✅ Short answer prompts—5 questions—to assess understanding of mutation, genetic drift, and natural selection
✅ PDF worksheet and PDF answer key with rubric for easy printing and assessment

Key Concepts Covered

➡️ Evolutionary mechanisms – Understanding how genetic variation and forces like natural selection, mutation, genetic drift, and gene flow drive evolutionary change
➡️ Genetic variation – The role of mutations and recombination in creating diversity within populations
➡️ Natural selection – How differential reproductive success shapes species over time
➡️ Genetic drift – Random changes that have significant impacts, especially in small populations
➡️ Mutation – The process responsible for creating new genetic material, acting as the source of genetic variation
