The homologous organs are

Options

A. Wings of pigeon and housefly
B. Wings of housefly and bat
C. Wings of pigeon and forelimbs of man
D. Wings of butterfly, bat and houselly

Answer

**Step-by-Step Solution:**

1. **Definition of Homologous Organs**: Homologous organs are those that have the same anatomical structure and origin but may serve different functions. This indicates a common evolutionary ancestor.

2. **Examples of Homologous Organs**:
- The forelimbs of mammals (like humans) and the wings of bats are homologous. Both have a similar bone structure (humerus, radius, ulna, etc.) but serve different purposes (manipulation vs. flying).
- The forelimbs of humans and the wings of pigeons are also homologous, as they share a similar bone structure despite differing functions.

3. **Distinction from Analogous Organs**: Analogous organs, on the other hand, have different anatomical structures and origins but may perform similar functions. For example, the wings of a butterfly and the wings of a housefly are analogous; they serve the same function (flying) but are structurally different.

4. **Identifying Homologous Organs**:
- Compare the anatomical structures of the organs in question. If they share a similar structure and origin, they are homologous.
- If they have different structures but perform similar functions, they are analogous.

5. **Conclusion**: In the context of the question, the homologous organs are those that share a common structural origin despite potentially having different functions. The wings of bats and the forelimbs of humans are prime examples of homologous organs.
