Evolution of different mammals residing in different habitats like air, land and water is an example of:

Options

A. Adaptive radiation
B. Convergent evolution
C. Micro evolution
D. Adaptive convergence

Answer

**Step-by-Step Solution:**

1. **Understanding the Question:**
The question asks about the evolution of different mammals that inhabit various environments such as air, land, and water. We need to identify the evolutionary concept that best describes this phenomenon.

2. **Identifying Key Terms:**
- The term "mammals" indicates we are dealing with a specific class of animals.
- The phrase "different habitats" suggests that these mammals have adapted to distinct environments.

3. **Considering the Options:**
The options provided are:
- Adaptive Radiation
- Convergent Evolution
- Microevolution
- Adaptive Convergence

4. **Analyzing Adaptive Radiation:**
- Adaptive radiation occurs when organisms from a common ancestor evolve and diversify into various forms to adapt to different environments. This is relevant here as mammals have evolved to occupy air, land, and water.

5. **Analyzing Convergent Evolution:**
- Convergent evolution refers to different species evolving similar traits independently, often due to similar environmental pressures. This does not apply here since we are discussing mammals from a common ancestor.

6. **Analyzing Microevolution:**
- Microevolution involves small evolutionary changes within a species or population over time. Since we are discussing different mammals, this option is not suitable.

7. **Analyzing Adaptive Convergence:**
- Adaptive convergence is similar to convergent evolution, focusing on different species adapting to similar environments. This does not fit our scenario either.

8. **Conclusion:**
Based on the analysis, the correct answer is **Adaptive Radiation**. This term accurately describes how mammals have evolved from a common ancestor to adapt to various habitats.

**Final Answer: Adaptive Radiation**
