what is spontanius generation?

Question

biology

Answer 1

Spontaneous generation is the notion that life can instantaneously arise from non living objects, a conjecture that was proven false hundreds of years ago. However, it is not hard to understand why many people, in the days before modern science, would believe in such a concept. Keep a pile of dirty laundry out, and eventually it will be swarming with rats. Leave a piece of meat in the sun, and soon maggots will cover it. Thus, it was assumed that the laundry and the meat created these entities.

A very well known experiment in the 1600s, by the italian scientist
Francesco Redi, began to disprove spontaneous generation. He put three pieces of meat in three jars. One jar was tightly sealed, another was left open, and the third was covered with netting. He discovered that maggots appeared on the open jar, but not on the closed ones. He then continued, placing live flies in sealed jars with the meat, and showed that maggots appeared under these circumstances. This was good evidence that it was not the meat itself generating the maggots, but instead the adult flies.

Answer 2

centuries ago, scientists debated about the origin of life. aristotle proposed that life came from 'spontaneous generation' - life came from nothing. this became a sort of universal truth then. an example of a 'proof' of spontaneous generation would be this: put a piece of meat in an open container. one week later, there will be maggots. where did the maggots come from? according to spontaneous generation, the maggots came from nothing.
however, this theory is fallacious, and was eventually disproved by the likes of louis pasteur.

Answer 3

it is the theory that living things can arise from nonliving things like flies arise from decaying meat
