The divergent evolution can be seen in

Options

A. Analogous structures
B. Artificial breeding
C. Drug resistance
D. Homologous structures.

Answer

**Step-by-Step Solution:**

1. **Understanding Divergent Evolution**: Divergent evolution occurs when two or more related species become more dissimilar over time, often due to different environmental pressures or adaptations. This can be observed through homologous structures.

2. **Identifying Homologous Organs**: Homologous organs are those that share a common ancestry but have evolved to perform different functions. They have the same basic structural plan but have diverged in their functions.

3. **Examples of Homologous Organs**:
- The forelimbs of different animals serve different purposes:
- Bat's forelimb is adapted for flying.
- Cheetah's forelimb is adapted for running.
- Human's forelimb is adapted for grasping.
- Whale's forelimb is adapted for swimming.
- All these limbs have a similar bone structure (humerus, radius, ulna, carpals, metacarpals, and phalanges) but have different functions.

4. **Conclusion**: Since homologous organs demonstrate divergent evolution, the correct answer to the question is that divergent evolution can be seen in homologous organs.

5. **Eliminating Other Options**:
- **Analogous Organs**: These do not share a common ancestry and perform similar functions (e.g., sweet potato vs. potato). This represents convergent evolution, not divergent.
- **Artificial Breeding**: This is a human-directed process and does not illustrate natural divergent evolution.
- **Drug Resistance**: This is an example of adaptation in bacteria but does not directly relate to the concept of divergent evolution.

**Final Answer**: Divergent evolution can be seen in homologous organs.
