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?
