Big Ideas
  • Variations in characteristics among individuals of the same species can provide certain individuals with advantages in survival, finding mates, and reproducing.
  • Using evidence helps us understand how differences among individuals can lead to differences in how well they survive, reproduce, or find mates.
Essential Questions
  • How can small differences among individuals of the same species help them survive in their environment?
  • Why might one animal be better at finding food or mates than another of the same species?
  • What evidence can we find that shows certain traits help individuals survive or reproduce?
  • How do variations in characteristics influence which animals thrive in their habitats?
  • What happens to a species if individuals with certain variations have more offspring?
