- 将变异与生存优势联系起来：具有有利特征的个体更有可能生存并繁殖
- Explain that variation within a species means some individuals have traits better suited to their environment
- Give examples of advantageous variations (e.g. camouflage, speed, drought resistance in plants)
- Connect variation to survival advantage: individuals with beneficial traits are more likely to survive and reproduce
