understanding of science in his time rested on the assumption that living
beings had a very simple structure. Since medieval times, spontaneous
generation, the theory asserting that non-livingmaterials came together toform living organisms, hadbeen widely accepted. It was commonly believed thatinsects came into being from food leftovers, and micefrom wheat. Interesting experiments were conductedto prove this theory. Some
wheat was placed on a dirtypiece of cloth, and it was believed that mice wouldoriginate from it aftera.
Pasteur invalidated the claim that "inanimate
matter can create life", which constituted the
groundwork of the theory of evolution.
while.
Similarly, worms developing in meat was assumed to be evidence of
spontaneous generation. However, only some time later was it
understood that worms did not appear on meat spontaneously, but were
carried there by flies in the form of larvae, invisible to the naked eye.
Even in the period when Darwin wrote The Origin of Species, the
belief that bacteria could come into existence from non-living matter was
widely accepted in the world of science.
However, five years after Darwin's book was published, the
discovery of Louis Pasteur disproved this belief, which constituted the
groundwork of evolution. Pasteur summarized the conclusion he reached
after time-consuming studies and experiments: "The claim that inanimate
matter can originate life is buried in history for good."11
Advocates of the theory of evolution resisted the findings of Pasteur
for a long time. However, as the development of science unraveled the
complex structure of the cell of a living being, the idea that life could come
into being coincidentally faced an even greater impasse
