Oparin and Haldane's theory of chemical evolution of life was experimentally supported by

Options

A. Landsteiner and Weiner
B. Hardy and Weinberg
C. Oparin and Sydney Fox
D. Miller and Urey

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks which scientists experimentally supported Oparin and Haldane's theory of chemical evolution of life.

2. **Background Knowledge**: Oparin and Haldane proposed a theory in the 1920s that life on Earth could have arisen from non-living matter through a gradual process. This theory is known as the Oparin-Haldane hypothesis.

3. **Identifying Key Scientists**: The key scientists associated with this theory are Alexander Oparin and J.B.S. Haldane. They suggested that life evolved from simple organic compounds.

4. **Experimental Support**: In 1953, scientists Stanley Miller and Harold Urey conducted an experiment that provided evidence for the Oparin-Haldane hypothesis. They demonstrated that organic molecules, essential for life, could be formed from inorganic substances under conditions that mimic those of early Earth.

5. **Conclusion**: Based on the information, the correct answer to the question is that the Oparin and Haldane's theory of chemical evolution of life was experimentally supported by Miller and Urey.

**Final Answer**: Miller and Urey.
