Convergent evolution is shown by `:`

Options

A. rabbit and dog
B. starfish and jellyfish
C. fish and whale
D. bacteria and Amoeba

Answer

**Step-by-Step Solution:**

1. **Understanding Convergent Evolution:**
- Convergent evolution refers to the process where different species independently evolve similar traits or functions, despite having different evolutionary origins. This typically occurs in response to similar environmental pressures or challenges.

2. **Identifying Key Characteristics:**
- In convergent evolution:
- The species involved are widely different in origin.
- They develop similar functions or adaptations.
- Their structures are different, even though they perform similar functions.

3. **Analyzing the Options:**
- We need to evaluate the provided options based on the characteristics of convergent evolution.

- **Option 1: Rebitant Dog**
- Both are mammals, meaning their origin is similar. This does not fit the criteria for convergent evolution.

- **Option 2: Starfish and Jellyfish**
- Both belong to similar aquatic environments but have different origins. However, they are not widely different enough to be considered convergent evolution.

- **Option 3: Fish and Whale**
- Fish (a type of aquatic animal) and whales (mammals) are from different evolutionary origins. They have adapted to similar aquatic environments, performing similar functions (swimming), despite their different structures. This fits the criteria for convergent evolution.

- **Option 4: Bacteria and Amoeba**
- Both belong to the domain of single-celled organisms, and their origins are more similar than different. This does not represent convergent evolution.

4. **Conclusion:**
- The correct answer is **Option 3: Fish and Whale**, as they exemplify convergent evolution through their adaptation to similar functions in an aquatic environment despite being from different evolutionary lineages.
