Big Ideas
  • Natural and artificial selection are processes that change the occurrence of traits in a population across generations.
  • The choices made by the environment or by humans impact which traits become more or less common in populations over time.
Essential Questions
  • What is the difference between natural selection and artificial selection?
  • How do natural and artificial selection change the traits found in a population over generations?
  • What are some real-world examples of how selection alters traits in populations?
  • Why might certain traits become more common or rare in a population as a result of selection?
  • How do natural and artificial selection influence the diversity of traits within populations?
