Pasteur decided to partake in this competition to combat Pouchet's support of spontaneous generation. He designed an experiment to deny the notion of spontaneous generation. He thought that if spontaneous generation were true in which air itself could cause generation, then all sterile swan neck flasks that were later exposed to air would ...
Spontaneous generation is a superseded scientific theory that held that living creatures could arise from nonliving matter and that such processes were commonplace and regular.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.

Until the 19th century, there was considerable acceptance of the theory of spontaneous generation, the idea that "lower" animals, such as insects or rodents, arose from decaying matter. [10] However, several experiments in the 19th century – particularly Louis Pasteur 's swan neck flask experiment in 1859 [ 11 ] — disproved the theory that ...
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 ...
Many discarded explanations were once supported by a scientific consensus, but replaced after more empirical information became available that identified flaws and prompted new theories which better explain the available data. Pre-modern explanations originated before the scientific method, with varying degrees of empirical support.
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.
