Spontaneous generation is a superseded scientific theory that held that living creatures could arise from nonliving matter and that such processes were commonplace and regular. It was hypothesized that certain forms, such as fleas , could arise from inanimate matter such as dust, or that maggots could arise from dead flesh.
Antonie van Leeuwenhoek. Traditional religion attributed the origin of life to deities who created the natural world. Spontaneous generation, the first naturalistic theory of abiogenesis, goes back to Aristotle and ancient Greek philosophy, and continued to have support in Western scholarship until the 19th century.

The founder of experimental biology and the first person to challenge the theory of spontaneous generation by demonstrating that maggots come from eggs of flies. [57] Population genetics: Ronald A. Fisher, Sewall Wright, J. B. S. Haldane [58] Protozoology: Antonie van Leeuwenhoek (1632–1723) [9] First to produce precise, correct descriptions ...
Lamarck saw spontaneous generation as being ongoing, with the simple organisms thus created being transmuted over time becoming more complex. He is sometimes regarded as believing in a teleological (goal-oriented) process where organisms became more perfect as they evolved, though as a materialist, he emphasized that these forces must originate ...
Louis Pasteur ForMemRS (/ ˈ l uː i p æ ˈ s t ɜːr /, French: [lwi pastœʁ] ⓘ; 27 December 1822 – 28 September 1895) was a French chemist, pharmacist, and microbiologist renowned for his discoveries of the principles of vaccination, microbial fermentation, and pasteurization, the last of which was named after him.
Pasteur's work on fermentation later led to his development of the germ theory of disease, which put the concept of spontaneous generation to rest. [1] Although the fermentation process had been used extensively throughout history prior to the origin of Pasteur's prevailing theories, the underlying biological and chemical processes were not ...

He was then able to disprove spontaneous generation. Only the broth exposed to the particles and microbes around it, grew bacteria at a quick rate. [52] In 1861, Pasteur named his theory of contamination "Germ Theory." He stated the opposite of the miasma theory: microbe carried by the air reacted with live substances causing contamination.
