**Question:**
Based on this phylogenetic tree, which organisms are the most distantly related?
**Phylogenetic Tree Diagram Explanation:**
The phylogenetic tree illustrates the evolutionary relationships among various whale species, displaying their common ancestry. The branches indicate how closely or distantly related different species are based on their evolutionary history. The tree starts with:
1. **B. bonarensis** (Southern Minke Whale)
2. **B. acutorostrata** (Northern Minke Whale)
3. **B. physalus** (Fin Whale)
4. **B. edeni** (Pygmy Bryde's Whale)
5. **B. borealis** (Sea Whale) - highlighted in red
6. **B. brydei** (Bryde's Whale)
7. **B. musculus** (Blue Whale)
8. **Megaptera novaeangliae** (Humpback Whale)
9. **Eschrichtius robustus** (Gray Whale)
The branching indicates that the Southern and Northern Minke Whales are closely related, while the Gray Whale is the most distantly related to the others on this tree.
**Answer Choices:**
- ○ **B. musculus** (Blue Whale) and **B. physalus** (Fin Whale)
- ○ **B. acutorostrata** (Northern Minke Whale) and **B. edeni** (Pygmy Bryde's Whale)
- ○ **B. brydei** (Bryde's Whale) and **B. edeni** (Pygmy Bryde's Whale)
- ○ **Megaptera novaeangliae** (Humpback Whale) and **Eschrichtius robustus** (Gray Whale)
The correct answer choice should identify the two species with the greatest evolutionary distance according to the tree shown.
Expert Solution
Step 1
Evolution is a continuous process and we are still evolving. Evolution is nothing but adapting to the circumstances and passing their traits to the offspring’s for development.
Phylogeny is the study which decreases the evolutionary relationships between the organisms and the evolutionary development of those organisms. Phylogenic tree gives the pictorial representation and makes easy to understand that relationship.
The evolutionary history of a species is called as a phylogeny of that species.
