Lesson 3.3 - Natural Selection, Speciation & Pattern of Evolution
Learning Goals: By the end of this lesson you will be able to
- 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)
- compare and contrast, with examples and diagrams, Directional, Stabilizing and Disruptive selections
- fully descrive the importance and impact of Sexual selection
- explain the natural selective pressures involved in specific traits of organisms (i.e. acute vision of hawk; refere to table 1, p. 329)
- describe an example of cumulative selection
- describe Genetic Drift and the impact of Bottleneck effects
- describe an example of the impact of human acrtions on the evolution of a species
- explain, with examples, all types of Pre- and Postzygotic methods of reproductive isolating mechanisms
- compare and contrast Allopatric and Sumpatric speciation
- describe, with examples, Adaptive Radiation, Divergent/Convergent/Co-Evolution
