"evilution"?!
That doesn't sound like you!
Sorry for the typo, but yes many fundamentalist Christians consider evolution evilution.

Yes the hypothesis is abiogenesis, and yes you misused the terminology of hypothesis and evidence in your previous confusing post.
Very very confusing response. You have not made yourself clear on your objections to abiogenesis. Actually the boundary between evolution and abiogenesis is not clear, and many of the concepts of organic evolution of life apply to the chemical evolution of the pre-life forms in abiogenesis. Viruses and their primitive forms are a classic examples which would be transitional from pre-life chemical beginnings to living organisms
I notice that you acknowledge as bolded that the research does 'provide evidence' for abiogenesis, as do the hundreds articles you can read simply going a google search.
Yes, and homo sapien, interbred with homo neanderthalensis, as that population ( H. Neander) declined due to our induced competitive exclusion.
Not evidence. Its hypothesis based on experimentation that proposes a final possibility of a replicator.
The evidence for the hypothesis was cited. It is descriptive based on the avialable evidence like all science.
And the DNA of the Neanderthanls and Denisovans is still with us In fact, I am 2.4% Neanderthal and 2.5% Denisovan, according to my DNA results from the National Geographic "Genographic" study.
“Foot-powered whales”?
Couldn’t seem to find any articles discussing them. (They were only mentioned — never discussed — in those articles about Aegicetus gehennae.)

What's the evidence?
The most abundant organic matters in the human body are cells, all different types of cells.
But in term of biological molecules and about 20% of the mass these are proteins, followed by 12% being lipids (fat).
The nucleic acids, RNA only make up about 1% of our mass while DNA 0.1%.
About 60% to 65% of our mass is water, but water is inorganic molecules.
What is essential to every cells, not just cells in humans, but in all living organisms, there are 3 biological macromolecules (large molecules) are found in common:
Since proteins make up large part of the body mass of most living organisms, so they have broken down proteins and found that proteins are made of another biological compounds - amino acids.
- proteins,
- nucleic acids,
- carbohydrates
There are over 500 different types of amino acids, but only 23 different types can be found in proteins - hence these are labelled as “proteinogenic amino acid”.
Hence, scientists have tried to mimic Earth’s early environments of possible known inorganic chemicals in the air (atmosphere) and water, to produce amino acids from various inorganic compounds.
And in Earth’s early atmosphere, there wouldn’t be any free oxygen at that time, so any experiments must be preformed in oxygen-free environment.
In the Miller-Urey experiment in 1952, they used water, methane, ammonia and hydrogen. They have also use heat and electricity (electrodes, to mimic the lightning) to start the catalyst of chemical reactions.
In the aftermath of the experiment, 11 amino acids were detected, then stored away in 20 sealed vials until after Miller’s death in 2007. The vials reveal another 9 different types of amino acids have formed over time.
Other chemicals were added in different experiments by other scientists, also to mimic Earth’s early atmosphere, such as nitrogen, frequent volcanic activities around that time would have produced inorganic gases such as carbon dioxide, hydrogen sulfide and sulfur dioxide. They yield some successes in different experiments.
In 1961, Joan Oro did experiment in which he produce adenine which form the basis of nucleobase, which is a component of nucleic acids. Oro did so with only 3 chemicals.
So to answer your questions, yes there are inorganic chemicals can result in chemical reactions that form specific biological/organic compounds.
@gnostic listed experiments that showed the formation of organic chemicals in a simulated early earth atmosphere. If that isn't evidence for you, what is?I truly appreciate your effort and knowledge. What I asked for is evidence for abiogenesis, not the hypothesis.

(And remember that we'll hold your evidence for your hypothesis to the same standard.)
Abiogenesis is a hypothesis. It isn’t a scientific theory, and it is science yet...I truly appreciate your effort and knowledge. What I asked for is evidence for abiogenesis, not the hypothesis.
