Exercise 4: Scenario Analysis
Read the following scenario and answer the questions that follow it.

Scenario: A population of butterflies lives in a forest where the trees have dark bark. Over time, the butterflies that are darker in color have a higher survival rate due to better camouflage from predators.

Questions:
1. Which mechanism of evolution is primarily illustrated in this scenario?
2. What role do mutations play in the adaptation of the butterfly population?
3. How might this scenario lead to speciation in the future?

Exercise 5: Reflective Writing
