Select the correct pair

Answer

To solve the question "Select the correct pair," we will analyze each of the given options step by step.

### Step 1: Analyze Option 1 - Adaptive Radiation and Darwin's Finches
- **Definition of Adaptive Radiation**: This is the process where organisms diversify rapidly into a wide variety of forms to adapt to different environments.
- **Darwin's Finches**: These are a group of finch species found on the Galapagos Islands that evolved from a common ancestor. They exhibit a variety of beak shapes and sizes, which have adapted to different food sources.
- **Conclusion**: Since Darwin's finches are a classic example of adaptive radiation, this pair is **correct**.

### Step 2: Analyze Option 2 - Connecting Link and Peppered Moth
- **Definition of Connecting Link**: A connecting link is an organism that has characteristics of two different groups, serving as a transitional form.
- **Example of Connecting Link**: Archaeopteryx is a well-known connecting link between birds (Aves) and reptiles.
- **Peppered Moth**: This moth is known for its role in demonstrating natural selection due to industrial melanism, not as a connecting link.
- **Conclusion**: Since the connecting link is incorrectly paired with the peppered moth, this pair is **not correct**.

### Step 3: Analyze Option 3 - Industrial Melanism and Opium Pellets
- **Definition of Industrial Melanism**: This phenomenon refers to the darkening of populations of organisms (like the peppered moth) due to pollution, which affects their camouflage and survival.
- **Peppered Moth and Industrial Melanism**: The peppered moth is a classic example of industrial melanism, where the coloration of the moths changed due to soot on trees during the Industrial Revolution.
- **Opium Pellets**: This does not relate to industrial melanism.
- **Conclusion**: Since industrial melanism is not correctly paired with opium pellets, this pair is **not correct**.

### Final Conclusion
The only correct pair from the options given is:
- **Option 1: Adaptive Radiation and Darwin's Finches**.
