Belief of Spontaneous Generation
Aristotle was the first to belive in Spontaneous Generation by compailing and expanding of other natural philosophers and explanations of the appareance of organisms -
Recipes for the Creation of Life
People started to belive in Spontaneous Generation and therefor decided to create their own recipes to creat life. A very known recipe was the recipe on how to "create" mice. The idea was to wrap sweaty rags around wheat and place them in an open jar and after 21 days, a mouse would have been created. -
An Experiment
In 1668, Francesco Redi, and Italian phyisician and scientist performed an experiment that proved Aristotle's Spontaneous Generation wrong.
He believed that the only way Spontanous Generation would work would be with microorganims and parasitic worms.
The experiment was designed to see if maggots were generated from rotten meat. Meat was placed in 3 flasks, a sealed one, an open one and one with a filter. Maggots only appeared in the open flask. -
Challenging Redi's Finding
English Scientist, John Needham challenged the discovery Redi made and placed gravy into a bottle and heated so that way he could kill all the living organisms and later on closed it. A few days later he noticed how there were microbes in the gravy and found out that life in fact can be created from inorganic matter. -
Louis Pasteur Disporved Spontaneous Generation
Louis Pasteur did the same experiment as John Needham but instead let the jars open. For this experiment he designed a bottle with a curve in the form of an S. The point of this bottle was that gravity would prevent access from airbone materials.
Broth was put into the bottle and heated it to kill everything.
There was no sign on life and that proved that microbes were airborn.
