The wings of pigeon, butterfly and bat show

Options

A. Divergent evolution
B. Atavism
C. Convergent evolution
D. All of these

Answer

To solve the question regarding the wings of pigeon, butterfly, and bat, we need to analyze the types of evolution and how these wings relate to them.

### Step-by-Step Solution:

1. **Understanding the Types of Evolution**:
- **Divergent Evolution**: This occurs when two or more related species become more dissimilar over time, often because they adapt to different environments. They share a common ancestor but develop different traits.
- **Convergent Evolution**: This occurs when unrelated species develop similar traits or adaptations due to similar environmental pressures, despite having different ancestral origins.

2. **Identifying the Organisms**:
- The wings of a pigeon (a bird), a butterfly (an insect), and a bat (a mammal) are the focus of the question. These three organisms belong to different classes and phyla:
- Pigeon: Class Aves
- Butterfly: Class Insecta
- Bat: Class Mammalia

3. **Analyzing the Wings**:
- Although the wings of these three organisms serve the same function (flight), they have evolved independently from different ancestral lines.
- The structure of the wings differs significantly among these organisms:
- Pigeon wings are made of feathers and are adapted for powered flight.
- Butterfly wings are made of scales and are also adapted for flight but are structurally different from bird wings.
- Bat wings are formed from a membrane stretched between elongated fingers, which is distinct from both the pigeon and butterfly wings.

4. **Conclusion**:
- Since the wings of pigeon, butterfly, and bat have evolved to perform the same function (flying) but do so from different evolutionary backgrounds, this is an example of **convergent evolution**.

5. **Final Answer**:
- Therefore, the correct answer to the question is **C. Convergent evolution**.
