1. Variation within species was important to the development of Darwin’s theory of evolution. Which
statement does individual variation help explain?
A. Resources become limited over long periods of time.
B. Populations often increase rapidly and without warning.
C. Competition is fierce among members of different species.
D. Some organisms survive and reproduce better than others.
The ears of foxes help to regulate body heat. The fennec fox lives in the North African desert and has
large ears that release body heat. The Arctic fox lives in cold climates and has small ears that conserve
body heat.
2. Which of these processes led to the development of different ear sizes in foxes?
A.
B.
C.
D.
selective breeding
succession
natural selection
mutualism
3. Which of these best illustrates natural selection?
A.
B.
C.
D.
An organism with favorable genetic variations will tend to survive and breed successfully.
A population monopolizes all of the resources in its habitat, forcing other species to migrate.
A community whose members work together utilizes all existing resources and migratory routes.
The largest organisms in a species receive the only breeding opportunities.
4. A small portion of the population that is geographically isolated from the rest of the population runs
the risk of decreased
A.
B.
C.
D.
genetic drift
mutation rate
natural selection
genetic variation

5. Which of these processes would most likely cause new color patterns on the head and neck of bog
turtles?
