Unit 4 LC3 Summative Day

March 7, 2023

Objective: SWBAT

●
Describe the evolutionary changes within the human population over
time in order to explain the role of natural selection in the
population.

Do Now

Create a cladogram using the following organisms: Shark, Lizard, Wolf,
Human.

Use these traits to separate the organisms: Hair, Backbone, Bipedal
(walking on two legs), lungs

Multiple Choice

Which organism is most closely related to amphibians?

• Sharks

• Ray-finned fish

• Crocodiles

• Birds

Multiple Choice

Which organism is formed from an amniotic egg?

• Sharks

• Ray-finned fish

• Amphibians

• Primates

Multiple Choice

A new organism has vertebrae and a bony skeleton, but lacks four limbs, where does it belong?

• On a branch off of the sharks line

• On a branch off of the ray-finned fish line

• On a branch off of the amphibians line

• On a branch off of the crocodiles line

Multiple Choice

At what letter should the derived character of "tail" be found?

• A

• B

• C

• D

Multiple Choice

At what letter should the derived character of "opposable thumbs" be found?

• B

• C

• D

• E

Multiple Choice

Which species are more closely related, the lizard and salamander, or the lizard and hamster?

• The lizard and salamander

• The lizard and hamster

Create a visual model, using multiple types of evidence for evolution, to demonstrate the
relatedness between humans and several organisms.

●Arrange organisms to indicate which organisms are most-closely related versus
least-closely related.

●In addition to humans, include at least five of the following organisms in your final model.

o Cattle

o Chicken

o Chimpanzee

o Dog

o Mouse

o Rat

o Rhesus monkey

o Zebrafish

Part 2 – Justify the arrangement and relatedness of
your organisms in your model. 5 points

● Describe how the provided biochemical data supports

the relatedness and arrangement of your organisms.

● Explain how the anatomical, embryological, and

additional genetic evidence you gathered justifies the
relatedness and arrangement of your organisms.

Part 3 – Evaluate which type of evidence for evolution you think
is the most effective at demonstrating evolutionary
relationships and common ancestry. 5 points

● Which type of evidence do you think is most effective to

demonstrate evolutionary relationships and common
ancestry?

● Should we use just one, several, or all of the types of

evidence to determine relatedness? Why?
