Study Guide for Chapter 6 Test
Test date: Wednesday, February 20
Read over your quizzes and homework. These are the two main sources for test material with, naturally,
your notes coming in very handy. Go back and look over the criteria you would be responsible for as
stated in my weekly lesson plans. If you can answer the essential questions for each day, then you are
already ahead of the game. You should have a good understanding of genetics and heredity by now and
be able to make connections between these ideas and evolutionary theory.
You will be responsible for all terms from chapters 6 INCLUDING terms from notes not found in your
book.
1. Darwin’s Theory:
a. Know the important dates mentioned in the book for Charles Darwin: 1831 (voyage
begin on the HMS Beagle), 1839 (publication of The Voyage of the Beagle), 1859
(Publication of The Origin of Species)
b. What is a scientific theory?
c. Understand the difference between artificial and natural selection.
d. What is the important criterion making a species a species? (_________ offspring)
e. What is the gradual change over time called? How did Charles Darwin refer to this?
f. Name the islands Darwin visited and locate them on a map.
g. What is an “archipelago?”
h. Know the four main points of Darwin’s theory of natural selection.
i. How does the ever changing environment affect natural selection?
2. Evidence for Evolution:
a. Understand four types of evidence that supports evolution.
b. What are homologous structures? Be able to compare some examples.
c. What are vestigial structures? Be prepared to gives some examples: appendix, tails on
humans, pelvic girdle (hips) on snakes etc.
d. What does “Ontogeny Recapitulates Phylogeny” mean? Is it an accurate theory?
e. How does the fossil record help scientists understand the theory of evolution?
f. What does the term “early development” refer to?
3. Rate of Change:
a. Be able to explain how a new species forms.
b. Identify two patterns that describe the rate of evolution.
c. Understand how isolation can affect a species and the differences between natural and
artificial barriers.
d. Identify the differences between gradualism and punctuated equilibrium?
e. Could either one or both of the above be correct?
f. What does the term “intermediate form” refer to?
g. Why are fossils of intermediate life forms likely to be rare if the pattern of punctuated
equilibrium explains how evolution occurs?
4. As per usual, expect to be asked about the Cell Theory and Photosynthesis (the most important
equation to life as we know it).
