Q. No.In 1953, S. L. Miller created primitive earth conditions in the laboratory and gave experimental evidence for the origin of the first form of life from pre-existing non-living organic molecules. The primitive earth conditions created include:
| 1. | low temperature, volcanic storms, an atmosphere rich in oxygen |
| 2. | low temperature, volcanic storms, reducing atmosphere |
| 3. | high temperature, volcanic storms, non-reducing atmosphere |
| 4. | high temperature, volcanic storms, reducing atmosphere containing CH4, NH3 etc. |
