Development of unrelated groups of animals along parallel lines in adaptation to a similar environment is called

Options

A. Adaptive convergence
B. adaptive radiation
C. Adaptive divergence
D. Adaptive induction.

Answer

To solve the question, "Development of unrelated groups of animals along parallel lines in adaptation to a similar environment is called," we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Question**: The question asks for a term that describes the phenomenon where unrelated groups of animals evolve similarly due to similar environmental conditions.

2. **Identifying Key Concepts**:
- **Unrelated Groups of Animals**: This indicates that the animals in question do not share a recent common ancestor.
- **Parallel Evolution**: This suggests that these unrelated groups are evolving in similar ways due to similar environmental pressures.

3. **Defining the Terms**:
- **Adaptive Evolution**: This refers to the process where organisms adapt to their environment.
- **Convergent Evolution**: This is a specific type of adaptive evolution where different species evolve similar traits independently, often because they live in similar environments.

4. **Connecting the Concepts**: Since the question specifies "development of unrelated groups of animals along parallel lines," it aligns with the concept of **convergent evolution**. This is because these groups are adapting similarly to the same environmental conditions despite being unrelated.

5. **Final Answer**: The term that describes this phenomenon is **Convergent Evolution**.
