BIO.SCI.10.B

Analyze and evaluate how the elements of natural selection, including inherited variation, the potential of a population to produce more offspring than can survive, and a finite supply of environmental resources, result in differential reproductive success.

Learning Targets
  • I can identify the elements of natural selection, including inherited variation, population potential, and environmental resources. #dok1
  • I can explain how these elements contribute to differential reproductive success in populations. #dok2
  • I can analyze the interactions between inherited variation, reproductive output, and resource availability. #dok3
  • I can evaluate examples of natural selection and determine how the described elements result in changes in populations over time. #dok3
Big Ideas
  • Natural selection acts on inherited variation within populations, resulting in differential survival and reproduction.
  • Key elements of natural selection—variation, overproduction, resource limitation—determine which individuals are most likely to survive and reproduce.
Essential Questions
  • What are the key elements of natural selection, and how do they interact?
  • How does inherited variation contribute to natural selection and evolutionary change in populations?
  • Why does natural selection affect populations rather than individuals?
  • What factors influence which individuals in a population are most likely to survive and reproduce?
  • How do environmental resources limit population growth and drive natural selection?
