Dust from an asteroid collected by a Japanese space probe contains clues to the origin of life, suggesting it was formed in space, scientists reported Friday.

Japan’s Hayabusa2 space mission dropped samples from the asteroid Ryugu to Earth in the Australian outback in December 2020. It was then moved to Japan to be studied for insights into the origins of the solar system and life on Earth.

Scientists most recently announced the finding included nearly two dozen types of amino acids in the sample, the Japan Aerospace Exploration Agency (JAXA ) said.

Finding amino acids is a big deal, because they make proteins and are necessary to support life. This is also the first time they’ve been found on an asteroid, the Japan Times reported.

USA Today

In considering the significance of this report, it is important to realize that finding naturally occurring amino acids does not amount to showing how life could form naturally. As discussed in my book, Canceled Science, “Amino acids, such as can sometimes form naturally, do not remotely approach the molecular complexity of even the simplest living cell. Believing otherwise is like finding a few brick-shaped rocks up on a hillside and concluding from this that buildings and whole cities arose by nothing more than the same blind forces that formed those rocks.”

No one has shown that any RNA world is possible. No one has shown it is feasible.
The distinction between living and non-living is (definitely in this forum) a semantic one.
It doesn't get much dumber than that, folks. Biologists don't know what they are supposed to be studying! But that is moot as Fred won't even try to support that claim.ET

FH at 24, You seem to think that living things need just a little push for them to "go up that hill" leading to more complexity. The carved in stone rules regarding chemistry combined with wishful thinking cannot result in something you want to happen.relatd

FH at 22, The story for evolution requires earlier forms that get more complex. The RNA World is hypothetical - it's not real. But, according to scientific imagination, there must have been something before DNA so RNA is chosen and before that, strings of amino acids. So, it fits the storytelling template. Evolution, blind and unguided, can do anything. And it's always upgrading - for no particular reason. I don't think you speak for scientists when you make the claim that RNA World is physically possible. I think you would like it to be. You appear to be fixated on chemistry and chemical reactions but there's no evidence that complexity generated itself.relatd

FH at 20, No Fred. Living means alive. If you think you're just an ambulatory bag of chemicals then you are indeed missing the point. You were designed. Plants and animals were designed. Your computer could be broken down to a list of chemicals but it was also designed. Scientists have looked at the rules governing the observable universe. If some rules were off by some small fraction, certain things would be prohibited from occurring, including life. You appear to think that rules governing chemical reactions could somehow lead to living things, but at the cellular level, we're talking about organic machinery that has built-in function and that can interact effectively with the world around it. Design, not blind, unguided chance.relatd

Don’t you know? It’s all chemicals. Given enough time – chemicals can upgrade from dead to living.

Fred ==So, given enough time,== No matter how many times to repeat it, it does not become true. Where have I heard this? Oh yes, monkeys and typewriters. Do you realize that the theorem with the funny name of 'infinite monkeys' is not your ally, it is your enemy, because this universe had a beginning and it is very young for this sort of thing. Even the most liberal estimates of its age are critically not enough for anything like you say to even remotely look like plausible. Even the text of your comment took intelligence to appear. And here you are suggesting that it all happened by itself, given enough time. It amazes me how this old trick can work time after time... There has not been enough time.EugeneS

Mandatory codes- the genetic code is mandatory for all living organisms on Earth. There are more such codes listed on Code Biology. I know about the emergent properties of RNA, Fred. I understand the bonds between bases, Fred. None of that helps you get any RNA world. Joyce and Lincoln had to design the RNA's in their "self-sustained replication of RNAs". No one has ever observed such RNAs develop without intelligent agency volition. And Spiegelman's Monster is a problem for any alleged RNA to anyone who understands it. It demonstrates that nature tends towards the more simple. However, the problem remains the same. Nature can't even produce catalytic RNAs of 48, 54 or 218 bases. So, Fred, again, all you have is your fantasy world of imagination and avoiding the evidence and reality.ET

FH at 14, The precursor followed by the precursor and then the precursor. DNA > RNA > strings of this and that > dead chemicals. Or we can't have so-called "modern" humans without precursors like Neanderthals or Denosovians. But it turns out that so-called modern humans have DNA from both.relatd

FH at 10, So, given enough time, we get "electropositive hydrogen acceptors and electronegative donors"? Based on what? Aside from imagination. "inherent spacial arrangement"? Sounds like dead/inorganic chemicals 'accidentally' becoming alive.relatd

Relatd and ET I would be more impressed if you knew more about the emergent properties of RNA and pair bonding between purines and pyrimidines due to the inherent spacial arrangement between electropositive hydrogen acceptors and electronegative donors. Also the pivotal role that RNA still plays in the metabolism of all living organisms we know of. This is not made up.Fred Hickson

Learn how to read, Fred: "The RNA world is a hypothetical stage...". I know that I have mentioned that, already. And the circumstantial evidence is all imaginary, too. You look at the way things work in modern cells and try to extrapolate that into "nature did it". That RNA was intelligently designed to be a catalyst and an information carrier, in no way supports your imaginary scenario. No codes needed. No evidence needed, either. And no way to even test the claim. Then there is Spiegelman's Monster. And I know why you would want to avoid that. There isn't any connection from your "no codes needed" fantasy world to several codes mandatory real-life scenario. All you have is blind faith.ET

FH at 7, I work with professional storytellers. We produce plausible fiction. If the idea of an RNA world crossed my desk, I'd toss it because it represents wishful thinking. It's not good storytelling, it's "I wish this were true." And your evidence amounts to "and then it turned into DNA." That's not evidence. That's wishful thinking.relatd

This RNA World, ET. I think I may have mentioned it already. A hypothesis without direct historical evidence but plenty of circumstantial evidence, especially the emergent properties of RNA which are available to all to verify. No codes needed either.Fred Hickson

Interesting! This is new and adds evidence to the idea that the transition to DNA/RNA/protein world from RNA world could have relied on protein scaffolding. https://www.tandfonline.com/doi/full/10.1080/15476286.2020.1801199 Whilst considering RNA world and panspermia as alternative paths to life on Earth, I never considered it could be both! :) H/T BobFred Hickson
