The correct Answer is:
### Step-by-Step Solution 1. **Understanding the Question**: The question asks how hummingbirds and hawks illustrate a specific evolutionary concept. The options provided are convergent evolution, homology, adaptive radiation, and parallel evolution. 2. **Identifying Common Ancestors**: Both hummingbirds and hawks share a common ancestor. This is an important point because it indicates that they have diverged from a similar starting point. 3. **Analyzing Environmental Adaptations**: Hummingbirds and hawks have adapted to different environments. This adaptation occurs due to the need to survive and thrive in varying ecological niches. 4. **Defining Adaptive Radiation**: Adaptive radiation is a process where organisms diversify rapidly from an ancestral species into a wide variety of forms to adapt to different environments. This is what has happened with hummingbirds and hawks. 5. **Eliminating Other Options**: - **Convergent Evolution**: This involves different species developing similar traits independently, without a common ancestor. This is not applicable here since both birds share a common ancestor. - **Homology**: This refers to structures that are similar due to shared ancestry but may serve different functions. This does not apply as hummingbirds and hawks have evolved differently. - **Parallel Evolution**: This occurs when two different species evolve similar traits in similar environments. This is also not applicable here since both birds share a common ancestor. 6. **Conclusion**: Given the analysis, hummingbirds and hawks illustrate **adaptive radiation** as they have evolved differently from a common ancestor to adapt to their respective environments. ### Final Answer: Hummingbirds and hawks illustrate **adaptive radiation**. ---
