The wings of a bird and the wings of an insect are

Options

A. Phylogenetic structures and represent divergent evolution
B. Homologous structures and represent convergent evolution
C. Homologous structures and represent divergent evolution
D. Analogous structures and represent convergent evolution

Answer

**Step-by-Step Solution:**

1. **Identify the Structures**: The question asks about the wings of a bird and the wings of an insect.

2. **Understand the Concept of Analogous Structures**: Analogous structures are those that have different evolutionary origins but serve similar functions. In this case, both bird wings and insect wings allow for flight.

3. **Compare the Structures**: Although both wings enable flying, their anatomical structures are different. Bird wings are made of feathers and bones, while insect wings are typically made of chitin and are membranous.

4. **Functionality**: Despite the differences in structure, the primary function of both wings is the same: to facilitate flight.

5. **Convergent Evolution**: The similarity in function despite the different structures indicates that these wings evolved independently in birds and insects, a concept known as convergent evolution.

6. **Conclusion**: Therefore, the wings of a bird and the wings of an insect are analogous structures.

7. **Final Answer**: The correct option is that the wings of a bird and the wings of an insect are analogous structures.
