When two species of different genealogy come to resemble each other as a result of adaptation, the phenomenon is termed

Options

A. Convergent evolution
B. Divergent evolution
C. Microevolution
D. Co-evolution

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks about a phenomenon where two species with different genealogies (different ancestors) come to resemble each other due to adaptation.

2. **Identifying Key Terms**:
- "Different genealogy" indicates that the two species do not share a recent common ancestor.
- "Resemble each other" suggests that they have developed similar traits or characteristics.

3. **Exploring Evolutionary Concepts**:
- **Convergent Evolution**: This occurs when species from different evolutionary backgrounds develop similar traits as a result of adapting to similar environments or ecological niches.
- **Divergent Evolution**: This happens when two or more species that share a common ancestor evolve different traits, usually due to different environments.
- **Microevolution**: Refers to small-scale evolutionary changes typically observed within a species.
- **Co-evolution**: This is when two or more species influence each other's evolution, often seen in symbiotic relationships.

4. **Applying the Concepts**: Since the question specifies that the two species have different genealogies but resemble each other due to adaptation, this scenario best fits the definition of convergent evolution.

5. **Conclusion**: Therefore, the correct answer to the question is **convergent evolution**.
