Really and what kind of resoult in experiments would falsify abiogenesis?
You really are behind time with news about Abiogenesis.
And you still don’t understand what the word falsifiability
Some experiments have already been done with Abiogenesis, so Abiogenesis is already a falsifiable hypothesis.
And it is a hypothesis that they are still testing, hence it is work-in-progress falsifiable model.
Different experiments have been done for decades, since the earliest experiment in 1952 the Miller-Urey experiment.
We already know that the earliest organisms were bacteria in which some species can exist without oxygen in the early atmosphere.
But Abiogenesis isn’t just a model about creating life; it is also about creating organic matters from inorganic matters, through chemical reactions. Organic matters, like biological molecules, like proteins, nucleic acids and carbohydrates.
These molecules or compounds are present in all cells, tissues and muscles. Life cannot exist until these biological compounds formed first in the earliest cells.
Proteins are made out of amino acids. There are over 500 different types of amino acids, but only 23 types exist in different types of proteins.
In the Miller-Urey experiment, they used inorganic compounds, like water (H
2O), ammonia (NH
3), methane (CH
4) and hydrogen gas (H
2), and used heat and electric spark to mimic lightning strike that would start off chemical reactions in these inorganic chemicals.
The chemicals used were to mimic Earth’s early environment, including atmosphere with no free oxygen gas, hence pre-biotic environments.
The end results of this experiment, 11 amino acids were formed.
Instead of throwing away these test results they stored them away in sealed vials, and didn’t look at them until Stanley Miller died in 2007.
Upon examination of these vials 9 more amino acids have formed during storage, bringing a total of 20 of 23 proteinogenic amino acids.
Stanley Miller’s student, Jeffrey Bada, also performed a similar experiment. But added nitrogen gas (N
2) and carbon dioxide (CO
2) that would have be present in early Earth pre-biotic atmosphere, as well as iron and carbonate minerals that would exist on Earth’s crust, to produce amino acids.
The 1961 experiment by Joan Oró, managed to create adenine, which is biological part of nucleobase, and nucleobase is one of the important components in nucleic acids (nucleic acids, eg RNA & DNA). Adenine was chemically formed from inorganic compounds hydrogen cyanide (HCN) with ammonia and water.
Then there is amino acid evidence discovered in some large pieces of meteorite that crashed near the town of Murchison, Victoria, Australia in 1969. Over 100 amino acids, of which 19 were proteinogenic.
And amino acids weren’t the only organic compounds found in this meteorite. There were also hydrocarbon (oils), carboxylic acids and more.
The indication that organic matters can exist space, on meteorites, asteroids or comets, provide a different probability that the source to life on Earth, may have been kickstarted when these objects crashed on young Earth about 4 billion years ago.
There are at least 3 different models (versions) to Abiogenesis that I know of, being investigated by biochemists, including the extraterrestrial source. The others are pond scenario and hydrothermal vent scenario.
All 3 models of Abiogenesis are falsifiable, but they don’t know (yet), which of these are most likely model that started life on Earth.
I am not a biochemist or biologist, but even I can understand that before cells can exist, these biological molecules must exist first, so that’s why they are starting experiments to create biological molecules from inorganic chemicals, to mimic Earth’s early conditions before there oxygen in the atmosphere.
Please learn what falsifiable actually mean, because you still making the same mistakes repeatedly since you had joined RF. Stubborn ignorance isn’t a virtue.
