Francesco Redi's experiment. He was an Italian physician. He was the first scientist to challenge the theory of spontaneous generation by demonstrating that maggots come from eggs of flies.
At the time, prevailing wisdom was that maggots arose spontaneously from rotting meat. He took three jars: in the first jar, he put an unknown object; in the second, a dead fish; in the last, a raw chunk of meat.
Redi covered the tops of the first two jars with fine gauze that only air could get into it. He left the last one open. After several days, he saw maggots appear on the objects in the open jars, on which flies had been able to land, but not in the gauze-covered jars.

What were the experiments that were used to explain the concept of spontaneous generation?
Francesco Redi - One of the first to disprove spontaneous generation. An Italian doctor who proved maggots came from flies. (Italian 1668) Lazzaro Spallanzani - One of the first to disprove spontaneous generation. An Italian scientist who proved microorganisms could be killed by boiling. (Italian 1767) Louis Pasteur - One of the first to disprove spontaneous generation. A French scientist who proved that micro organisms was carried by dust not air. (French 1864) In 1953 Miller and Urey experiment called as electric spark experiment shows how process of formation of organic compounds or first living cell formation occur.
Is spontaneous generation the same as the current understanding of evolution?
No. Evolution explains how and why organisms change over time. It makes no difference to evolution how organisms are generated.
What does spontaneous generation mean?
NoteNote that spontaneous generation and abiogenesis are distinct and separate concepts. For information on abiogenesis, see links below.AnswerSpontaneous generation is the obsolete idea that complex, modern organisms can form overnight from non-living things, hypothesized by Aristotle. For example, people used to think that maggots came from raw meat.AnswerSpontaneous Generation was the theory that complex, modern organisms formed overnight from non-living things. It was disproved by many people, some including Francesco Redi (1668) and Lazzaro Spallanzani (1768). Redi disproved Spontaneous Generation by putting some decaying meat in 2 jars, then covered one of them. When fly maggots appeared in only the uncovered jar, he had enough evidence to prove that the flies came from eggs and not the decaying meat because if the flies came from the meat, there would be flies in both jars. Spallanzani disproved Spontaneous Generation by putting heated broth in 2 sealed flasks, and covered on of them, somewhat like what Redi did, but with different materials. He concluded that Spontaneous Generation was illogical because the uncovered flask had microorganisms, and the sealed one did not.
What theory replaced the spontaneous generation?
The theory that replaced the theory of spontaneous generation is the theory of biogenesis. Biogenesis is the production of new living organisms or organelles.
How do you flask 2 results disprove spontaneous generation?
If nothing is growing in your flask then that means no organisms came from non-living matter, therefore the idea that organisms come from non-living matter is disproved. Students who are using Ask.com to search for answers in their APEX coursework should note that they need to paraphrase their answers so their teachers (who are not stupid) do not give them back revisions for plagiarism.
What reason did Pasteur do his experiment with flask?
He wanted to disprove spontaneous generation; that micro organisms were not carried by air, but were deposited from dust.
What is the mistaken idea that living organisms?
Spontaneous generation

What is the idea called a spontaneous generation?
A spontaneou generation is the idea that organisms originate directly from nonliving matter
Who was the scientist who proved that large organisms are not produced by spontaneous generation?
Francesco Redi
Was Pasteur the doctor who showed that maggots hatch from eggs that flies lay on meat and not from the meat itself?
Francesco Redi disproved the theory of spontaneous generation in larger organisms during the 1600s with this experiment. By using flasks containing meat -- one open and one sealed -- Redi discovered that maggots only appeared on the uncovered meat that could be accessed by flies. The maggots were hatching from eggs laid on the meat, not from the meat itself. Pasteur continued the experimentation regarding spontaneous generation in the 1800s with the growth of bacteria on soup.
The ancient belief that nonliving things could transformed into living organisms?
Spontaneous Generation
The experiment of redi and Pasteur helped to demonstrate that?
The experiments of Redi and Pasteur helped to demonstrate that all organisms come from other organisms. At the time, the prevailing theory was called "Spontaneous Generation" which assumed that organisms simply appeared. Both scientists delt with proving that, in the presence of oxygen, organisms did not grow if they were not exposed to microbe-containing air.
Is spontaneous generation the same as the current understanding of evolution?
No. Evolution explains how and why organisms change over time. It makes no difference to evolution how organisms are generated.
Non-living material can produce living organisms?
false... it is called spontaneous generation and has been proven to be wrong.
What does spontangeous generation?
Spontaneous generation is an old theory that organisms would be created without reproduction. (eg a mouse would be created by a bunch of mud in bucket).
What theory replaced the spontaneous generation?
The theory that replaced the theory of spontaneous generation is the theory of biogenesis. Biogenesis is the production of new living organisms or organelles.
