Answers
1

comparative embryology
homologous structure
analogous structures
comparative biochemistry
2
In birds, if one group has short beaks and one group has long beaks what process has occurred?
directional
stabilizing
temporal
disruptive
3
Which of the following about genetic drift is FALSE?
smaller populations will show a large impact
individual from one population breed with another population
happens by chance
gene pool changes
4
What connects all of the different species in the "tree of Life"?
common diet
color
common ancestor
physical appearance
5
When lions prey on antelopes, some are killed and some survive. Darwin explained this by
survival of the fittest
reproductive isolation
descent with modification
acquired characterisitcs
6
Which trait may increase an organism's fitness?
a bird with a wide beak that eats tree insects
having fur that absorbs water in wet environments
the ability to camouflage into their environment
having a mating call to attract predators
7
Darwin's observation that finches of different species have similar characteristics supports
the idea that they can interbreed
the idea that they all eat the same type of food
the theory that traits are acqired through use and disuse
the theory that they all descended from a common ancestor
8
Which one would NOT lead to the evolution of a new species?
genetic mutations
geographical changes
natural disaster which leads to environment changes
increased pradation
9
Darwin's theory of evolution explains all of the following EXCEPT
how species change over time
how inherited traits are passed from parent to child
how evolution takes place in the natural world
how species became extinct
10
The ability of an individual to survive and reproduce in its environment.
species size
fitness
species intelligence
species skin color
11
Which BEST describes natural selection?
changes in the inherite characterisitcs of a population
natural variation is found in all populations
struggle for existence by all living things
unrelated but similar species live in different areas
12
The creation of a new habitat by a small group of individuals is called
stabilizing selection
the founder effect
Hardy-Weinberg principal
directional selection
13
Most fossils form in
sap of ancient trees
volcanic rock
sedimentary rock
rusty water
14
According to Darwin's theory of natural selection, individuals that tend to survive
have variations best suited to their environment
got characterisitcs from their parent through use and disuse
have the least humber of offspring
have characterisitcs that breeders value
15
Darwin called the ability of an organisms to survive and reproduce in its environment
fitness
diversity
adaptation
evolution
16
Whose theory of evolution was eventually proved to be incorrect?
Darwin
Mendel
Wallace
Lamarck
17
The origin of a new species is known as
survival
selection
fitness
speciation
18
Mass extinctions encourage the rapid evolution of surviving species
because they killed all organisms that coevolved
because they spared all organisms that evolved convergently
by changing developmental genes
by making new habitats available
19
In humans the pelvis and femur is involved in walking, in whales these bones are considered
natural variations
vestigial structures
fossils
acquired traits
20
A single species that has evolved into several different forms that live in different ways has
undergone punctuated equilibrium
has coevolved
undergone adaptative radiation
been a victi of mass extinction
21
What is adaptive radiation?
species expland outward geographically
one species givves rise to many species
many variations in a population
an animal radiates to survive
22
The Galapagos finch species are an excellent example of
selection on single-gene traits
speciation
stabilizing selection
genetic equilibrium
23
The separation of populations by barriers such as rivers, mountains, or bodies of water is
behavioral
geographic
reproductive
temporal
24
The fossil record shows that
all of these
modern organisms have unicellular ancestors
fossils occur in a particular order
most organisms that ever lived on Earth are now extinct
25
An adaptation is
a characterisitc that can be geographical or physical
the result of artificial selection
a characteristic that can be physical or behavioral
acquired during an organsim's lifetime
26
After Precambrian time, the basic divisions of the geologic time scale from larger to smaller
relative and absolute dates
billions of years and millions of years
eras and periods
periods and eras
27
To compare the relative ages of fossils, scientists sometimes use an easily recognized species
radioactive fossil
carbon fossil
index fossil
sedimentary fossil
28
Fossilized evidence of Earth's first forms of life would consist of
vertebrates from the Precambrian
Eukaryotes from the Precambrian
Prokaryotes from the Precambrian
Invertebrates from the Precambrian
29
On the Galapagos Islands, Darwin observed
species completely unrelated to those found in South America
similar species all with traits suited to their environement
species exactly like those found in South America
completely unrelated species on each island
30
Which isolation occurs when animals cannot reproduce because of the distance between them?
behavioral isolation
geographical isolation
reproductive structures are not compatible
31
The situation in which allele frequencies of a population remain constant
evolution
genetic drift
natural selection
genetic equilibrium
32
Lamarck's thoery of evolution includes the concept that new organs appear due to
the actions of organisms as they use or not use body parts
natural variations are already present in the population
continual increase in population size
an unchaging local environment
33
Which of the following is NOT part of Darwin's proposals?
the variations are caused by mutations
there is a variation in the individuals of the population
there is overpopulation in nature
there is natural selection
34
In genetic drift, allele frequencies change because of
mutations
natural selection
chance
genetic equilibrium
35
Genetic drift tends to occur in populations that
have unchanging allele frequencies
are small
are formed from a new species
are very large
36
All the genes of all members of a particular population make up the population's
relative frequency
gene pool
phenotype
genotype
37
When a farmer breeds only his or her best livestock, the process involved is
artificial variation
natural selection
artificial selection
survival of the fittest
38
What was the name of the ship Darwin sailed on?
MHS Labrador
HMS Beagle
MHS Beagle
HMS Labrador
39
Which statement about evolution in the Galapagos finches is true?
Natural selection on beak size and shape is driven by food
Mate choices likely plays no role in their evolution
None of the finch species is reproductively isolated
Stabilizing selection has favored an intermediate beak type
40
Examples of fossils include preserved
body parts
foorprints
eggs
all of these
41
What is a factor that does NOT affect mating/reproduction?
location
timing
behavior
age
42
What differences are apparent in the heads of the bird species shown in the picture?
color
wing length
beak size
eye shape
43
Darwin's theory of evolution suggests that
extinct species are not related to living species
different species can interbreed
animals that look alike are most closely related
species change over time
44
The process in which 2 species evolve in response to changes in each other over time is
convergent evolution
adaptive radiation
coevolution
punctuated equilibrium
