Sample Content for an Evolution Natural Selection Worksheet
Below is an outline of typical questions and activities that might be included in an effective worksheet:
Section 1: Vocabulary and Definitions
Define the following terms:
- Evolution
- Natural Selection
- Adaptation
- Fitness
- Genetic Variation
Section 2: Concept Explanation
Explain in your own words how natural selection leads to evolution. Include the key steps involved in the process.
