Ancient, Egyptians, and Aristotle
58
Proposes that the conditions prevailing on earth, life arose from a series of chemical conditions or reactions

they didn't prove anything and it was just a story
ALEXANDER OPARIN AND HALDANE
58
WHO DID THIS
heat the gravy, I will cover it, even if it is covered, an organism will come out
There are possibilities that has been missing in this experiment
the fire is weak so the microorganisms present in the gravy or soup are not completely killed so some are still alive
JOHN NEEDHAM
59
They did the theory of Oparin and Haldane
From a non living thing, they used an array or an experiment. With this, they were able to create life.
They used an activator which is lightning. When energy was released, it evolved.
This somehow supports the claim of abiogenesis theory
Harold Urey and Stanley Miller Experiment
60
Experimented with fruit flies
He set up 3 jars with meat: opened, tightly sealed, and covered.
He demonstrated that dead maggots or flies would not generate new flies when placed on rotting meat in a sealed jar, whereas live maggots or flies would.
Francesco Redi
60
Life coming from life
BIOGENESIS
61
Experimented with gravy
Boiled the gravy: open and closed
Open: has microorganisms
Closed: no microorganisms
The stronger the fire, the longer he heated it, so the microorganisms died, and when he opened it, there were microorganisms.
He showed that it is not an inherent feature of matter and that it can be destroyed by an hour of boiling
Lazzaro Spallanzi
62
Father of Pasteurization process
He debunked the theory of abiogenesis
He used a u-shaped. He heated it and opened it.
when he saw, those inside had no organisms because of the distance they had traveled. organisms lived in a u-shape. when he destroyed it was spoiled. The microorganisms have come out of it because they could easily enter.
