Analogous organs are:

Options

A. Similar in origin
B. Similar in structure
C. Non-functional
D. Similar in function

Answer

**Step-by-Step Solution:**

1. **Understanding Analogous Organs**: Analogous organs are structures in different species that perform similar functions but do not share a common evolutionary origin. This means that while they may look or function similarly, they evolved independently.

2. **Analyzing the Options**:
- **Option A: Similar in origin**: This is incorrect because analogous organs have different origins.
- **Option B: Structure is same**: This is also incorrect. While they may serve similar functions, their structures may differ due to different evolutionary paths.
- **Option C: Non-functional**: This is incorrect as well. Analogous organs are functional; they serve specific purposes in the organisms that possess them.
- **Option D: Their function is same**: This is correct. Analogous organs perform similar functions, even though they arise from different evolutionary backgrounds.

3. **Conclusion**: Based on the analysis of the options, the correct answer is that analogous organs are those that have the same function but different origins.

**Final Answer**: D. Their function is the same.
