The Disproval Of Spontaneous Generation :: essays research papers

From the beginning of time it was believed that living things could come from pulseless things. This process was cognize as spontaneous contemporaries. However, in the middle of the 17th century and past through the next 100 years, this idea was disproved by three master(prenominal) experiments. We now know that a nonliving object or stem of objects can not turn into a living organism. Spontaneous generation is impossible in the atmosphere that we have today.In the early 1600s, batch believed that living organisms could evolve from nonliving organisms. They proved this by saying that if a piece of meat was left out uncovered, that maggots would appear in a few days. These worms did not come from anything that they could see, so they assumed they came from the nonliving meat. In 1668, a man named Redi designed and completed an experiment that showed how this was not true. He took two pieces of raw meat, and left them out. He covered virtuoso so that nothing could charm in, an d left the other one open. The open one grew maggots, and the covered one did not, proving that the dead meat did not produce the worms as they had previously thought.In the 1700s a man named Sp solelyanzani proved Redis idea to a further extent. He noticed microbial outgrowth on boiled pond water after being undefendable to the snap. To prove that this growth came from something living in the air, and not from the nonliving water, he designed an experiment. He boiled pond water to shovel in all the microbial growths. He then poured that water into two separate examen tubes. He sealed one so that no air could get in, and left one open to the air. The one that was left open easily became more and more cloudy with microbial growths. The sealed tube stayed as clear as it had been when it was boiled. This experiment proved that the growths could not come from nonliving organisms, but had to have been transported there through the air. When Spallanzani presented his results to the public, he was tyroized. Other scientists verbalise that he made the air unfit for living growth, and that they needed the air to change from nonliving to living.Pasteur did the third experiment, in 1862. He took Spallanzanis experiment, and the critics statements, and combined the two. He boiled pond water to kill all the living organisms.
