EVOLUTION 


  One Student's View of Evolution
 

Evidence From Fossils
 
1. Define evolution. (P.571)
2. Compare the various ways in which fossils may form.(p.571-573
3. Evaluate the fossil record as an indicator of evolution. (P.571-573)
4. Discuss the relationship between the relative age of rock sediments the relative age of fossils contained within the rock layers. (P.573-581)
5. Appraise the methods of dating fossils by comparing the processes and accuracy of each method. (P.573-581).
6. Evaluate how each of the following acts as an indicator for a common ancestry or common design: (p.581-584, 605-609)
    i) comparative embryology.
    ii) comparative anatomy.
    iii) comparative biochemistry.
    iv) genetics.

Theories

1. Describe the theories put forward by Lamarck and Darwin (Wallace). (p. 599-604)
2. Compare the two theories and discuss why Darwin's theory became most widely accepted. (599-604)
3. Illustrate the sources of information that led Darwin to formulate his theory. (P. 599-604)
4. Outline the basic observations made by Darwin which enabled him to formulate his theory of natural selection.(p. 600-615)
5. Explain why Darwin was unable to account for the mechanism of inheritance of traits in his theory. (P. 603-607)
6. Illustrate how knowledge of Mendelian genetics and mutations supported Darwin's theory.

Evolution in Action

1. Give an account of the survival of peppered moths (industrial melanism) before, during, and after the industrial revolution; and show how it supports the concepts of natural selection. (P. 618-619)
2. Define species.(p. 128-130)
3. Explain the conditions under which speciation may occur. (P. 614-616)
4. Demonstrate how geographic isolation and reproductive isolation may contribute to speciation. (P. 614-616)
5. Evaluate adaptive radiation as a mechanism for speciation. (P. 614-616)
6. Explain convergent evolution and justify its occurrence in certain groups of organisms. (P. 616)
7. Make an analysis of the relative pace at which evolution may have occurred. (P. 603-604)
8. Examine the modern theories relating to evolution and give an account of each (e.g.. Gould and Eldredge). (p. 602-604)
9. State the Hardy-Weinberg law and explain its significance in terms of the development of evolutionary theories. (P. 607-609)

Origin of Life

1. Explain at least TWO of the early theories on the origin(s) of life.
2. Explain the following:
    i) Intelligent design
    ii) Gaia hypothesis
    iii) Lynn Margulis Hypothesis
    iv) Spontaneous generation
2. Appraise the Haldane-Oparin hypothesis and the Miller-Urey experiments and show how the Haldane-Oparin hypothesis is strengthened by the Miller-Urey experiments.
3. Identify the conditions that are thought to have been optimal for the origins of life. (P. 589-593)
4. Present an argument for whether prokaryotic or eukaryotic cells existed first and collect evidence to support your findings. (P. 589-593)
