Answers
1
Which of the following is NOT part of Darwin's proposals?
there is overpopulation in nature
there is a variation in the individuals of the population
there is natural selection
the variations are caused by use/disuse
2
On the Galapagos Islands, Darwin observed
species completely unrelated to those found in South America
similar species all with traits suited to their environement
completely unrelated species on each island
species exactly like those found in South America
3
Darwin called the ability of an organisms to survive and reproduce in its environment
adaptation
fitness
diversity
evolution
4
All the genes of all members of a particular population make up the population's
relative frequency
genotype
gene pool
phenotype
5
The origin of a new species is known as
selection
fitness
survival
speciation
6
Examples of fossils include preserved
all of these
foorprints
eggs
body parts
7
What connects all of the different species in the "tree of Life"?
common ancestor
color
physical appearance
common diet
8
Which trait may increase an organism's fitness?
the ability to camouflage into their environment
having a mating call to attract predators
having fur that absorbs water in wet environments
a bird with a wide beak that eats tree insects
9
Which isolation occurs when animals cannot reproduce because of the distance between them?
reproductive structures are not compatible
geographical isolation
behavioral isolation
10
In humans the pelvis and femur is involved in walking, in whales these bones are considered
vestigial structures
fossils
acquired traits
natural variations
11
The separation of populations by barriers such as rivers, mountains, or bodies of water is
behavioral
temporal
reproductive
geographic
12
What is a factor that does NOT affect mating/reproduction?
age
timing
location
behavior
13
Which BEST describes natural selection?
natural variation is found in all populations
changes in the inherite characterisitcs of a population
unrelated but similar species live in different areas
struggle for existence by all living things
14
When lions prey on antelopes, some are killed and some survive. Darwin explained this by
acquired characterisitcs
survival of the fittest
descent with modification
reproductive isolation
15
Darwin's observation that finches of different species have similar characteristics supports
the idea that they all eat the same type of food
the theory that they all descended from a common ancestor
the theory that traits are acqired through use and disuse
the idea that they can interbreed
16
The ability of an individual to survive and reproduce in its environment.
fitness
species intelligence
species skin color
species size
17
A single species that has evolved into several different forms that live in different ways has
undergone punctuated equilibrium
has coevolved
been a victi of mass extinction
undergone adaptative radiation
18
What is adaptive radiation?
one species gives rise to many species
many variations in a population
an animal radiates to survive
species expland outward geographically
19
When a farmer breeds only his or her best livestock, the process involved is
survival of the fittest
artificial selection
natural selection
artificial variation
20
An adaptation is
the result of artificial selection
a characterisitc that can be geographical or physical
a characteristic that can be physical or behavioral
acquired during an organsim's lifetime
21
In genetic drift, allele frequencies change because of
natural selection
mutations
genetic equilibrium
chance
22
The creation of a new habitat by a small group of individuals is called
Hardy-Weinberg principal
stabilizing selection
the founder effect
directional selection
23
Darwin's theory of evolution suggests that
animals that look alike are most closely related
extinct species are not related to living species
species change over time
different species can interbreed
24
According to Darwin's theory of natural selection, individuals that tend to survive
got characterisitcs from their parent through use and disuse
have characterisitcs that breeders value
have the least humber of offspring
have variations best suited to their environment
25
Most fossils form in
sedimentary rock
sap of ancient trees
rusty water
volcanic rock
26
The fossil record shows that
fossils occur in a particular order
modern organisms have unicellular ancestors
most organisms that ever lived on Earth are now extinct
all of these
27
Which one would NOT lead to the evolution of a new species?
increased predation
geographical changes
genetic mutations
natural disaster which leads to environment changes
28
The process in which 2 species evolve in response to changes in each other over time is
coevolution
adaptive radiation
punctuated equilibrium
convergent evolution
29
Which statement about evolution in the Galapagos finches is true?
Mate choices likely plays no role in their evolution
Stabilizing selection has favored an intermediate beak type
Natural selection on beak size and shape is driven by food
None of the finch species is reproductively isolated
