Which of the following is not the result of convergent evolution?

Options

A. Forelimbs of whales and bats
B. Flippers of penguins and dolphins
C. Potato and sweet potato
D. Eye of the octopus and mammals

Answer

To answer the question "Which of the following is not the result of convergent evolution?" we need to analyze each option provided:

1. **Forelimbs of whales and bats**:
- Whales (mammals) and bats (also mammals) have forelimbs that are structurally similar (homologous) because they share a common ancestor. However, they have adapted to different functions (swimming in whales and flying in bats). This is an example of divergent evolution, not convergent evolution.

2. **Flippers of penguins and dolphins**:
- Penguins (birds) and dolphins (mammals) have flippers that serve a similar function (swimming) but evolved independently in different lineages. This is an example of convergent evolution, as they developed analogous structures.

3. **Potato and sweet potato**:
- Potatoes (Solanum tuberosum) and sweet potatoes (Ipomoea batatas) are both storage organs (tubers) that serve a similar function (storing energy). However, they come from different plant families and are an example of convergent evolution.

4. **Eye of the octopus and mammals**:
- The eyes of octopuses and mammals are structurally different but serve the same function (vision). They evolved independently in different lineages, which is another example of convergent evolution.

Based on this analysis, the option that is **not** the result of convergent evolution is:

**Correct Answer: Forelimbs of whales and bats.**
