Answer

**Step-by-Step Solution:**

1. **Identify the Subject**: The question asks about Darwin finches, which are a group of birds studied by Charles Darwin.

2. **Understand the Context**: These finches were observed during Darwin's voyage to the Galapagos Islands. They are significant in the study of evolution.

3. **Define Key Terms**:
- **Adaptive Radiation**: This is the process where organisms diversify rapidly into a variety of forms to adapt to different environments.
- **Divergent Evolution**: This refers to the process where two or more related species become more dissimilar over time, often due to different environmental pressures.

4. **Apply the Concepts**: Darwin finches are a classic example of adaptive radiation because they evolved from a common ancestor into multiple species that adapted to different ecological niches in the Galapagos Islands.

5. **Conclude**: Therefore, Darwin finches exemplify both adaptive radiation and divergent evolution.

**Final Answer**: Darwin finches are an example of adaptive radiation and divergent evolution.
