Variation & Survival Advantage
变异与生存优势
Description
Use evidence to explain how variations in characteristics among individuals of the same species may provide advantages in surviving, finding mates, and reproducing
Mastery Evidence
- 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
Assessment Prompt
Can your child explain why a faster rabbit in a group might survive longer because it can escape predators better than slower ones?
