Read each question carefully and answer to the best of your ability. Refer to the provided phylogenetic tree diagram for relevant questions.
Observe the hypothetical phylogenetic tree below:
1. Which of the following best describes a phylogenetic tree?
A diagram showing the geographical distribution of species.
A branching diagram showing evolutionary relationships among biological species.
A chart detailing the genetic makeup of a single organism.
A linear timeline of Earth's geological history.
2. In the phylogenetic tree provided, which two species are most closely related?
Species A and Species C
Species B and Species E
Species D and Species E
Species A and Species B
3. The point where two branches diverge on a phylogenetic tree represents a , indicating a common ancestor.
4. Organisms that share a more recent common ancestor are considered more related.
5. Explain the significance of the "root" of a phylogenetic tree.
6. Describe one type of evidence scientists use to construct phylogenetic trees.
