Instructions: Answer all questions to get your test result.
1) Which of the following can occur when a population is geographically isolated from another population?
A
replication
B
mimicry
C
convergence
D
speciation
2) A change in structure, behavior, or physiology that enhances survival and reproductive success in a particular environment is called
A
genetic drift
B
gene flow
C
adaptation
D
mimicry
3) The genetic change in populations that gives rise to new life forms from common ancestors is :
A
genetic drift
B
natural selection
C
gene flow
D
evolution
4) What is the best explanation for similar bone structures seen in vertebrates?
A
survival of the fittest
B
fossils
C
gene flow
D
common ancestors
5) When is evolution most likely to occur?
A
when there is shelter for all animals
B
when there is plenty of food
C
when there are no predators
D
when there is a competition for resources
6) What explains genetic variations in mice living in 2 different areas?
A
Mutation and sexual recombination both created new variations in body size
B
They needed to adapt to survive, so favorable traits developed
C
They were injured during their lifetime, so these new traits were handed down to the offspring
D
They wanted to be different, so traits appeared
7) What does a paleontologist study?
A
fossils
B
Human genetics
C
biochemistry
D
Animal behavior
8) This term refers to how species vary at the ecosystem, species, and genetic levels.
A
biodiversity
B
natural selection
C
convergence
D
genetic flow
9) Over long periods of time, some taxa have become extinct, while new taxa have evolved. This refers to:
A
artificial selection
B
microevolution
C
macroevolution
D
adaptation
10) Geologic time periods are determined by:
A
an equal number of years
B
the activity of rock layers
C
the depth of sediments in rock layers
D
the origin and extinction of taxa
11) Finches are closely related species of birds. Over time, beaks evolved for each location of birds based on food availability. This is an example of:
A
coevolution
B
sexual selection
C
gene flow
D
adaptive radiation
12) These are the longest remaining taxa on Earth.
A
multi-cellular organisms
B
single-celled organisms
C
birds
D

13) A man loses is arm in an auto accident. He is worried that his children will be born with missing arms as well. The problem is:
A
acquired characteristics during lifetime cannot be passed to offspring
B
only some of the offspring will be born with missing arms
C
the offspring could have a need for 1 arm and therefore be passed on
D
the offspring are less likely to survive
14) White moths are easily seen in a black forest, so predators eat them. The black moths survive because:
A
they need to be black in order to reproduce
B
they fight predators off better
C
they are more fit because of their black coloring
D
they fly faster

A
natural selection
B
variation
C
evidence
D
mutation
16) Gorillas compete to become the dominant male in their group. Unsuccessful males are less likely to mate than successful ones. This is an example of:
A
adaptive radiation
B
gene flow
C
homology
D
sexual selection
