Evolution Review Packet
Name
Directions: In this packet, various activities and lessons will be addressed. Answer each question as thoroughly as possible as this will
serve as your review guide for the test on Evolution. Use diagrams when necessary to further explain an idea.

2.
Biological evolution is the consequence of four factors interacting within a population of living organisms. Underline these
four factors in the table above.
3.
Is it possible to change to better suit a new environment in one’s lifetime and pass on those new adaptations to offspring?
Circle: YES or NO
Explain why or why not.
Give one example to show you understand your reason above.
4.
Based off of the Musical Chairs Natural Selection activity, address the following tasks or questions.
3 stamps
a.
Describe the environment in which the lemurs lived. What was “nature” like?
b.
How exactly did “nature” select for traits?
c.
What was the most successful mutation for this particular environment?
Why was it the most successful trait?
d.
Consider the following scenario and respond accordingly: The Floornchairs continent tectonically moved to an area
of hot, extremely arid conditions where the new food source was small extensions of really tall trees. Predict what
the population of lemurs would look like in 1000 years and explain why the population would change that way.

Based on the Peppered Moth Story, answer the following questions:
a.
Describe the change in population from 1850 to 1900.
b.
Describe the environmental change that took place during the industrial revolution.
c.
Which moths were better adapted for their environment in 1850? Which ones in 1900?
d.
Did the moths spontaneously change from light to dark and vice versa? Why or why not?
e.
How do antibiotics and pesticides create resistant bacteria and insects?
f.
Do you think the evolution of the organisms in musical chairs or peppered moth will ever stop? Explain why or why
not.
Based on the Rock Pocket Mouse Story, answer the following questions:
a.
Describe the change in population over time.
b.
Describe the environmental change that took place after the volcanic eruption.
c.
Which mice were better adapted for their environment before the volcanic eruption? After?
d.
Did the mice spontaneously change from light to dark and vice versa? Why or why not?

After completing the Caminalcules activity, answer the following questions:
a.
Think about a Caminalcule lineage that remained unchanged for millions of years. Based off of the Caminalcule
fossil record, what do you infer caused or allowed this to occur?
b.
Explain how a common ancestor diverged into 2 different species.
c.
Compare your Caminalcule tree with a neighboring group. Is their fossil record mostly similar or mostly different
than your’s? Consider and list 2-3 possible difficulties scientists may encounter when setting up the fossil record
and explain why they would be difficult.
d.
Identify any examples of convergent evolution and circle them on your poster. Why do you think this occurred?
e.
Find a section of your Caminalcule phylogenetic tree that shows 4-5 fossils and re-draw that image below.
i.
Circle the two organisms that represent the most closely related.
ii.
Square the two organisms that represent the most distantly related.

8.
Explain how natural selection accounts for the world’s diversity. Use all the following words in your response and underline
them when used: Population, species, variation, mutation, time, nature/earth, individuals, survive.
9.
Answer the fundamental question of Natural Selection: How does natural selection affect individuals but act on
populations? Use an example in your response that shows how one organism was affected by “nature” and how their
population was affected.
10. Explain why natural selection does not move in a pre-determined direction.
11. Describe how Darwin’s Theory of Evolution accounts for all diversity on earth.
