Out of the following , which , is an example of convergent evolution ?
(i) Eyes of octopus and mammals
(ii) Flipper of penguins and Dolphins
(iii) Sweet potato and potato

Options

A. i and iii
B. i and ii
C. ii and iii
D. i ,ii and iii

Answer

To determine which of the given options is an example of convergent evolution, we need to understand what convergent evolution entails.

### Step-by-Step Solution:

1. **Define Convergent Evolution**:
- Convergent evolution occurs when different species develop similar traits or adaptations in response to similar environmental challenges, despite having different evolutionary origins. This results in analogous structures that perform similar functions.

2. **Analyze Each Option**:
- **Option (i)**: Eyes of octopus and mammals.
- Both octopuses and mammals have eyes that serve the function of vision. However, their evolutionary origins are different. The eyes of octopuses and mammals are structurally different but functionally similar, making them an example of convergent evolution.

- **Option (ii)**: Flippers of penguins and dolphins.
- Penguins (birds) and dolphins (mammals) have flippers that serve the function of swimming. Despite their different evolutionary backgrounds, their flippers have evolved to perform the same function in their respective environments. This is also an example of convergent evolution.

- **Option (iii)**: Sweet potato and potato.
- Sweet potatoes are modified roots, while potatoes are modified stems. Although both serve the function of storage, they do not arise from different evolutionary paths to perform the same function in response to similar environmental pressures. Thus, they are not an example of convergent evolution.

3. **Conclusion**:
- The examples of convergent evolution from the options provided are:
- (i) Eyes of octopus and mammals
- (ii) Flippers of penguins and dolphins
- Therefore, both options (i) and (ii) are correct examples of convergent evolution.

### Final Answer:
The correct examples of convergent evolution are:
- (i) Eyes of octopus and mammals
- (ii) Flippers of penguins and dolphins
