In some animals of different groups differents structure developed along same direction due to Adaptation to same needs this is called as :

Options

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

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks about a phenomenon where different animals from various groups develop similar structures due to adaptation to the same needs.

2. **Identifying Key Terms**: The key terms in the question are "different groups," "different structures," "same direction," and "adaptation to same needs." This indicates that we are looking for a type of evolutionary process that leads to similar adaptations in unrelated species.

3. **Analyzing the Options**:
- **Divergent Evolution**: This refers to two or more related species evolving different traits from a common ancestor. This does not fit our scenario since we are discussing unrelated species.
- **Convergent Evolution**: This occurs when unrelated species develop similar traits or adaptations due to similar environmental pressures or needs. This fits our scenario.
- **Parallel Evolution**: This involves related species evolving similar traits while remaining distinct, which does not apply here as we are discussing different groups.
- **None of These**: This option can be disregarded since we have identified a suitable term.

4. **Example for Clarity**: An example of convergent evolution is the wings of birds and butterflies. Both serve the function of flight but have evolved independently in two different groups (birds being vertebrates and butterflies being insects). Their wing structures are different, yet they fulfill the same purpose due to adaptation.

5. **Conclusion**: Based on the analysis, the correct answer to the question is **Convergent Evolution**.
