LOs: Chp1-3. Briefly explain the theory of natural selection, and clarify the two conditions that
are necessary and sufficient for natural selection to bring about evolutionary change in a
population.
9) Environments all over the world are changing as a result of global warming. Could this
influence natural selection?
A) No. The environment is always changing. Global warming is nothing new.
B) Yes. Traits that help individuals produce more offspring in warmer environments will
increase in frequency.

10) The "heat" in chili peppers is due to a molecule called capsaicin. Suppose you breed chili

milder (have less capsaicin). What process is occurring?

B) environmental change
C) natural selection
D) artificial selection
Answer: D

individuals.

12) Starting from the wild mustard Brassica oleracea, breeders have created the strains known
as Brussel sprouts, broccoli, kale, and cabbage. Which of the following statements is supported
by this observation?
A) In this species, there is enough heritable variation to create a variety of features.
B) Heritable variation is low–otherwise the wild strain would have different characteristics.
C) Natural selection has not occurred very frequently in the wild populations.
D) In this species, most of the variation present is due to differences in soil, nutrition, amount
of sunlight, or other aspects of the environment.

13) Which of the following best reflects a phylogenetic conclusion regarding chimpanzees and
baboons?

14) One aspect of Darwin's theory of natural selection is that adaptations not useful to fitness
are lost faster if they have a greater cost. With this in mind, which of the following explanation
is most likely true?
A) Our little toe is not going away in the near future.
B) The human appendix must currently serve an essential function or it would not be in
our bodies.
C) It is a mystery why we do not have tails.
D) Humans are relatively hairless because we look better without
hair. Answer: A
