Why are maggots not jar?
Answer. Answer: To test the hypothesis, Francesco Redi placed fresh meat in open containers [left]: as expected, the rotting meat attracted flies, and the meat was soon swarming with maggots, which hatched into flies. When the jars were covered so that flies could not get in [middle], no maggots were produced.

Redi’s hypothesis suggests that flies lay eggs that produce maggots, thus refuting the theory of spontaneous generation.
What was Redi’s theory called?
spontaneous generation
Who discovered the fly?
The Wright brothers
Who discovered maggots?
Francesco Redi
How did Pasteur’s experiment disprove spontaneous generation?
To disprove the theory of spontaneous generation, Louis Pasteur devised a way to flask that allowed oxygen in, but prevented dust from entering. The broth did not show signs of life until he broke off the neck of the flask allowing dust, and therefore microbes, to enter.
Why did the law of spontaneous generation survive for so many years?
Why did the law of spontaneous generation survive for so many years? It survived because flawed experiments seemed to confirm it.
What was the variable in Pasteur’s experiment?
Pasteur then observed the response of the dependent variable (the growth of microorganisms) in response to the independent variable (the design of the flask).
Who proved the spontaneous generation wrong?
Prominent scientists designed experiments and argued both in support of (John Needham) and against (Lazzaro Spallanzani) spontaneous generation. Louis Pasteur is credited with conclusively disproving the theory of spontaneous generation with his famous swan-neck flask experiment.
Why is the idea of spontaneous generation incorrect?
It was once believed that life could come from nonliving things, such as mice from corn, flies from bovine manure, maggots from rotting meat, and fish from the mud of previously dry lakes. Spontaneous generation is the incorrect hypothesis that nonliving things are capable of producing life.
Why is spontaneous generation False?
For several centuries it was believed that living organisms could spontaneously come from nonliving matter. This idea, known as spontaneous generation, is now known to be false. Spontaneous generation was disproved through the performance of several significant scientific experiments.
Why did anaximander decide that humans descended from fish more than 2000 years ago?
Anaximander looked at the life around him and came to the conclusion that it must have evolved from other lifeforms. Anaximander speculated that our ancestor may have been a fish-like creature which gave birth to humans when they had reached an age when they could survive without parents to look after them.
What question is anaximander trying to answer?
The three first philosophers from Miletus were Thales, Anaximander and Anaximines, all of whom attempted to answer the question “What is the common stuff from which everything is composed?” The details of Thales’ philosophy are as sketchy as those of his life.
What is the idea of Pythagoras?
