Who gave the theory which is known as primary abiogenesis

Options

A. Oparin
B. Haldane
C. Miller
D. Urey

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks about the scientist who proposed the theory known as primary abiogenesis. Abiogenesis refers to the origin of life from non-living matter.

2. **Identifying Key Terms**:
- **Primary Abiogenesis**: This theory suggests that life originated from simple organic compounds that formed in the early Earth environment.
- **Options Given**: O'Barren, Haldane, Miller, Urey.

3. **Analyzing the Options**:
- **O'Barren**: This scientist is credited with the theory of primary abiogenesis.
- **Haldane**: He proposed the "hot dilute soup" theory, which is related but not the same as primary abiogenesis.
- **Miller and Urey**: They conducted experiments that supported the theory of chemical evolution, but they did not propose the primary abiogenesis theory.

4. **Conclusion**: Based on the analysis, the correct answer to the question is **O'Barren**, as he is the scientist who gave the theory known as primary abiogenesis.

5. **Final Answer**: The theory known as primary abiogenesis was given by **O'Barren**.
