1. List the five conditions that must be true for a population to be in HardyWeinberg
equilibrium. Why is it useful to know the conditions that prevent evolution? For each
condition, specify whether violation of that assumption results in changes in genot
1. Review the kinds of evidence for evolution analyzed in Sections 2.12.5. List the sources of
evidence that were available to Darwin and those that appeared later. For example, of the
evidence for microevolution discussed in Section 2.1, Darwin knew, and
1. What is the difference between genetic variation, environmental variation, and
genotype-by-environment interaction? Give examples of each. Try to think of potential
examples not covered in this chapter.
5. Consider the nucleotide sequence TGA
2. Review the process by which the HIV population inside a human host evolves resistance to the
drug AZT. What traits of HIV contribute to its rapid evolution? How might a similar scenario
explain the evolution of antibiotic resistance in a population of
How does variation relate to the struggle for existence?
How does Darwin define the struggle for existence?
Expand on Darwins definition of Natural Selection?
Explain without profitable variations, Natural Selection can
