In the sands by desert winds
Within the Earth’s crust
In the falling rain
5. What are fossils?
A.
B.
C.
D.
Old rock formations
Layers of Earth
Organisms adapted to their surroundings
Trace remains of organisms that lived a
long time ago
6. What can comparing different
groups of animals show?
A.
B.
C.

A.
B.
C.
D.
Your hands have similar bones
You hand does similar things
Your hand has similar muscles
Your hands look the same
9. Why does your hand have almost
the same bones as a dolphin’s flipper?
A.
B.
C.
D.
Dolphins evolved from people
Dolphins and people have a common
ancestor

B.
C.
D.
All existing species have DNA

11. Which of the following factors is
necessary in order for natural selection to
occur in a species?




A
B
C
D
genetic variation within a population
an abundance of food resources
a hospitable environment
a strong family structure
12. The branching diagram shows the
relationship between several species of
finches. Which species’ DNA is most similar to
the DNA of the tree finch?




A
B
C
D
Ground finch
Cocoa finch
Vegetarian finch
Warbler finch
13. Which of the following is an example
of natural selection?




A bears moving into a new part of a forest
over many generations
B a tree growing towards sunlight
C shrubs growing longer thorns over many
generations
D a plant growing between rocks
14. Charles Darwin noticed that finches on different
islands of the Galápagos Islands were similar but that
their beaks differed. What explanation for these
differences did he propose?




A The beaks of the finches are adapted to the way
the bird usually gets food.
B Specific genetic mutations occur that make beak
size change in response to random selection factors.
C The different beaks of the finches would one day
evolve into identical beaks.
D Beak size is related to the size of the finch.
15. A scientist is studying fossils from different layers of
sedimentary rock. Which rock layer will contain fossils
that most closely resemble present-day organisms?




A
B
C
D
older rock layers
newer rock layers
all of the rock layers
none of the rock layers
16. A population of organisms is
separated into two groups for many years.
When will the two populations be
considered two different species?




A when the populations live in different
habitats
B when the populations eat different food
C when the populations behave differently
D when the populations can no longer
interbreed
17. The table shows average beak measurements for birds living

18. Which of the following is an example
of selective breeding?





become more numerous after a change in climate.
B Farmers allow only sheep that produce the best
wool to breed.
C A population of bacteria develops resistance to
an antibiotic.
D A population of insects develops resistance to a
pesticide after farmers repeatedly use the same
pesticide to kill the insects.
19. Charles Darwin’s theory of natural
selection was based partly on his
observation that




A DNA is the genetic material of all living
things.
B all eukaryotic cells have a nucleus.
C some organisms have more offspring
than others do.
