Spontaneous generation is a superseded scientific theory that held that living creatures could arise from nonliving matter and that such processes were commonplace and regular.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.
Spallanzani's first scientific work was in 1765 Saggio di osservazioni microscopiche concernenti il sistema della generazione de' signori di Needham, e Buffon (Essay on microscopic observations regarding the generation system of Messrs. Needham and Buffon) which was the first systematic rebuttal of the theory of the spontaneous generation. [3]
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.

Notable contributors to the theory include Justus Von Liebig and Louis Pasteur, the latter of whom developed a purely microbial basis for the fermentation process based on his experiments. 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]
Lamarck is usually remembered for his belief in the then commonly held theory of inheritance of acquired characteristics, and the use and disuse model by which organisms developed their characteristics. Lamarck incorporated this belief into his theory of evolution, along with other common beliefs of the time, such as spontaneous generation. [26]
John Turberville Needham FRS (10 September 1713 – 30 December 1781) was an English biologist and Roman Catholic priest.. He was first exposed to natural philosophy while in seminary school and later published a paper which, while the subject was mostly about geology, described the mechanics of pollen and won recognition in the botany community.
The new park is dedicated in honor of Holmdel resident and Nobel Laureate Dr. Robert Woodrow Wilson, who discovered the evidence for the Big Bang Theory of evolution at the site in 1964.
Van Leeuwenhoek disagreed with spontaneous generation, and by the 1680s convinced himself, using experiments ranging from sealed and open meat incubation and the close study of insect reproduction, that the theory was incorrect. [25] In 1668 Francesco Redi showed that no maggots appeared in meat when flies were prevented from laying eggs. [26]
