Closely related varying different in trait expresses

Options

A. Convergent evolution
B. Divergent evolution
C. Parallel evolution
D. None of these

Answer

To solve the question "Closely related varying different in trait expresses," we need to identify the type of evolution that describes closely related species that exhibit differences in traits. Here’s a step-by-step breakdown of the solution:

### Step-by-Step Solution:

1. **Understanding the Question**: The question refers to closely related species that exhibit variations in their traits. This implies that these species share a common ancestor but have diverged in their characteristics.

2. **Identifying Types of Evolution**:
- **Convergent Evolution**: This occurs when unrelated species develop similar traits due to adapting to similar environments. Since the question specifies "closely related," this option does not fit.
- **Divergent Evolution**: This occurs when closely related species evolve different traits. They share a common ancestor but adapt to different environments or conditions, leading to variations in traits.
- **Parallel Evolution**: This involves related species evolving similar traits from a common ancestor, but it does not apply here since the question emphasizes differences in traits.

3. **Choosing the Correct Answer**: Given that the question specifies "closely related varying different in trait," the correct type of evolution is **Divergent Evolution**. This is because it describes how closely related species can evolve different traits over time.

4. **Conclusion**: The correct answer to the question is **Divergent Evolution**.

### Final Answer:
The correct type of evolution that describes closely related species varying in traits is **Divergent Evolution**.
