Assertion :- Tasmanian wolf and Placental wolf are the good example of convergent evolution.
Reason :- More than one adaptive radiation apperared to have occured in an isolated geographical area, (representing different habitats) one can call this convergent evolution.

Options

A. If both Assertion & Reason are True & the Reason is a correct explanation of the Assertion.
B. If both Assertion & Reason are True but Reason is a not a correct explanation of the Assertion.
C. If Assertion is True but the Reason is False.
D. If both Assertion & Reason are false.

Answer

### Step-by-Step Solution:

1. **Understanding the Assertion**: The assertion states that the Tasmanian wolf and the placental wolf are good examples of convergent evolution. To evaluate this, we need to understand what convergent evolution means. It refers to the process where organisms from different evolutionary backgrounds develop similar traits or adaptations due to similar environmental pressures.

2. **Identifying the Organisms**: The Tasmanian wolf (Thylacine) is a marsupial, while the placental wolf (a term that could refer to species like the gray wolf) is a placental mammal. Both species exhibit similar physical traits and ecological roles despite their different evolutionary origins.

3. **Explaining Convergent Evolution**: The similarity in traits between the Tasmanian wolf and the placental wolf is a classic example of convergent evolution. They evolved similar adaptations (like body shape and predatory behavior) because they occupy similar ecological niches, even though they come from different ancestral lines.

4. **Understanding the Reason**: The reason provided states that adaptive radiation occurred in an isolated geographical area, leading to the development of similar traits in different species. Adaptive radiation is the process by which organisms diversify rapidly into a variety of forms to adapt to different environments.

5. **Connecting the Assertion and Reason**: The assertion and reason are connected because the adaptive radiation in Australia led to the evolution of marsupials and placental mammals that exhibit convergent traits. This means that the reason supports the assertion, as it explains how similar traits can arise in different species due to environmental pressures in a specific geographical area.

6. **Conclusion**: Both the assertion and the reason are true, and the reason correctly explains the assertion. Therefore, the answer to the question is that both statements are correct, and the reason is a valid explanation for the assertion.
