  4. By the end of the lesson, you should be able to:  Explain how different adaptations in individuals of the same species may affect survivability or reproduction success.

    Slide 4 - By the end of the lesson, you should be able to: Explain how different adaptations in individuals of the same species may affect survivability or reproduction success.

    • State Standards:
    • S8.B.2.1 Explain the basic concepts of natural selection.

  5. Vocabulary

    Slide 5 - Vocabulary

    • Adaptation
    • Mimicry
  6. Warm-Up

    Slide 6 - Warm-Up

  7. Adaptation- A trait that helps an organism survive and reproduce.

    Slide 7 - Adaptation- A trait that helps an organism survive and reproduce.

    • Adaptations are well fitted to their function and are produced by natural selection.
    • Adaptations
  8. Mimicry: the close resemblance of an animal or plant to another animal, plant, or inanimate object.

    Slide 8 - Mimicry: the close resemblance of an animal or plant to another animal, plant, or inanimate object.

    • Mimicry of leaves by insects is an adaptation for evading predators.
    • Mimicry
  9. The creosote bush is a desert plant that produces toxins which prevent other plants from growing nearby, reducing competition for nutrients and water.

    Slide 9 - The creosote bush is a desert plant that produces toxins which prevent other plants from growing nearby, reducing competition for nutrients and water.

    • Example
  10. Echolocation in bats is an adaptation for catching insects.

    Slide 10 - Echolocation in bats is an adaptation for catching insects.

    • Example
  11. An adaptation is a feature produced by natural selection for its current function.

    Slide 11 - An adaptation is a feature produced by natural selection for its current function.

    • Adaptations
  12. If a trait has been shaped by natural selection, it must be genetically encoded.

    Slide 12 - If a trait has been shaped by natural selection, it must be genetically encoded.

    • Natural selection cannot act on traits that don’t get passed on to offspring.
    • Heritable
  13. If a trait has been shaped by natural selection for a particular task, it must actually perform that task.

    Slide 13 - If a trait has been shaped by natural selection for a particular task, it must actually perform that task.

    • Functional
  14. If a trait has been shaped by natural selection, it must increase the fitness of the organisms that have it

    Slide 14 - If a trait has been shaped by natural selection, it must increase the fitness of the organisms that have it

    • Natural selection only increases the frequency of traits that increase fitness.
    • Adaptive
