    3. Lesson 3.3 - Natural Selection, Speciation & Pattern of Evolution

    Lesson 3.3 - Natural Selection, Speciation & Pattern of Evolution

    • Lesson 3.3 - Natural Selection, Speciation & Pattern of Evolution

      Lesson 3.3 - Natural Selection, Speciation & Pattern of Evolution

      Learning Goals: By the end of this lesson you will be able to

      1. define Key Terms: 8.1 (directional selection, stabilizing selection, disruptive selection, sexual selection, genetic drift, genetic bottleneck, Hardy-Welnberg principle); 8.2 (microevolution, speciation, reproductive isolating mechanism, prezygotic mechanism, allopatric speciation, sumpatric speciation); 8.3 (adaptive radiation, divergent evolution, convergent evolution, coevolution)
      2. compare and contrast, with examples and diagrams, Directional, Stabilizing and Disruptive selections
      3. fully descrive the importance and impact of Sexual selection
      4. explain the natural selective pressures involved in specific traits of organisms (i.e. acute vision of hawk; refere to table 1, p. 329)
      5. describe an example of cumulative selection
      6. describe Genetic Drift and the impact of Bottleneck effects
      7. describe an example of the impact of human acrtions on the evolution of a species
      8. explain, with examples, all types of Pre- and Postzygotic methods of reproductive isolating mechanisms
      9. compare and contrast Allopatric and Sumpatric speciation
      10. describe, with examples, Adaptive Radiation, Divergent/Convergent/Co-Evolution
