- Louis Pasteur by careful experimentation demonstrated that life comes only from pre existing life.
- He showed that in pre sterilised flasks, life did not come from killed yeast while in another flask open to air, new living organisms arose from ‘killed yeast’.
- Spontaneous generation theory was dismissed once and for all.

Theory of Spontaneous Generation Rejection Explanation
Theory of Spontaneous Generation:
- The theory of spontaneous generation proposed that life could arise from non-living or inanimate matter through a process of spontaneous generation.
Reasons for Rejection:
- Lack of Experimental Evidence:
- One of the main reasons why the theory of spontaneous generation was rejected was due to the lack of experimental evidence to support it.
- Scientists found no concrete proof that life could spontaneously arise from non-living matter.
- Biogenesis Concept:
- The concept of biogenesis, which states that living organisms can only arise from pre-existing living organisms, gained more support as it was backed by experimental evidence.
- This contradicted the idea of spontaneous generation.
- Origin of First Life on Earth:
- The theory of spontaneous generation did not provide a satisfactory explanation for the origin of the first life on Earth.
- It failed to address the specific mechanisms by which life could arise from non-living matter.
- Origin of Life from Outer Space:
- Some proponents of the theory of spontaneous generation suggested that life could have originated from outer space.
- However, this idea lacked substantial evidence and was not widely accepted by the scientific community.
In conclusion, the theory of spontaneous generation was rejected primarily because it lacked experimental evidence to support its claims and failed to provide a comprehensive explanation for the origin of life on Earth. The concept of biogenesis, which has experimental backing, gained more acceptance in the scientific community.
