Monera evolved from

Options

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

Answer

To answer the question "Monera evolved from," we can follow these steps:

### Step 1: Understand the Kingdom Monera
Monera is the first kingdom in the five-kingdom classification system proposed by Robert Whittaker. It primarily consists of prokaryotic organisms, which are unicellular and lack a true nucleus.

**Hint:** Remember that Monera is characterized by its prokaryotic nature and unicellularity.

### Step 2: Identify the Characteristics of Monera
Organisms in the Monera kingdom include bacteria. These organisms are simple in structure and are considered the most primitive forms of life.

**Hint:** Focus on the fact that Monera includes bacteria, which are essential for understanding its evolutionary background.

### Step 3: Consider the Evolutionary Background
The question asks about the evolutionary origin of Monera. To find this, we need to look at the concept of the last universal ancestor (LUA). This ancestor is believed to be the common ancestor from which all life forms, including Monera, have evolved.

**Hint:** The last universal ancestor is a key concept in understanding the evolution of all life forms.

### Step 4: Identify the Correct Evolutionary Source
The video transcript mentions that Monera evolved from "progenome." This term refers to the hypothetical early form of life that preceded modern cellular life forms. It is considered a precursor to both prokaryotic and eukaryotic organisms.

**Hint:** The term "progenome" is crucial for identifying the evolutionary source of Monera.

### Step 5: Eliminate Incorrect Options
The transcript discusses other options (like "protein" and "widest") that do not relate to the evolutionary origin of Monera. By eliminating these, we can confirm that "progenome" is the correct answer.

**Hint:** Cross-check the provided options against the characteristics of Monera to eliminate incorrect choices.

### Conclusion
The correct answer to the question "Monera evolved from" is **progenome**.
