Which of the following does not show divergent evolution?

Options

A. Brain of bat , man and cheetah
B. Heart of bat , man and cheetah
C. Forelimbs of man , bat and cheetah
D. Eye of Octopus , bat and man

Answer

To solve the question "Which of the following does not show divergent evolution?", we need to understand the concept of divergent evolution and identify which option does not fit this definition.

### Step-by-Step Solution:

1. **Understanding Divergent Evolution**:
- Divergent evolution occurs when two or more related species become more dissimilar over time, often due to different environmental pressures or adaptations. This results in homologous structures, which are anatomically similar due to a common ancestor.

2. **Identifying Homologous Structures**:
- Homologous structures arise from divergent evolution and indicate that the organisms share a common ancestor. Examples include the forelimbs of mammals (like humans, bats, and cheetahs) which have similar bone structures but serve different functions.

3. **Analyzing the Options**:
- **Brain of Bat, Man, and Cheetah**: These are homologous structures as they share a common ancestor (vertebrates) and show divergent evolution.
- **Heart of Bat, Man, and Cheetah**: Similar to the brain, these hearts are also homologous structures from a common ancestor, indicating divergent evolution.
- **Forelimbs of Man, Bat, and Cheetah**: Again, these forelimbs are homologous structures, showing divergence from a common ancestor.
- **Eye of Octopus**: The eye of an octopus is a result of convergent evolution, not divergent evolution. Octopuses and vertebrates (like bats and humans) do not share a recent common ancestor for their eye structures, indicating that they evolved independently.

4. **Conclusion**:
- The option that does not show divergent evolution is the **Eye of Octopus**.

### Final Answer:
The correct answer is **Eye of Octopus**.
