Wings of birds and insects are

Options

A. vestigial organs
B. homologous organs
C. analogous organs
D. none of these

Answer

To answer the question regarding the wings of birds and insects, we can break down the solution into several steps:

### Step-by-Step Solution:

1. **Identify the Structures**:
- The wings of birds are modified forelimbs, while the wings of insects are made up of a different structure, including an outer and inner surface.

2. **Analyze the Origin**:
- The wings of birds originate from the forelimbs of vertebrates, while insect wings are extensions of the exoskeleton and do not share a common evolutionary origin with bird wings.

3. **Compare the Functions**:
- Both wings serve the same primary function, which is to enable flight. Despite their different structures and origins, they both allow the respective organisms to fly.

4. **Classify the Wings**:
- Since the wings of birds and insects have different structures but serve the same function, they are classified as **analogous organs**. This means they evolved independently to perform a similar function.

5. **Differentiate from Other Organ Types**:
- It is important to differentiate these from homologous organs, which have a similar structure but different functions, and vestigial organs, which are remnants of structures that had a function in ancestral species but are no longer functional.

### Conclusion:
The wings of birds and insects are analogous organs because they have different structures and origins but serve the same function of flight.
