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

Options

A. If both assertion and reason are true and reason is the correct explanation of assertion.
B. If both assertion and reason are true but reason is not the correct explanation of assertion.
C. If assertion is true but reason is false.
D. If both assertion and 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.
- Convergent evolution occurs when different species independently evolve similar traits due to similar environmental pressures, despite having different ancestral origins.

2. **Analyzing the Tasmanian Wolf and Placental Wolf:**
- The Tasmanian wolf (Thylacine) is a marsupial that lived in Tasmania, while the placental wolf (Canis lupus) is a placental mammal found in various parts of the world.
- Despite their different classifications (marsupial vs. placental), both have evolved similar traits such as body shape and predatory behavior due to similar ecological niches.

3. **Understanding the Reason:**
- The reason states that more than one adaptive radiation has occurred in an isolated geographical area, leading to similar adaptations in different species.
- Adaptive radiation refers to the diversification of a group of organisms into forms filling different ecological niches. This can lead to similar adaptations in different species that occupy similar habitats.

4. **Connecting the Assertion and Reason:**
- Both the assertion and reason are true. The Tasmanian wolf and placental wolf are indeed examples of convergent evolution, and the reason provided explains how adaptive radiation in isolated geographical areas can lead to such similarities.

5. **Determining the Relationship:**
- The reason provides a correct explanation for the assertion, as it describes the process that leads to convergent evolution in isolated environments.

6. **Conclusion:**
- Therefore, the correct answer is that both the assertion and reason are true, and the reason is the correct explanation of the assertion.

**Final Answer:**
Both assertion and reason are true, and the reason is the correct explanation of the assertion.
