Evolution Primer: Study Guide
Nothing in biology makes sense except in the light of evolution.
Theodosius Dobzhansky, 1973
A. The nature of a paradigm
B. Paradigms die hard
C. Evolutionary paradigms: old and new
Evolution - the biological
A. Evolution explains the unity and diversity of life
B. Evolution unifies biological observations into a coherent whole
III. The evolution of evolution. Some early evidence
Lamarck - a step in the right direction
Darwin - evolution by means of natural selection
A. Brief biography
1. H.M.S. Beagle
2. Lyell and uniformitarianism
3. The Galapagos - island biology
4. Reverend Malthus
C. Natural Selection
VI. Wallace - the time was ripe
VII. Gould's evidence for evolution
A. Direct observations
B. Imperfections of nature
C. Fossil record
VIII. Evolution as science
Goal of this Unit: The goal of this unit is to understand the historical development, significance and central importance of evolution. Further, well will analyze recent attacks on evolutionary theory.

J. Gould has published several excellent collections of essays concerning
evolution (i.e., The Panda's Thumb, Ever Since Darwin).
Essays that directly
pertain to class material include "The Freudian Slip", "The
Panda's Thumb". "Evolution as Fact and Theory, published in
Discover is another good one.

There are also excellent videos on evolution available in our libraries. These include:
Evolution, a co-production of the WGBH/NOVA Science Unit and Clear Blue Sky Productions. Eight volume series. Available at Clemens (QH367 .E86 2001). For more about the series click here.
God, Darwin and the Dinosaurs; A production of Cineworks, Inc. in association with WGBH Boston for NOVA. Chronicles the history of the creation-evolution controversy in the United States and examines the arguments put forth by the supporters of both views. Available in both libraries at B818 .G62 1993
Dawn of man: the story of human evolution; A BBC/The Learning Channel co-production. Available at Alcuin at GN281 .D38 2000.
Important Terms/Concepts: (Be able to use conversationally.)
Questions for Thought and Study:
Why is evolution important?
Discuss how each of the following provide evidence for evolution: comparative anatomy, embryology, geology, paleontology, breeding.
is a homologous structure? analogous
structure? vestigial organ? What
Discuss peppered moths and antibiotic resistance in microorganisms as examples of evolutionary change. Can you think of any others?
What does Darwin mean by fittest?
What is adaptation? Why is it important?
Why is it true that organisms are never perfectly adapted?
Discuss the significance of Dobzhansky's quote at the beginning of this guide.
Stephen Gould argues that the proof of evolution is revealed by the imperfections of nature. Using an example such as the Panda's thumb, explain what he means.
Evolution is a testable, falsifiable theory. Explain using an example.
Explain the fallacy expressed by ex-President Reagan's quote below. Contrast it with the quote by Darwin.
Why do males have nipples?
Explain why, from an evolutionary perspective, males/females have organisms.
There is a separation of the site of organism and the site of intercourse in human females. Explain why, from a strictly adaptationist viewpoint this separation is unexpected. Then, explain why this situation exists.
Can you define adaptation? Can you give an example?
Gould cites three major pieces of evidence in support of evolution. What are they? (hint: direct observation, imperfections, fossils).
Check out the questions at the end of the chapters.
Do you agree with Tom Robbin's description of evolution?
What is the equation for the Hardy-Weinberg equilibrium model for evolution. Can you work simple Hardy-Weinberg problems? Bring a calculator to the exam.
Identify the criteria that must be met for the Hardy-Weinberg model to be satisfied. Describe the result if one or more of these criteria are violated.
Identify five factors/mechanisms that result in evolutionary change.
Define migration, genetic drift, and mutation. What is the function and/or result of each?
Compare and contrast the Bottleneck effect and Founder effect. Give an example of each.
What the three major types of natural selection? Give examples of each. Identify the environmental conditions (ie., stable vs. changing) for each.
Can you identify each of the following individuals: Buffon, Lamarck, Wallace, Darwin, Malthus, Fitzroy, Hardy-Weinberg; Dobzhansky.
Well, it is a theory. It is a scientific theory only and it has in recent years been challenged in the world of science - that is, not believed in the scientific community to be as infallible as it once was.

Firstly, to show that species had not been specially created and
secondly that natural selection has been the chief agent of
change...Hence, if I have erred in....having exaggerated its [natural
selection's] power...I have at least, I hope, done good service aiding to
overthrow the dogma of separate creations.
