Analogous organs have a

Options

A. common embryonic origin but perform different functions
B. different embryonic origin and perform different functions
C. common embryonic origin and perform similar functions
D. different embryonic origin but perform similar functions

Answer

**Step-by-Step Solution:**

1. **Understanding Analogous Organs**:
- Analogous organs are defined as organs that perform similar functions but have different evolutionary origins. This means that they do not share a common ancestor.

2. **Characteristics of Analogous Organs**:
- They arise from different embryonic origins.
- They have different structures.
- Despite their differences in origin and structure, they perform similar functions.

3. **Example of Analogous Organs**:
- A classic example of analogous organs is the wings of birds and the wings of butterflies.
- Both serve the function of flight, but they evolved independently and have different structural features.

4. **Identifying the Correct Option**:
- The question provides four options regarding the characteristics of analogous organs:
- Option A: Common embryonic origin but perform different functions (Incorrect)
- Option B: Different embryonic origin and perform different functions (Incorrect)
- Option C: Common embryonic origin and perform similar functions (Incorrect)
- Option D: Different embryonic origins but similar functions (Correct)
- Based on the definition and characteristics of analogous organs, the correct answer is Option D.

5. **Conclusion**:
- Therefore, the correct statement regarding analogous organs is that they have different embryonic origins but perform similar functions.
