Darwin's Finches are an excellent example of

Options

A. Convergent evolution
B. Industrial melanism,
C. Connecting link
D. Adaptive radiation

Answer

**Step-by-Step Solution:**

1. **Understanding Darwin's Finches**:
- Darwin's Finches are a group of bird species found on the Galápagos Islands. They are known for their diverse beak shapes and sizes, which have adapted to different feeding habits.

2. **Identifying the Options**:
- The question provides four options:
a) Convergent evolution
b) Industrial melanism
c) Connecting link
d) Adaptive radiation

3. **Analyzing Each Option**:
- **Option A: Convergent Evolution**:
- This refers to different species evolving similar traits due to similar environmental pressures. While birds and insects both have wings, they are not the same species. Therefore, this option does not apply to Darwin's Finches.

- **Option B: Industrial Melanism**:
- This is a phenomenon where darker individuals become more common in polluted environments. This concept does not relate to Darwin's Finches, as they are not primarily an example of this process.

- **Option C: Connecting Link**:
- A connecting link refers to organisms that exhibit traits of two different groups, like the duck-billed platypus. This does not apply to Darwin's Finches, which do not serve as a link between two distinct groups.

- **Option D: Adaptive Radiation**:
- This is the correct answer. Adaptive radiation occurs when a single ancestral species diversifies into a variety of forms to adapt to different environments. Darwin's Finches are a prime example of this as they evolved different beak shapes to exploit various food sources available in their habitats.

4. **Conclusion**:
- Based on the analysis, Darwin's Finches are an excellent example of **adaptive radiation**.

**Final Answer**: Darwin's Finches are an excellent example of **adaptive radiation**.
