1. Briefly describe the
evolution of life from chemical evolution to the development of eukaryotic
2. Describe the tools
available to researchers for learning the evolutionary history of life.
3. Briefly describe the
theory of evolution, being sure to include the roles played by variation within
the gene pool and natural selection, extinction, speciation, and adaptive
4. Define natural
selection and the three conditions that are necessary for evolution of a
population by natural selection.
Summarize and address two common misconceptions about evolution.
5. Define coevolution.
6. Distinguish between
a specialist and a generalist. Evaluate the conditions that favor these two
7. Define ecological niche. Distinguish between condition and resource; fundamental niche and realized niche. List the factors that determine the realized
8. Define speciation and
compare allopatric speciation with sympatric speciation. Indicate which of these mechanisms is more
9. Define extinction
and distinguish between background extinction and mass extinction. Discuss the
role of humans on the rate of extinction at present.
10. Discuss the pros and
cons of artificial selection and genetic engineering. Consider the possible environmental impacts
on resource use, pollution and environmental degradation.
11. Indicate what it is
that has allowed humans to have such a profound influence on their environment.
