Origin of first life is

Options

A. Biogeny
B. Biopoiesis
C. Cognogeny
D. Chemogeny.

Answer

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

1. **Understanding the Options**: The question presents four options regarding the origin of the first life:
- Option 1: Biogenesis
- Option 2: Biopoiesis
- Option 3: Cognizance
- Option 4: Chemogenesis

2. **Analyzing Biogenesis**:
- Biogenesis refers to the process where living organisms arise from pre-existing living organisms. This concept is crucial in understanding the origin of life as it suggests that life comes from life.

3. **Evaluating Biopoiesis**:
- Biopoiesis is often associated with the idea of life originating from non-living matter. This concept is more aligned with theories of abiogenesis, which is not the correct answer for the origin of the first life.

4. **Considering Cognizance**:
- Cognizance relates to the awareness or understanding of organisms and their diversification, particularly in protozoa and metazoa. This term does not pertain to the origin of life, making it an incorrect choice.

5. **Reviewing Chemogenesis**:
- Chemogenesis, also known as chemical evolution, refers to the process by which simple chemical compounds led to the formation of complex organic molecules. While this concept is related to the origin of life, it is not the accepted term for the first life.

6. **Conclusion**:
- Based on the analysis, the correct answer to the question "Origin of first life is" is **Biogenesis** (Option 1), as it accurately describes the process of life arising from existing life.
