The correct Answer is:
To solve the question, we need to identify the term that describes the phenomenon where two species of different genealogy come to resemble each other as a result of adaptation. Here’s a step-by-step breakdown of the solution: ### Step 1: Understand the Question The question asks about a specific phenomenon in evolutionary biology where two unrelated species evolve to become similar due to similar environmental pressures. **Hint:** Focus on the relationship between species and their adaptations. ### Step 2: Recall Key Concepts In evolutionary biology, there are two main types of evolution based on the relationship between species: - **Divergent Evolution:** When two related species evolve different traits due to different environments. - **Convergent Evolution:** When unrelated species evolve similar traits because they adapt to similar environments. **Hint:** Think about how species can evolve under similar conditions despite having different ancestors. ### Step 3: Analyze the Options Given the context of the question, we need to determine which term fits the description of unrelated species becoming similar. The correct term is "convergent evolution." **Hint:** Look for a term that indicates similarity arising from adaptation rather than shared ancestry. ### Step 4: Define Convergent Evolution Convergent evolution occurs when species from different evolutionary backgrounds develop similar traits or adaptations in response to similar environmental challenges. This leads to the development of analogous structures, which serve similar functions but do not share a common origin. **Hint:** Remember that analogous structures are a result of convergent evolution, not divergent evolution. ### Step 5: Conclusion Thus, the phenomenon where two species of different genealogy come to resemble each other as a result of adaptation is termed **convergent evolution**. **Final Answer:** Convergent Evolution ---
