Homologous organs have

Options

A. Similar morphology
B. Similar anatomy
C. Different anatomy
D. All of the above

Answer

**Step-by-Step Text Solution:**

1. **Understanding Homologous Organs**: Homologous organs are those that have a similar structure but may serve different functions in different organisms. They arise from a common ancestor and have similar developmental origins.

2. **Identifying Characteristics**: The key characteristics of homologous organs include:
- Similar morphology (structure)
- Different functions
- Same developmental origin

3. **Examples of Homologous Organs**: A classic example is the forelimbs of mammals (like humans, whales, and bats). Although they serve different functions (grasping, swimming, flying), they share a similar bone structure, indicating their common ancestry.

4. **Options Analysis**: The question provides several options:
- Similar morphology
- Similar or not be
- Different or not be
- All the above

5. **Correct Answer**: Based on the definition and characteristics of homologous organs, the correct answer is "similar morphology." This is because homologous organs are defined by their structural similarities, despite their different functions.

6. **Conclusion**: Therefore, the statement "Homologous organs have similar morphology" is accurate.
