The abiogenesis theory of origin supports:
Correct answer: A. Spontaneous generation
- A. Spontaneous generation
- B. Origin of life from blue-green algae
- C. Origin of life is due to pre-existing organisms
- D. Organic evolution is due to chemical reactions
Explanation
The abiogenesis theory of origin states that life originated from non-living things in a spontaneous manner. This theory was supported by early Greek philosophers. In ancient Egypt, it was believed that the mud of the Nile River could give rise to frogs, snakes, mice, and even crocodiles when warmed by the sun. Van Helmont believed that human sweat and wheat grains could give rise to organisms. Hence, the correct answer is 'Spontaneous generation'.

About Concept of Evolution
Evolution is the heritable change in populations over generations, driven by mutation, recombination, natural selection, genetic drift and reproductive isolation. Questions examine variation, adaptation, survival and reproduction, speciation, fossil and anatomical evidence, and the difference between individual acclimatization and evolutionary change in a population.
