Preparation
Which of the following statements best describes theories?

B) They are supported by, and make sense of, many observations.
C) They cannot be tested because the described events occurred only once.
D) They are predictions of future events. - ANS B) They are supported by, and make sense of,
many observations.

(catastrophes), was Cuvier's attempt to explain the existence of
A) evolution.
B) the fossil record.
C) uniformitarianism.
D) the origin of new species.
E) natural selection. - ANS B) the fossil record.
With what other idea of his time was Cuvier's theory of catastrophism most in conflict?
A) gradualism
B) the fixity of species
C) island biogeography
D) uniformitarianism
E) the scala naturae - ANS D) uniformitarianism
What was the prevailing belief prior to the time of Lyell and Darwin?
A) Earth is a few thousand years old, and populations are unchanging.
B) Earth is a few thousand years old, and populations gradually change.
C) Earth is millions of years old, and populations rapidly change.
D) Earth is millions of years old, and populations are unchanging.
E) Earth is millions of years old, and populations gradually change. - ANS A) Earth is a few
thousand years old, and populations are unchanging.
During a study session about evolution, one of your fellow students remarks, "The giraffe
stretched its neck while reaching for higher leaves; its offspring inherited longer necks as a
result." Which statement is most likely to be helpful in correcting this student's misconception?
A) Characteristics acquired during an organism's life are generally not passed on through
genes.
B) Spontaneous mutations can result in the appearance of new traits.
, C) Only favorable adaptations have survival value.
D) Disuse of an organ may lead to its eventual disappearance.
E) If the giraffes did not have to compete with each other, longer necks would not have been
passed on to the next generation. - ANS A) Characteristics acquired during an organism's life
are generally not passed on through genes.
Which of the following is the most accurate summary of Cuvier's consideration of fossils found in
the vicinity of Paris?

B) extinction of species no; evolution of new species yes
C) extinction of species yes; evolution of new species no
D) extinction of species no; evolution of new species yes - ANS C) extinction of species yes;
evolution of new species no
In the mid-1900s, the Soviet geneticist Lysenko believed that his winter wheat plants, exposed
to ever-colder temperatures, would eventually give rise to ever more cold-tolerant winter wheat.
Lysenko's attempts in this regard were most in agreement with the ideas of
A) Cuvier.
B) Hutton.
C) Lamarck.
D) Darwin.
E) Lyell. - ANS C) Lamarck.
Charles Darwin was the first person to propose
A) that evolution occurs.
B) a mechanism for how evolution occurs.
C) that Earth is older than a few thousand years.
D) a mechanism for evolution that was supported by evidence.
E) that population growth can outpace the growth of food resources. - ANS D) a mechanism for
evolution that was supported by evidence.
Which of these conditions should completely prevent the occurrence of natural selection in a
population over time?
A) All variation between individuals is due only to environmental factors.
B) The environment is changing at a relatively slow rate.
C) The population size is large.
D) The population lives in a habitat where there are no competing species present. - ANS A) All
variation between individuals is due only to environmental factors.
Natural selection is based on all of the following except
A) genetic variation exists within populations.
B) the best-adapted individuals tend to leave the most offspring.
C) individuals who survive longer tend to leave more offspring than those who die young.
D) populations tend to produce more individuals than the environment can support.
