1
The effect of natural selection in the Stickleback fish, illustrates that the advantage of traits depends upon the
principle of common descent
intensity of light
presence cytochrome c
environment
2
Following a lava flow
in the phenotype frequency of the
dark form
of the rock pocket mouse increased
False
True
3
Why did dark-colored rock pocket mice
first appear
in a population of light-colored rock pocket mice?
Individuals change color to blend in with the environment
There is dark lava rock in the area where they live
Predators eat light-colored rock pocket mice
They have genetic mutation that affects their fur color
4
Darwin
differed
from Lamarck in his proposal that
Inherent variations in the population are more important
Life on Earth did not evolve
Species are now fixed
Life on Earth has had a long evolutionary history
5
The rise of methicillin-resistant
Staphylococcus
can be considered to be an example of artificial selection because
humans purposefully attempt to make the bacteria ever-more resistant.
humans make methicillin and create environments that bacteria experience
S. aureus is cultivated by humans to replenish the soil with nutrients.
Humans are becoming resistant to bacteria by taking methicillin.
6
Natural selection as in the English peppered moth, illustrates that the advantage of inherited traits depends on the
principle of common descent
environment
presence of luck
intensity of sunlight
7
Following droughts over the years on the Galapagos Islands, the Grants observed that beak size increased
True
False
8
Natural selection is based on all of the following aspects
EXCEPT
There is differential reproductive success with populations
Variation exists within populations
Individuals with good phenotypes leave the most offspring
The tendency for the environment to create favorable traits
9
Which would be the
best technique
for determining the evolutionary relationship among several closely related species?
examining the fossil record
DNA analysis and protein comparison
comparative anatomy
comparison of homologous structures
10
Natural Selection
The process of populations becoming adapted to the environment.
The process of all things being changed over time
Becoming adjusted to different conditions
When organisms learn how to capture prey
11
All of the following influenced Darwin as he
synthesized
the concept of natural selection
EXCEPT
Malthus' "Essays on Populations"
Mendel's Laws of Inheritance
Lyell's "Principles of Geology"
The finches of the Galapagos
12
Which of the following pieces of evidence
most strongly supports
the common origin of all life on Earth?
All organisms show heritable variation.
All organisms require energy.
All organisms reproduce.
All organisms use essentially the same genetic code.
13
Which of the following best describes the mechanism behind the change in beak size in the finch population?
A new allele appearing in the finch population as a result of mutation
The achievement of dynamic equilibrium in the finch population
A change in gene freq. in the finch pop. due to selective pressure
The formation of two new finch species from a single parent species
14
Which of the following represents an idea that Darwin learned from the writings of
Thomas Malthus
?
Populations increase at a faster rate than their food supply normally allow
Earth is more than 10,000 years old
Earth changed over the years through a series of catastrophic events
The environment is responsible for natural selection
15
Biology came of age in 1859 when Charles Darwin published this book
__________
On the Origin of Species by Means of Natural Selection
Philosophie Zoologique
On the Nature of Things
Harry Potter
16
Improving through education will result in an adult's descendants being born with a greater intelligence is
Darwinism
Scala naturae
Lamarckism
Natural theology
17
The reason for the dark fur change was that
the dark phenotype was pesticide resistant
the dark phenotype was better camouflaged
the dark phenotype had a better immune system
the dark phenotype was a better runner
18
Mutations in the DNA leads to
genetic variation
False
True
19
The role that humans play in artificial selection is to
perform artificial insemination
create the genetic variants, which nature then selects.
train organisms to breed more successfully.
choose which organisms breed, and which do not.
