Worked Solution & Example Answer:The phylogenetic tree below shows the evolutionary relationship between several species of finches - VCE - SSCE Biology - Question 37 - 2023 - Paper 1
Step 1
Which pair of finches has the most recent common ancestor?
Answer
To determine which pair of finches has the most recent common ancestor, we will analyze the phylogenetic tree provided.
- Analyzing the Tree: Look closely at the branching of the tree. The branches that split most recently indicate species that are more closely related.
- Identifying Relationships: From the tree, the small ground finch and medium ground finch share a more recent common branch compared to the other options.
- Conclusion: Therefore, the correct answer is D. small ground finch and medium ground finch.
