B. Darwins`s finches show convergent evolution.
C. Flying phalanger and Tasmanian wolf are result of different adaptive radiations.
D. Drawin's finches have evolved from insectivorous birds.

Answer

To solve the question regarding which statement is correct, we will analyze each statement provided in the question step by step.

### Step-by-Step Solution:

1. **Understanding the First Statement:**
- The first statement claims that lemurs and spotted cuskers are results of different adaptive radiation.
- **Analysis:**
- Lemurs are placental mammals, while spotted cuskers are Australian marsupials.
- They have evolved in different environments and have adapted to their respective habitats, which indicates they have undergone different adaptive radiations.
- **Conclusion:** This statement is correct.

2. **Understanding the Second Statement:**
- The second statement claims that Diamond Finches show convergent evolution.
- **Analysis:**
- Diamond Finches are known to have undergone divergent evolution rather than convergent evolution.
- They evolved from seed-eating birds into various forms based on their ecological needs, indicating divergence rather than convergence.
- **Conclusion:** This statement is incorrect.

3. **Understanding the Third Statement:**
- The third statement claims that flying phalanger and Tasmanian wolf are results of different adaptive radiation.
- **Analysis:**
- Both flying phalanger and Tasmanian wolf are Australian marsupials and share a common ancestor.
- Since they evolved from the same lineage, they are results of the same adaptive radiation, not different ones.
- **Conclusion:** This statement is incorrect.

4. **Understanding the Fourth Statement:**
- The fourth statement claims that Darwin finches evolved from insectivorous birds.
- **Analysis:**
- Darwin finches actually evolved from seed-eating birds, not insectivorous ones.
- This evolution led to various adaptations based on their feeding habits.
- **Conclusion:** This statement is incorrect.

### Final Conclusion:
- The only correct statement among the options provided is the **first statement** regarding lemurs and spotted cuskers.
