Homologous organs are `:`

Options

A. Same origin but different functions
B. Different origin but same functions.
C. Same origin and same functions.
D. Different origin and different functions.

Answer

**Step-by-Step Solution:**

1. **Understanding Homologous Organs**:
- Homologous organs are defined as organs that have a similar origin or ancestry but perform different functions in different species.

2. **Identifying the Characteristics**:
- These organs arise from a common ancestor, meaning they share a similar structural framework.
- Despite their common origin, they have adapted to serve different purposes in various organisms.

3. **Examples of Homologous Organs**:
- A classic example is the forelimbs of mammals, such as the human arm and the wings of a bat. Both have the same underlying skeletal structure but are adapted for different functions (manipulation vs. flying).

4. **Analyzing the Options**:
- The question provides four options regarding the nature of homologous organs:
- A) Same origin but different functions
- B) Different origin but same functions
- C) Same origin and same functions
- D) Different origin and different functions

5. **Selecting the Correct Option**:
- Based on the definition and examples discussed, the correct answer is:
- **A) Same origin but different functions**. This aligns with the characteristics of homologous organs.

6. **Conclusion**:
- Homologous organs illustrate the concept of divergent evolution, where species evolve different traits from a common ancestor based on their ecological needs.
