Read each question carefully and answer to the best of your ability. Refer to the cladogram provided for specific questions. This worksheet will test your understanding of cladogram analysis and evolutionary relationships.
1. What does a node on a cladogram represent?
A shared derived character
A common ancestor
An evolutionary dead end
A new species
2. Which of the following is NOT a characteristic used to construct a cladogram?
Morphological features
Genetic sequences
Behavioral patterns
Geographic location
Use the cladogram below to answer the following questions.
3. In the provided cladogram, the most recent common ancestor of all the species shown is located at the .
4. The branches on a cladogram represent over time.
5. Organisms that share a more recent common ancestor are considered more closely related.
True
False
6. A cladogram always shows the exact amount of time that has passed between evolutionary events.
True
False
7. Define the term 'shared derived character' and provide an example that could be used in a cladogram.
8. Explain the difference between an ancestral character and a derived character.
