Review
2
Multiple Choice
These structures are examples of __________ structures.
3
Homologous Structures
Have the same structure but different function.
4
Multiple Choice
These structures are examples of __________ structures.
5
Analogous Structures
Have the different structure but same function.
6
Multiple Choice
These structures are examples of __________ structures.
7
Vestigial Structures
Are remnants (remaining parts) that were important in the organism’s ancestors, but are no longer used in the same way.
8
Multiple Select
The image shows an example of _________ evolution.
9
Divergent Evolution
The process where groups from a COMMON ancestor evolve and accumulate DIFFERENCES, resulting in the formation of new species.
10
Multiple Select
The image shows an example of _________ evolution.
11
Convergent Evolution
The process where organisms NOT CLOSELY related, independently evolve SIMILAR traits as a result of having to adapt to similar environments.
12
Multiple Choice
According to the model, which of the following are humans more CLOSELY related?
13
Phylogenetic Tree
You can see in the model that the Human is more closely related to the Chimp, versus being less closely related to the Orangutan.
14
Multiple Choice
According to the model, which of the following is NOT a descendant of the organism identified (red circle).
15
Phylogenetic Tree
The Humans, Chimps, and Bonobos are all descendants of the organism marked with the red circle. The Gorillas and Orangutans are NOT.

Type answer...
17
Phylogenetic Tree
You can see that the dog diverges at 65 MYA to its own line, different from the pig, cattle, and horse.
18
Multiple Choice
According to the Model, which two organisms are most closely related?
19
Amino Acid Sequencing
B and C have zero differences in amino acids, so they are most closely related.
20
Fill in the Blanks
Type answer...
21
Amino Acid Sequencing
B and C have zero differences in their Amino Acid sequencing so they are MORE closely related.
22
Open Ended
Using the model of amino acid sequencing, make a claim stating which organisms are the least closely related.
23
Claim
Your claim might read like this "Organism E and F are the least closely related".
24
Open Ended
Using the model of amino acid sequencing, Provide one piece of evidence supporting the claim that "Organism E and F are the least closely related".
25
Evidence
Your evidence might read like this "Organism E and F have 9 differences in their amino acid sequencing, which is the most in the table, supporting that they are the least closely related".
