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.”

F/N: The notion that a mindless entity, the environment "designs" is a poor use of language; it is best to understand design as intelligently directed configuration. First, AmHD:
de·sign (d?-z?n?) v. de·signed, de·sign·ing, de·signs v.tr. 1. a. To conceive or fashion in the mind; invent: design a good excuse for not attending the conference. b. To formulate a plan for; devise: designed a marketing strategy for the new product. 2. To make a graphic or schematic representation of (something), especially as a plan for its structure: design a building on a computer; design a new car model. 3. To create or contrive for a particular purpose or effect: a game designed to appeal to all ages. 4. To have as a goal or purpose; intend: "Mrs. Bennet had designed to keep the two Netherfield gentlemen to supper; but ... she had no opportunity of detaining them" (Jane Austen). v.intr. 1. To make or execute plans. 2. To create designs. n. 1. a. A drawing or sketch. b. A graphic representation, especially a detailed plan for construction or manufacture. c. An ornamental pattern. See Synonyms at figure. 2. a. The purposeful or inventive arrangement of parts or details: the aerodynamic design of an automobile; the design of an epic poem. b. A particular plan or method: the party's design for increasing voter turnout. See Synonyms at plan. 3. The art or practice of designing or making designs: studied design in college. 4. a. A reasoned purpose; an intent: It was her design to set up practice on her own as soon as she was qualified. b. Deliberate intention: He became a photographer more by accident than by design. c. often designs A secretive or underhanded plot or scheme: He has designs on my job.

At best, the environment filters and limits what is possible by way of survival for creatures occupying certain niches. It limits, it does not actually cause new genetic information or the like. The onward problem is, that blind, chance variation is also not a particularly good source of fresh functionally specific information, and as for complexity beyond 500 -1,000 bits, not al all likely, given that FSCO/I depends on multiple, mutually fitting, well arranged, well organised and properly coupled parts to achieve function. The cellular metabolic network is a classic example, and shows the challenge to bridge an ocean of non functional configurations to get to the first island of function, the first living cell. [Genome likely 100 - 1,000+ k bases.] Similarly, the dozens of major body plans will require even more complexity [~10 - 100+ mn bases], bridging further spans of non function, to get to the commonly supposed well behaved functional space, the island of function. The deeply isolared protein fold domains are a good first case in point. In this context, the hypothetical -- guessed and now widely assumed -- "RNA world" [a modern myth dressed in a lab coat as so many are, Sci Fi/just so stories on steroids] would have to bridge to a world of cells using D/RNA,n with metabolic networks, with encapsulation and with smart gating. None of this is backed by actual observational substance. It is all speculation controlled by the imposition of Lewontin's cat out of the bag, a priori materialism. Ideology, backed by power institutions, especially those holding the cultural high ground for science, research, education and media dissemination. Mythology never stopped, it just put on a lab coat. So, in sum, design is not a capability of the environment and differential reproductive success, chance variation is highly limited and cannot account for information required to create body plans, and so ET has a point, there is no adequate actual theory of the [neo-] darwinist tree of life. Time to call in the myth busters. KFkairosfocus

So, the mindless environment designs, but a designer couldn't possibly be responsible for the design of the environment?

Fred Hickson:
Rapid climate change is threatening us now.
Rapid environmental destruction is threatening us. The climate now isn't much different than the climate 50 years ago. Greenhouse gasses affect the daily low temperatures because they only delay the onset of equilibrium. As of the end of May 2022, the "warming" was 0.17C above the arbitrary 0 line.ET

The environment designs by selecting variation that then proliferates
This is why Darwinian processes are extremely limited and thus confined to genetics only. Darwinian change is self refuting. Too much change because a variation is superior leads to entities that will destroy the ecology and eventually the species. So by definition, Darwinian processes cannot lead to major change. The best example is humans which are especially weak. This weakness causes issues with food generation. Yet after thousands of generations, no stronger humans to help with food production. But yet we have the eternally hopeful still pushing this illogical idea. So what else is new?
Rapid climate change is threatening us now
As it has since the beginning of time. But because of fossil fuels, humans are less susceptible to climate events than at any time in history. Deaths have declined 98% in last 100 years to adverse climate events because of the technology fueled by fossil fuels. Everyone should read Alex Epstein’s new book, “Fossil Future” to see the folly of the climate change alarmists.jerry

The environment doesn't design because it doesn't select. And most environments contain several varying designs. The only way the environment can design is if evolution proceeds via built-in responses to environmental cues, i.e., telic processes.ET

FH at 41, I'd like to point out that you imagine what an environment designs. I don't think you can prove that. And what if the environment changes too quickly for the organism to survive? Imagining a perfect environment is just imagination. And "selecting variation" implies intelligence which evolution does not have.relatd

On the UN-intelligent conveyor belt of life, totally unintelligent evolution just kept adding parts. You start with some amino acids – “the building blocks of life” – and keep (very randomly) building until you get to the RNA World model and keep adding parts until you get to DNA. Simple? Right?
Very wrong. RNA first. Then DNA. Then aminoacids. Then proteins. Possibly - at least conceivably.Fred Hickson

Some comments about communicating with people on the internet: Nobody actually knows anybody (aside from anyone you've met in real life). Imagine a meeting of educated people and total strangers can just walk in, unannounced, talk nonsense and leave. Or worse, continue to come back. Education levels can vary widely but how does anyone know that? Everyone is sitting in a black room and the only way to communicate with others around you is with a keyboard. Can this cause big problems communicating? Yes.relatd

Fred Hickson: Then you’d be pumping water uphill. The phrase is just shorthand for the second law of thermodynamics. I remember positing a 'perpetual motion machine' comprising of banks and banks of small tubes capitalising on the ability of capillary action to draw water up a tube without pressure to one of my university physics profs. He pointed out that if the system was closed the capillary action actually uses heat inherent in the system so, eventually, the capillary action would stop. Oh well. Physics, it's a heartbreak.JVL

Fred Hickson:
But RNA World is a feasible precursor.
Only in your little-bitty mind.
RNA sequences as both replicator and catalyst mean organisms with no need for code to link two separate systems.
There isn't any link between your fantasy and reality, Fred.
. DNA can also replace RNA as replicator without any codes as direct templating works as well between DNA and RNA as between RNA with itself
Pure stupidity! DNA is NOT a replicator! Without specialized, specific proteins to counter the instability of DNA, there isn't any DNA-based life! And those proteins have to be coded for in the DNA! The whole problem is Fred obviously doesn't like science and is ignorant of biology. He might understand biochemistry, but given that he thinks that DNA is a replicator, even that is doubtful. DNA is basically inert. It needs a suite of existing proteins and a specific coded information processing system or all it does is fall apart.ET

. But even as a no-code organism, if possible, a gradualist orgin of DNA code runs into the same problems Upright Biped has detailed and analyzed already.
I disagree. UBs argument about the arbitrary connection between DNA codons and aminoacide via aminoacyl tRNA synthetases is a fatal one IF there is no precursor. But RNA World is a feasible precursor. RNA sequences as both replicator and catalyst mean organisms with no need for code to link two separate systems. DNA can also replace RNA as replicator without any codes as direct templating works as well between DNA and RNA as between RNA with itself. Codes, perhaps starting with four codons: AXX, CXX, GXX, TXX and a more promiscuous and limited initial number of aminoacids (why not one?) can then be added to by evolutionary processes and the role of RNA similarly reducing.Fred Hickson

Fred ==Have you noticed water running uphill?== You can get it to run uphill if you apply pressure. Are you saying that configurations like your own comment in this thread when displayed on the monitor, a microchip or an integral scheme of a radio receiver are reducible to the laws of nature? Really? Have you heard about the initial/boundary conditions? Do you know what sort of boundary conditions are necessary for a self-reproducing semantially closed system with memory? Do you know what code is and why it is necessary for such systems to exist?EugeneS

Ribozymes still face the sequence specificity obstacle. Not any RNA sequence produces a ribozyme. The longer the sequence the shorter the odds of nature producing it. It is very likely that any RNA world is physically impossible without intelligent agency intervention. The smallest ribozyme is 5 nucleotides but has a minimal skill set. Even if we grant that nature could produce it, that really isn't saying anything because of that very limited ability. Just by looking at how much intelligent agency intervention is required for the meager results pertaining to RNA should give you a huge clue into the unbreachable obstacle for materialistic processes to pull off.ET
