Monera are evolved from

Options

A. Progenote
B. Protista
C. Viruses
D. All the above

Answer

**Step-by-Step Solution:**

1. **Understanding Monera**: Monera is a kingdom that primarily consists of prokaryotic organisms, which are unicellular and lack a defined nucleus. The most common examples of organisms in this kingdom are bacteria.

2. **Identifying the Origin**: The question asks from where Monera evolved. To answer this, we need to consider the evolutionary history of life on Earth.

3. **Considering Progenote**: The term "progenote" refers to the last universal common ancestor (LUCA) of all living organisms. It is a hypothetical organism from which all life forms, including Monera, evolved.

4. **Evaluating Other Options**:
- **Protista**: This kingdom consists of eukaryotic organisms, which are more complex than prokaryotes. Therefore, Monera did not evolve from Protista.
- **Viruses**: Viruses are not classified as living organisms in the traditional sense and can be considered as both living and non-living entities. Hence, Monera did not evolve from viruses.
- **All of the Above**: This option implies that Monera evolved from all the previously mentioned categories, which is incorrect.

5. **Conclusion**: Based on the evaluation, the correct answer is that Monera evolved from the progenote, which is the last universal common ancestor of all living beings.

**Final Answer**: Monera evolved from the progenote.
