When the different structure evolve in th same direction due to adaptation to similar needs , it is than referred to as ?

Options

A. adaptive convergence
B. divergent evolution
C. homology
D. analogy

Answer

To solve the question, "When the different structures evolve in the same direction due to adaptation to similar needs, it is then referred to as?", we can break down the reasoning into several steps:

### Step-by-Step Solution:

1. **Understanding the Question**: The question asks about the evolution of different structures that arise in response to similar needs. This indicates that we are looking for a term that describes this phenomenon.

2. **Identifying Key Terms**:
- **Adaptive Convergence**: This term suggests that different species adapt similarly due to similar environmental pressures.
- **Adaptive Radiation**: This refers to the evolution of different species from a common ancestor, adapting to various environments, which is not what the question is asking.
- **Divergent Evolution**: This involves similar structures evolving in different directions due to different needs, which is opposite to what the question describes.
- **Analogy**: This term refers to structures that evolve independently in different species but serve similar functions due to similar environmental pressures.

3. **Analyzing the Options**:
- Since the question specifies "different structures evolve in the same direction due to adaptation to similar needs," we need to focus on the concept of structures that are not homologous (not derived from a common ancestor) but serve similar functions.

4. **Conclusion**: The correct term that fits the description in the question is **Analogy**. This term is used to describe the phenomenon where different species develop similar traits or structures independently as a response to similar environmental challenges.

### Final Answer:
The answer is **Analogy**.
