Convergent evolution is shown by

Options

A. Homologous organ
B. Analogous organ
C. Vestigial organ
D. All of these

Explanation

**Step-by-Step Text Solution:**

1. **Understanding Convergent Evolution**:
Convergent evolution refers to the process where organisms from different evolutionary backgrounds develop similar traits or adaptations in response to similar environmental challenges. This results in analogous structures that perform similar functions but do not share a common ancestor.

2. **Identifying the Options**:
The question provides several options to choose from regarding which type of evolution is shown by convergent evolution. The options typically include:
- Homologous organs
- Analogous organs
- Vestigial organs

3. **Analyzing Homologous Organs**:
Homologous organs are those that arise from a common ancestor and exhibit divergent evolution. They have similar structures but serve different functions. For example, the forelimbs of humans, bats, whales, and cheetahs are homologous organs. They share a common structural plan but have evolved to perform different functions.

4. **Analyzing Analogous Organs**:
Analogous organs, on the other hand, are those that perform similar functions but do not share a common ancestry. An example is the sweet potato and the potato. Despite their different origins (sweet potato being a root and potato being a stem), both serve the same function of food storage. This is a clear example of convergent evolution.

5. **Analyzing Vestigial Organs**:
Vestigial organs are remnants of organs that had a function in ancestral species but have lost their original function in the current species. They do not relate to convergent evolution. For instance, humans have vestigial organs like the wisdom tooth and the coccyx bone.

6. **Conclusion**:
Based on the analysis, the correct option that shows convergent evolution is the one that refers to analogous organs. Therefore, the answer to the question is option number 2, which represents analogous organs.
