Which theory, regarding the origin of life, is alternatively also called “panspermia”?
| 1. | Special Creation | 2. | Spontaneous Generation | 
| 3. | Cosmozoan Theory | 4. | Biochemical Evolution | 
The theory of spontaneous generation stated that:
| 1. | life arose from living forms only | 
| 2. | life can arise from both living and non-living | 
| 3. | life can arise from non-living things only | 
| 4. | life arises spontaneously, neither from the living nor from the non-living | 
| I: | The first form of life could have come from pre-existing non-living organic molecules (e.g. RNA, protein, etc.) | 
| II: | The formation of life was preceded by chemical evolution, i.e., the formation of diverse organic molecules from inorganic constituents. | 
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. | 
| I: | Fitness, according to Darwin, refers ultimately and only to reproductive fitness. | 
| II: | Those who are a better fit in an environment, leave more progeny than others. | 
| 1. | Both Statement I and Statement II are correct and Statement II explains Statement I. | 
| 2. | Statement I is correct and Statement II is incorrect. | 
| 3. | Statement I is incorrect and Statement II is correct. | 
| 4. | Both Statement I and Statement II are correct but Statement II does not explain Statement I. |

Palaeontological evidence for evolution refers to the:
| 1. | development of the embryo | 2. | homologous organs | 
| 3. | fossils | 4. | analogous organs |
