Question
### Phylogenetic Tree Relationships Use the following information to answer the question. ![Phylogenetic Tree](add-link-to-image-if-present) The diagram above represents the evolutionary relationships among seven species (A, B, C, D, E, F, G) as depicted in a phylogenetic tree. **Question:** Which of the following trees, if any, depicts the same relationship among species as shown above? Below are three alternative phylogenetic trees: 1. **Tree 1:** ``` A B C D E F G \ | / \ / \ | / \ / Y Z \ / W__________/ ``` - Description: This tree is structurally identical to the original tree with species A, B, and C branching from one point, and species D, E, F, and G branching from another point further along the tree. 2. **Tree 2:** ``` G F E D C B A \ | / \ / \ | / \ / Y Z \ / W__________/ ``` - Description: In this tree, the species are rearranged such that G, F, and E branch from one point, and D, C, B, and A branch from another point further along the tree. 3. **Tree 3:** ``` G F E D C B A \ | / \ / \ | / \ / Y Z \ / W__________/ ``` - Description: This tree is identical to Tree 2 in structure but appears here again for verification and consistency. **Analysis:** - Carefully examine each phylogenetic tree to determine if the branching patterns and evolutionary relationships depicted are identical to the original tree. Pay close attention to the order and points of divergence. This exercise helps in understanding how to read and compare phylogenetic trees to determine the evolutionary relationships among different species.
