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

Options

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

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks about a phenomenon where two species of different genealogy come to resemble each other due to adaptation. This indicates that the species are not closely related but have developed similar traits because of similar environmental pressures.

2. **Analyzing the Options**:
- **Option A: Divergent Evolution**: This refers to the process where two or more related species become more different over time, often due to different environments. This does not fit the description in the question.
- **Option B: Microevolution**: This involves small-scale changes in gene frequencies within a population over time. It does not specifically address the resemblance between different species.
- **Option C: Co-evolution**: This is the process where two or more species influence each other's evolution, typically because they are closely related or interact closely. This does not apply to species of different genealogy.
- **Option D: Convergent Evolution**: This is the process where unrelated species develop similar traits or characteristics due to adapting to similar environments or ecological niches. This matches the description in the question perfectly.

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