Test Description: Evolution Test Review 2
Instructions: Answer all questions to get your test result.
1) Which of the following best supports the theory of evolution through natural selection?
A
Dogs that win dog show awards have usually been selectively bred for that purpose.
B
Traits improving an organism's ability to survive/reproduce are passed to the next gen of species.
C
Species that share the same habitat and food resources tend to compete for those resources.
D
When temps are high in summer or low in winter, some plants will experience a period of dormancy.
2) Which of the following provides the best evidence that two different species evolved from a common ancestor?
A
They occupy the same niche.
B
They live the same length of time.
C
They both undergo metamorphosis.
D
They share similar physical traits.
3) Which of the following provides the best evidence that two different species evolved from a common ancestor?
A
They have both been around for a long time.
B
They are adapted to the same conditions.
C
They share much of the same DNA.
D
They eat the same kinds of foods.
4) If a major environmental change were to occur, in which type of ecosystem would some organisms be most likely to survive?
A
an ecosystem that is geographically isolated
B
an ecosystem in which there is a limited carrying capacity
C
an ecosystem with lots of biodiversity
D
an ecosystem relying on only a few producers
5) According to the theory of natural selection, what will most likely happen to a species that possesses a trait unfavorable to an environment?
A
The species will migrate to an area in which its unfavorable trait becomes favorable.
B
The species will not produce many offspring that survive and reproduce.
C
The species will become extinct when environmental conditions change.
D
The species will spread the genes for the trait throughout the population.
6) Which statement best explains how phenotypic variation affects the survival of a species?
A
It increases odds that some individuals w/in a species will survive changes in environ.
B
It causes individuals w/in a species to spread out to different environ so speciation will occur.
C
It allows a species to shape its environment in ways that make it more inhabitable.
D
It helps protect a species against genetic diseases that spread more easily with inbreeding.
7) If a species' environment undergoes a drastic change, what will most likely help the species survive the change?
A
asexual reproduction
B
mutations
C
disease resistance
D
homeostasis
8) The process by which a population becomes better suited to its environment is known as
A
adaptation.
B
accommodation.
C
variation.
D
selection.
9) The finches that Darwin studied differed in the shape of their beaks. According to Darwin, the finches probably
A
had been created by design that way.
B
ate the same diet.
C
were descended from birds in Africa.
D
all had a common ancestor.
10) A large section of rainforest was cut down to clear space for crops. The section of rainforest was home to a rare bird species, & was the birds' only known habitat. The result
A
would be that the birds will evolve into a new species.
B
would be that the birds will eventually go extinct.
C
would be that the birds will adapt to eating soybeans.
D
would be that the birds will migrate to a new habitat.
