The correct Answer is:
To determine which of the following sets is not an example of divergent evolution, we first need to understand the concepts of divergent and convergent evolution. ### Step-by-Step Solution: 1. **Define Divergent Evolution**: - Divergent evolution occurs when two or more related species become more dissimilar over time, often due to different environments or functions. They share a common ancestor but develop different traits and functions. 2. **Define Convergent Evolution**: - Convergent evolution happens when unrelated species develop similar traits or functions due to similar environmental pressures, despite having different evolutionary origins. 3. **Analyze the Options**: - **Option A: Vertebrate heart or brain**: - These organs have a common evolutionary origin (vertebrates) but perform different functions (circulation vs. processing information). This is an example of divergent evolution. - **Option B: Marsupials and Darwin finches**: - Both groups have evolved from a common ancestor but have adapted to different environments and functions. This is also an example of divergent evolution. - **Option C: Sweet potato and potato**: - Both sweet potato and potato are used for storage (similar function) but come from different plant families. Since they have similar functions, this is an example of convergent evolution. - **Option D: Forelimb of vertebrates**: - The forelimbs of various vertebrates (like humans, whales, and bats) have a common origin but have adapted to different functions (manipulation, swimming, flying). This is an example of divergent evolution. 4. **Conclusion**: - The only option that does not represent divergent evolution is **Option C: Sweet potato and potato**, as they exhibit convergent evolution due to their similar function of storage. ### Final Answer: **Option C: Sweet potato and potato** is not an example of divergent evolution. ---
