natural selection cause populations to change over time? Use evidence from today's activity to support your answer.
