The Disproval Of Spontaneous Generation

From the beginning, I think that living things come from inanimate objects. This process is called self-generation. However, in the mid-17th century, and in the following 100 years this idea was proved by three important experiments. We now know that inanimate objects or groups of objects can not be living creatures. It is impossible to realize it in the atmosphere we have today. In the early 1600s organisms were thought to evolve from non-living things.

In 1859, the young French chemist Louis Pasteur finally set the self-generation theory. The French Academy of Sciences sponsored the competition for the best experiments to prove that it also contests voluntary generations. Pasteur's triumph experiment is a variation of Needham and Sparanzani's method. He cooks the soup in a flask, heats the neck of the flask in the fire until it becomes flexible, and bends it in the form of S. Air can enter the flask but microorganisms in the air can not enter - they will settle under the neck with the force of gravity. As Pasteur predicts, there is no growth of microorganisms. When the Pasteur tool tilts the flask and moves the broth to the lowest position of the neck, the particles in the air settle and the broth soon becomes cloudy and life-threatening. Pasteur has challenged the theory of self-generation and proves that microorganisms are everywhere - even in the air - as convincingly

Pasteur's series of experiments undoubtedly refuted the self-generation theory and received the famous Alhumbert award from the Paris Academy of Sciences in 1862. In the subsequent lecture in 1864, Pasteur explained in detail "ex vivo ex vivo" ("Life is only coming from life"). In this lecture, Pasteur told his famous Swanneck flask experiment, "Life is a kind of bacteria and some bacteria are life. From the fatal blow of this simple experiment, Self-generated theory never recovers. "" Due to the reliability of Pasteur, it will never be

In the late 1950s, Louis Pasteur, a French scientist and father of microbiology, began to argue against the common theory that appeared. At that time many people thought that corruption - what shapes bread and rotten peaches - was magically born from bread and peach itself. By showing microorganisms from other places - they infected the body - Pasteurism established the basic mechanism of infection. He continues to develop early pasteurization technology, as well as rabies vaccine and anthrax vaccine.
