Is there any way to replicate the process of how organisms formed in the oceans in Earth's early life? I think I've seen an experiment like this, don't remember the name.

[Anonymous No.5014192]

That would be the Miller-Urey experiment. Good shit

[Anonymous No.5014201]

>>5014192

thank you sir

[Anonymous No.5014592]

Miller-Urey didn't show anything about organisms forming, or even very complex biomolecules.
It just showed that some important precursor molecules could be formed under natural circumstances in an early earthlike environment

>replicate
>Earth

OP stop assuming, please.

Also can you please clarify whether you mean an experiment on protein or catalytic RNA

I'm fairly certain Eugene Koonin writes and publishes a shitload of papers ever year on such topics.

I had to read one for my evolution class that proposed a mechanism of early life diversification. You might like it, if you're into the more technical aspects.

But I would definitely have to say that I'm 90% certain that Eugene Koonin is a scientist who is currently heavily involved in the field, and any new information you are going to read about will probably have his name on it, if not attached to the title, then attached to the citations.

As an addendum, last I knew (which was 2-3 years ago when I took my evolution class) most of his stuff is in the more in the predicting stage. The testing of the predictions has yet to occur, but there is some decent evidence that that's a viable idea.

>some important precursor molecules

All 20 amino acids formed.

[Anonymous No.5014710]

>>5014682
RNA everywhere

to say amino acid based life was first is like saying leaches lived before blood.

[Anonymous No.5014731]

>>5014710
You can't have RNA without amino acids. This isn't a chicken and egg problem.

[Anonymous No.5014777]

I thought it was pretty much established that life came to Earth from Mars via meteorites and shit. No such thing as formed of pan spermia

OP I'm sorry but nobody knows how life really started on this earth. We have an idea of what conditions might have been necessary but we don't really know exactly what or where started the first cell. Probably a lot of trial and error over millions of years.
>>5014192
But yes this is the experiment you're thinking of, and it deals mainly with amino acids or some shit.

And this would suck because we can't replicate it.

[Anonymous No.5014984]

Whether or not it was actually the route taken, the RNA World hypothesis is a good demonstration that at least one route from non-life COULD have happened on Earth.

We know the precursors to RNA existed, we know that RNA could have spontaneously combined, and we know that certain pairs of RNA molecules can cooperatively catalyze each others' construction in an error-prone way.

Given those factors, the proposition that RNA could have evolved into loosely organized collections of RNA molecules, and from there lead to the creation of DNA as a more stable storage form of RNA, is plausible.

yup - and structural RNA still found in everyone's ribosomes

Isnt it funny how these atheists disregard science and get all hyped up with their own beliefs and actually believe silly concepts like amino acids coming together is what started life?
