Ch. 25 Tracing Phylogeny: Macroevolution, Fossil Record, Systematics

  1. Distinguish between relative dating and absolute dating
  2. Explain how preadaptation can result in macroevolutionary change
  3. Explain how modification of regulatory genes can result in macroevolutionary change
  4. Describe importance of evolutionary trends to macroevolution
  5. Describe the contributions of Carolus Linneaus made to biology
  6. List major taxonomic categories from most to least inclusive
  7. Distinguish between homologous and analogous structures
  8. Distinguish between monophyletic and polyphyletic group, and explain what it is meant by a natural taxonomy.

Ch. 26 Early Earth and the Origin of Life

  1. Provide at least two lines of evidence for the antiquity of life.
  2. Describe the contributions that A.I. Oparin, J.B.S. Haldane, Stanley Miller and Harold Urey made towards developing a model for abiotic synthesis of organic molecules.
  3. Provide plausible evidence to support the hypothesis that chemical evolution resulting in life’s origin occurred in four stages:
    1. Abiotic synthesis of organic monomers.
    2. Abiotic synthesis of polymers.
    3. Formation of protobionts.
    4. Origin of genetic information.
  1. Describe the basis for Whittaker’s five-kingdom system.
  2. List and distinguish among the five kingdoms.
  3. Give examples of representatives from each kingdom.

Ch. 27 Prokaryotes and the Origins of Metabolic Diversity

  1. List unique characteristics that distinguish the archae from the eubacteria
  2. Describe the three-domain system of classification and explain how it differs from previous systems.
  3. Distinguish between autotrophs and heterotrophs.
  4. List the mechanisms that are sources of genetic variation in prokaryotes and indicate which one is the major source.
  5. List the major groups of eubacteria; describe their mode of nutrition, some characteristic features and representative examples.
  6. Explain why all life on earth depends upon the metabolic diversity of prokaryotes.
