Observations such as the presence of organic molecules in primitive Earth conditions, experiments showing the formation of organic molecules in simulated prebiotic environments, and the discovery of extremophiles that can thrive in harsh conditions have contributed to the theory of abiogenesis, suggesting that life could have arisen from non-living matter through natural processes.
The observation of microorganisms appearing spontaneously in broth that was thought to be sterile led to the theory of abiogenesis, the idea that life can arise from non-living matter under certain conditions. This was later disproved by Louis Pasteur's experiments, which showed that life only comes from preexisting life.
Abiogenesis is the scientific theory that life can arise from non-living matter, while biogenesis is the theory that living organisms can only come from other living organisms. Abiogenesis is concerned with how life originated on Earth, while biogenesis explains the reproduction and growth of living organisms.
The abiotic origin of life is referred to as abiogenesis. It is the scientific theory that life can arise from non-living matter through natural processes.
Louis Pasteur is often credited with disproving the theory of abiogenesis through his experiments in the mid-19th century. He showed that life only arises from pre-existing life, contradicting the idea that living organisms could arise spontaneously from non-living matter.
Biogenesis? You mean, abiogenesis? There is no theory of abiogenesis yet. Some people have done spurious calculations using information theory. I consider these efforts a problem, in that they detract from serious consideration of abiogenesis. The problem is that cells are hideously complex, and the gulf between self replicating cells and amino acids (which form naturally in a wide range of environments) is very large. One hypothesis for bridging this gap is known as the RNA world hypothesis, but there is as yet no decent general theory of abiogenesis.

yes, recent observations have led to a possible bar-spiral theory
Few still believe in the theory of abiogenesis as it was proposed by aristotle. Evolutionary chemists who study how primordial life may have started technically study abiogenesis. The transformation from chemical soup to primitive RNA strands or protein strands to viruses/prions to other microbes can be considered abiogenesis.
Scientists used microscopes to gather observations that led to the formation of the cell theory. These observations allowed scientists to see and study cells, leading to the discovery of their structure and function.
Abiogenesis.
This is the theory of abiogenesis - the theory that life can spring fully formed from non-life.
The observation of microorganisms appearing spontaneously in broth that was thought to be sterile led to the theory of abiogenesis, the idea that life can arise from non-living matter under certain conditions. This was later disproved by Louis Pasteur's experiments, which showed that life only comes from preexisting life.
If new observations are discovered that clash with the previous theory, then the theory will have to be revised.
Abiogenesis refers to the hypothetical organic phenomenon by which a given living organism are created from the living matter. An example in a sentence includes "The first step in the scientific refutation of the theory of abiogenesis was taken by the Italian Redi."
