Wings of pigeon, mosquito and bat show

Options

A. divergent
B. convergent
C. atavism
D. parallel

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks about the evolutionary relationship shown by the wings of a pigeon, mosquito, and bat.

2. **Identifying the Organisms**:
- Pigeon: A bird (Class Aves).
- Mosquito: An insect (Class Insecta).
- Bat: A mammal (Class Mammalia).

3. **Function of the Wings**: All three organisms have wings that serve the same function—flight. This adaptation is crucial for their survival and mobility.

4. **Exploring Evolutionary Concepts**:
- **Divergent Evolution**: This occurs when species from a common ancestor evolve and accumulate differences, leading to the formation of new species. This is not applicable here since the organisms are not closely related.
- **Convergent Evolution**: This is the process where organisms that are not closely related independently evolve similar traits or features. This is relevant to our question since the wings of the pigeon, mosquito, and bat are similar in function but evolved independently.
- **Atavism**: This refers to the reappearance of ancestral traits that were lost in previous generations. This does not apply here as we are not discussing traits reappearing.
- **Parallel Evolution**: This involves different species evolving similar traits while remaining closely related. This does not apply as the organisms in question are from different classes.

5. **Conclusion**: Since the wings of the pigeon, mosquito, and bat evolved independently to serve the same function of flight, they exemplify convergent evolution.

**Final Answer**: The wings of pigeon, mosquito, and bat show **convergent evolution**.
