1.

One evidence of evolution is that similar structure from related species were inherited from a common ancestor. What is the term called for this evidence?

a)

Fossils

b)

Genetic Variation

c)

Homologous Structure

d)

Natural Selection

2.

The image shows different colors of fur in giraffes. What is the environmental pressure in this example?

a)

Color of the environment

b)

Climate change

c)

Color of the prey

d)

Color of the predator

3.

The image shows different colors of fur in giraffes. Does different color of fur support or refute the theory of evolution?

a)

It supports the theory of evolution because it demonstrates genetic variation within a species.

b)

It refutes the theory of evolution because not all the species are the same fur color.

c)

It refutes the theory of evolution because giraffes can't change the color of the fur.

d)

It supports the theory of evolution because it was visible in their fossils.

4.

A penguin can hold its breathe underwater for 22 minutes. The ability to do this is an example of what term?

a)

Adaptation

b)

Natural Selection

c)

Genetic Variation

d)

Limiting Factors

5.

What is the term of factors that are living in an ecosystem?

a)

Biotic

b)

Abiotic

c)

Limiting

d)

Adaptation

6.

Five hundred Bacteria of one species were sprayed with a new antibiotics. two days later all of them died. A few, however, survived. This outcome illustrates which one of

Darwin’s key ideas about natural selection and variation?

a)

All living things come from preexisting living things

b)

Animals adapt to new environments.

c)

There is variation among individuals within a species.

d)

New species develop from survivors.

7.

The image demonstrates the evolution of horses. What is true above the theory of evolution regarding horses?

a)

The evolution of horses happened quickly.

b)

The evolution of horses happened over thousands of years.

c)

The evolution of horses happened over long periods of time.

d)

The evolution of horses did not happen.

8.

Which type of butterfly will be less likely to become extinct in the environment shown in the picture?

a)
b)
c)
d)
9.

Before the invention of the lightbulb, Americans burned oil in lamps for light. Whale oil was popular biofuel for these lamps. Ship crews would hunt whales for their oil. They searched for the largest whales they could find so that they could obtain as much whale oil as possible. How mighty decades of whale hunting possibly affect the natural selection of the species?

a)

The whales lost their legs.

b)

The whales became slower.

c)

The whales became smaller.

d)

The whales changed their calls

10.

Why do scientists study fossils?

a)

to learn how the planet was formed

b)

to study how organisms changed over time

c)

to observe how drought affected the landscape

d)

to understand how weathering affected rock layers

11.

Chameleons can change color to match the color of their surroundings. If a chameleon was born with a mutation that prevented it from being able to change color, why would it be unlikely to pass on this trait?

a)

The gene would mutate again before it was passed on

b)

The trait would be recessive, so it would not be passed on

c)

The chameleon would be unlikely to survive long enough to reproduce and pass on the trait.

d)

The chameleon would have to find another chameleon with the same trait to pass the trait on

12.

What term describes what the butterfly is doing in the picture?

a)

migrating

b)

hibernating

c)

mimicry

d)

camoflauging

13.

What is the change or ability an organism goes through to fit better with its environment?

a)

Adaptation

b)

Natural Selection

c)

Environmental pressures

d)

Fossils

14.

What are activities or factors that cause the environment to change?

a)

Adaptation

b)

Environmental Pressures

c)

Biotic Factors

d)

Fossils

15.

New species of organisms are descendants of species in the past. What does this support?

a)

Theory of Plate Tectonics

b)

Law of Superposition

c)

Theory of Evolution

d)

Law Conservation of Energy
