Most advanced theory of origin of life is that of

Options

A. Catastrophic
B. Haldane and Oparin
C. Cosmozoic
D. Spontaneous

Answer

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

1. **Understanding the Question**: The question asks for the most advanced theory regarding the origin of life.

2. **Identifying Relevant Theories**: The two prominent theories related to the origin of life discussed in the transcript are those proposed by Haldane and Oparin.

3. **Overview of Haldane and Oparin's Theory**:
- Haldane and Oparin suggested that life originated from abiogenic (non-living) materials.
- They proposed that the primitive atmosphere of Earth contained essential gases such as water vapor, nitrogen, ammonia, and methane.

4. **Chemical Reactions Leading to Organic Compounds**:
- According to Oparin, these gases reacted with each other, leading to the formation of organic compounds, which are crucial for the development of living organisms.
- Haldane emphasized that the primordial soup (the early Earth's environment) acted as a laboratory for these chemical reactions.

5. **Energy Source for Reactions**:
- The energy necessary for these reactions was provided by the Sun, particularly through ultraviolet (UV) radiation.

6. **Conclusion**: Based on the information provided, the most advanced theory of the origin of life is attributed to Haldane and Oparin.

**Final Answer**: The most advanced theory of the origin of life is that of Haldane and Oparin.
