Ch 10 Quiz - Principals of Evolution
5 points each
Part I. Read carefully and follow the directions below.
There is a population of bacteria causing an infection in your ear. The doctor
gives you an antibiotic which will kill the bacteria. There is one bacterium in the
population which is resistant (not killed) by the antibiotic.
a. Storyboard what will happen to the population over time.
Use squares to represent antibiotic-resistant bacteria.
Use circles to represent normal bacteria.

b. Explain how the population of bacteria is evolving by natural
selection.
c. What is the environmental factor (selective pressure) that is acting
on the bacteria?

Part II. DIRECTIONS: There are 4 main principles to the theory of natural
selection. Write the correct PRINCIPLE in the space next to its DEFINITION. Not
all terms will be used.
Wordbank: Adaptation, Mutation, Descent with modification,
Overproduction, Speciation, Variation.
PRINCIPLE
DEFINITION
Variation that enables certain
individuals to better survive and
reproduce more offspring with that
beneficial trait.
More offspring are produced than can
survive. Increases interspecific
competition.
Heritable differences in a population;
the more, the better.
Beneficial traits become more common
in subsequent populations; subtle
changes occur in the population over
time.
Part III. DIRECTIONS: Identify each scenario as an example of either
ARTIFICIAL SELECTION (A) or NATURAL SELECTION (N). Write A or N in the
Selection Type column.
SELECTION TYPE: A or N
SCENARIO
Jaguars with larger jaws eat more
turtles, survive, and reproduce resulting
in a population of large-jawed jaguars.
American Beauty roses with hundreds
of petals are selected for their beauty
and grown in gardens all over the
world.
Peacocks with large, showy tail
feathers appear more fit than others
and, therefore, mate more often with
pea hens.

Part III. Darwin found evidence from a wide range of sources to support his
theory of evolution by means of natural selection. In the space below, write the
correct class of evidence next to the description. Each term will be used only
once or not at all.
Word bank: Fossil Record, Biogeography, Developmental Similarities,
Anatomical Similarities, Molecular Similarities
EVIDENCE
DESCRIPTION
1. Remains found in lower layers of sediment may be
evolutionarily older than those in layers closer to
the surface.
2. The amino acid sequence for chimpanzee
hemoglobin is identical to that of humans,
suggesting a close evolutionary relationship.
3. Embryos of very different animals such as pigs,
chickens, and humans share similar structures, like
the notochord and pharyngeal arches.
4. The human forearm has the same bone structure
but different function than the front flipper of a
whale.
5. Similar species are found on different land masses.
Ex: The North American flying squirrel is very
similar to the Australian sugar glider.
Part IV. DIRECTIONS: Classify each of the following as HOMOLOGOUS (H),
ANALOGOUS (A), or VESTIGIAL (V) structures. The letters may be used more
than once or not at all.
H, A, or V
DESCRIPTION
6. Shark tail and dolphin tail
7. Bat wing and mouse fore limb
8. Human appendix and whale pelvis
9. Bird wing and butterfly wing
10. Human arm and whale flipper
