Evolution

Concepts for Mastery

• Be able to describe the process of natural selection.  How does survival of the fittest affect the process of natural selection? Use Darwin’s finches as an example.

Know the graphs for

Stabilizing selection

Directional selection

Disruptive selection

• Be able to compare and contrast sympatric and allopatric speciation
• Be able to compare and contrast microevolution to macroevolution
• Be able to describe “ industrial melanism
• Be able to give examples and explain homologous structures, analogous structures, and vestigial structures.( Use the words convergent and divergent evolution with terms homologous and analogous)
• Explain these steps in speciation

Sexual isolation

Temporal isolation

Spatial isolation

Gamete incompatability

• Be able to explain the idea of allelic frequencies in regard to

Genetic bottlenecks ( what is a bottleneck and what effect does it have on genes in  a population?)

Genetic drift( When does it occur and what effect does it exert on the genes in a population?)

The founder effect ( This can result in unfit or deleterious genes occurring in abnormally high proportions in populations, Why?)

• Be able to explain what occurred in the population of Cheetahs that has led to its current problems
• How did this phenomenon affect the genes in the Almish populations or Ashkenazi Jews ?

describe the heterozygote advantage.  How does this relate to Sickle Cell Disease?

Be able to  compare and contrast the theories of evolution called

Punctuated Equilibrium and Gradualism ( Discuss extinctions in reference to Punctuated equilibrium)

Compare and Contrast Study Grid.  Use the study grid to construct the basis of essay questions for evolution
