1. Which of the following sources of data can be used to study evolution?
A. Frequencies of traits in populations.
B. Morphological data from fossil organisms.
C. DNA sequence data.
D. All of the above.: D.
2. Which statement characterizes good scientific theories?A.They should be able
to withstand challenges from conflicting evidence.
B. They should eliminate the need to test every prediction.
C. They should rely on widely accepted assumptions.
D. They should organize facts and lead to testable predictions.: D.
3. A lineage, in an evolutionary sense, is best described how?
A. A successive chain of ancestor and descendent populations perpetuating
through generations.
B. Species evolving into other species.
C. A collection of unrelated species that interact.
D. An ancestral species and some of its descendents.: A.
4. Linneaus's classification system functions well for living organisms. A lit-
tle-known fact is that he attempted to apply the same system to rocks and
minerals. This has fallen out of use. Why might this be the case?
A. Rocks and minerals do not naturally have Kingdoms, Phyla, and so on.
B. The concept of "species" requires that organisms reproduce sexually.
C. The fact that rocks and minerals do not evolve means there is no evident
hierarchy of relatedness.
D. Plants and animals are more complex (higher) than rocks and minerals on
the great chain of being, therefore it is easier to understand how they should
be classified.: C.
5. Thomas Malthus' use of mathematical description of the changes in human
population size explained _________.
A. the laws of heredity.
B. the reason plants and animals regulate their population sizes to sustainable
levels.
C. the reason that sufficient mutations could occur to sustain evolutionary

E. a, b, and c are all correct: D.
7. Modern day mammals are descended most recently from what group:
A. synapsids
B. reptiles
C. fish
D. amphibians: A.
8. Lord Kelvin argued that based on the temperature of rocks, the earth could
not be as old some geologists thought. What turned out to be wrong with his
reasoning?
A. he claimed that the temperature of surface rocks should be used in calcula-
tions, but these calculations were shown to be unreliable
B. he did not realize that the planet's interior was constantly changing
C. the upper layers of the earth are cooler than Kelvin realized
D. all of the above: B.
9. The earliest generally accepted fossils of living organisms are:
A. yeasts
B. stromatolites
C. zircons
D. carbon isotopes: B.
10. The transition of from single-celled to multi-celled organisms:
A. happened once
B. happened on multiple occasions
C. occurred before the origin of eukaryotes
D. a and c are correct
E. b and c are correct: B.
