Question

Now the basis of origin of life is

• A. Spontaneous generation
• B. God's desire
• C. Sunlight on mud
• D. None of the above

Answer 1

The correct option is D None of the above

Anaximander and Aristotle was main propounder of theory of spontaneous generation which assume origin of life from non living substances. It assumes origin of frog and toads from mud that of microorganisms from air and so on. Concept of spontaneous generation was experimentally refuted by Pasteur, Spallanzani and F. Redi. Concept of special creation assumes origin of all life forms by God’s desire and considers the origin of life as spiritual or supernatural event. Origin of life by God’s desire was refuted by scientific knowledge based upon fossil records and data from comparative anatomy, morphology and embryology. Origin of life on primitive earth occurred by chemical synthesis of organic compounds from primitive gases and inorganic elements followed y biogenesis. The reducing atmosphere and absence of life on primitive earth favoured origin of life which is not possible in present day oxidizing atmosphere because the compounds are readily oxidized as soon as they are formed. Thus, now life is not originating.

Therefore, the correct answer is option D.
