Darwin's finches were a good example of

Options

A. convergent evolution
B. industrial melanism
C. connecting link
D. adaptive radiation

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks what Darwin's finches are a good example of among the options provided: convergent evolution, industrial melanism, connecting link, or adaptive radiation.

2. **Identifying the Context**: Darwin's finches were discovered by Charles Darwin in the Galapagos Islands about 2 million years ago. They are known for their diverse adaptations.

3. **Analyzing the Options**:
- **Convergent Evolution**: This refers to different species developing similar traits due to similar environmental pressures, not applicable here as Darwin's finches have a common ancestor.
- **Industrial Melanism**: This phenomenon involves changes in species coloration due to industrial pollution, which does not relate to Darwin's finches.
- **Connecting Link**: This term typically refers to species that show characteristics of two different groups, which does not apply to the finches.
- **Adaptive Radiation**: This occurs when a single ancestor species diversifies into multiple forms to adapt to different environments or niches. This fits Darwin's finches as they evolved from a common ancestor into various species with different beak shapes, sizes, and feeding behaviors.

4. **Conclusion**: Based on the analysis, the correct answer is **D. Adaptive Radiation**. Darwin's finches exemplify adaptive radiation as they have diversified from a common ancestor into various species with distinct adaptations.
