== Over-stated lead sentence ==
== ] studies worthy - or not? ==


I understand that this page is constantly subject to unscientific vandalism and distortion. However, to refer to "THE natural process by which life ARISES" is an inaccurate summary of scientific knowlege. We do not understand the chemical processes of abiogenesis or whether there can be only one such process, and we have no evidence that it occurred more than once. Perhaps it was inevitable and life exists on many planets, perhaps it was just very good luck and Earth is unique. It overstates our knowledge to say that life naturally arises.
Is the following edit (or related) worth adding to the main ] article?


To emphasize the uncertaintly about the chemical processes, I propose:
'''{{tq|Another strategy to understand abiogenesis may involve ]s in "bottom-up" (based on chemistries related to the prebiotic Earth) and "top-down" (based on chemistries related to current lifeforms) studies, according to biologists.<ref name="PNAS-20230814">{{cite journal |author=Goldman, Aaron D. |display-authors=et al. |title=Electron transport chains as a window into the earliest stages of evolution |url=https://www.pnas.org/doi/10.1073/pnas.2210924120 |date=14 August 2023 |journal=] |doi=10.1073/pnas.2210924120 |url-status=live |archiveurl=https://archive.ph/wip/5VD3s |archivedate=15 August 2023 |accessdate=15 August 2023 }}</ref>}}'''

== Quebec data ==


The last paragraph of the introduction of the article states in part "Fossil micro-organisms appear to have lived within hydrothermal vent precipitates dated 3.77 to 4.28 Gya from Quebec..." It seems to me that this statement is based on findings from one group of researchers, concerning the Nuvvuagittuq Greenstone Belt, that are not widely accepted. (In contrast to the data from Australia which are widely accepted.) If so, I would suggest that this statement about the findings in Canada could be changed to indicate that this is not widely agreed upon. For example, it could be changed to say "Some studies have suggested that fossil micro-organisms may have lived within hydrothermal vent precipitates dated 3.77 to 4.28 Gya from Quebec..." ] (]) 04:58, 9 June 2024 (UTC)
I'm not trying to help the creationist vandals of this article, but this article opens with a statement about how abiogenesis occured. Andndoes so as if the explanation given is a statement of fact and not just a statement of one of any different theories of abiogenesis. That's all I wanted to add. Even abiogensis is theoretical, but it's being treated as observed fact. ] (]) 17:30, 19 October 2023 (UTC)


:I agree; if it is not generally accepted then it should be qualified. ] (]) 05:45, 5 August 2024 (UTC)
:Have in mind that "theory" does not have the same meaning in everyday talk and in scientific talk. In science, Abiogenesis is accepted as a fact (even if we say that life started on Venus or Mars and then moved here by panspermia, it would have still started there, and the road from non-living to life would still be Abiogenesis). A theory in science is not a dubious fact, but an explanation of the precise way something happened. ] (]) 17:42, 19 October 2023 (UTC)

== "Habitable" Earth in top figure ==
:: Yes, it's a "theory" in the same sense as "theory of evolution", "cell theory of life", or for that matter "gene theory". There is no doubt among biologists that life works in these ways, however revisable all theories are in, er, theory. ] (]) 17:46, 19 October 2023 (UTC)
::OP is clearly using Theory in the sense of unproven but educated assumptions, not hard facts. The wording should be changed to reflect that it is theory. Criticisms of this theory include how entropy had to decrease a long way before biological processes would let it increase again. As well as how such complex genomes came to be so fast from nothing but free floating, individual bases. ] (]) 08:23, 16 November 2023 (UTC)


As this is a usual thing to clarify, I started the essay ], to define in a few words concepts like "theory", "hypothesis", "fact", "law", etc, how they relate to each other and the differences between each of them. The Misplaced Pages article is fine, but it may be a bit too complex for that, and the comparison of scientific ideas would be a bit out of place. ] (]) 19:52, 19 October 2023 (UTC) In the figure, the "habitable world" picture is today's earth, which has little in common with the habitable earth of 4.x billion years ago. I think it would be better to show a picture that plausibly depicts an initial habitable earth (which, of course, would be deadly to most current life).

== "Minimal requirements for life" unconnected to this article ==

An editor has inserted a chapter on this aspect of life, but Abiogenesis is a process, and the question of what life is defined as is no part of this article. ] (]) 22:05, 29 November 2023 (UTC)
:I searched for origin of life and this article popped up. The properties that would need to emerge of what would lead to life (e.g. capacity to metabolize energy or reproduction) is relevant no?] (]) 22:30, 29 November 2023 (UTC)
:: We do not construct articles based on editors' presumptions about what might be relevant to a subject (]), but on what authorities on that subject - scholars, scientists - have actually stated when describing the subject of the article. ] (]) 22:34, 29 November 2023 (UTC)
:::Well, origin of life textbooks like the Emergence of Life: From Chemical Origins to Synthetic Biology (Cambrdge Univerity Press) do talk about these things. For example, Oparin's model of molecules to macromolecules to metabolism, genetic code, and compartments to get to a cell. Also Origin of Life by David Deamer. ] (]) 22:44, 29 November 2023 (UTC)
:Actually, the definition of life does play a role in this. At the start of this whole process we have only unliving thing, and by the end of it we would have a living thing. The definition of life is important, because it would define the moment when we would cross that line. And that living thing that would emerge from this process would no doubt be different to the current living beings, so the definition should be a bit more flexible, to fit into that context. I have read this issue in books about abiogenesis, so yes, it's there.
:However, the proposed text does not do the job of explaining ''how'' the definition of life fits into all this, it merely lists some generic characteristics of life, so it does not add to the article as it was written. ] (]) 01:09, 30 November 2023 (UTC)
::Thanks for that. I suppose I could have reworded it to properties needed for transitioning from non-life to life or, put another way, possible criteria for prebiotic to biotic transitioning. Would that work? This is more specific to the article topic. Deamer says
::''"There is little agreement about a dictionary-style definition of life that can be stated in one sentence. The reason is that cells, the units of life, are not things, but instead are systems of molecular structures and processes, each of which is necessary for the function of the whole. However, it is possible to list the most general properties and then describe the individual structures and processes in such a way that when taken together they can only fit something that is alive. Maybe that's the best we can do, so here are some general properties followed by a list of twelve specific properties that define cellular life on Earth.''

::''General properties''

::''Living cells are encapsulated systems of polymers that use nutrients and energy from the environment to carry out the following functions:''

::''Enzyme-catalyzed metabolism''
::''Growth by catalyzed polymerization''
::''Guidance of growth by genetic information''
::''Reproduction of genetic information''
::''Division into daughter cells''
::''Mutation''
::''Evolution"''
::What do you think?] (]) 02:13, 30 November 2023 (UTC)
:::I think it's off the topic of the process of abiogenesis. This article, too, is not even limited to Earth, though it's obviously the example to hand. It doesn't matter for the process where along the line from nothing to obviously rampant evolving and flourishing where exactly is the "minimum" - whether 57.25%" or 61.39%, it's simply irrelevant here. ] (]) 05:55, 30 November 2023 (UTC)

== Need to filter over 20,000 bytes of student additions (and a pile of deletions) ==

A student has today inserted a large amount of material and cut a substantial amount of existing stuff, for a total change of +20,000 bytes or around 10%. Students are likely to be correct about recent facts and scientific papers; they are less likely to be right about balance, formatting, repetition, and the appropriate home for different sorts of information. This article is at the top of a tree of articles on origin of life topics, so it should only contain a brief summary of each subtopic; any sizeable additions should be scanned to identify what should remain up here and what should be hived off to new or existing "main" or "further" articles, many of which are already linked in the article. Any suitably informed and skilled help filtering the "new" material, and indeed checking that the deleted materials were appropriately removed, would be much appreciated. ] (]) 21:19, 8 December 2023 (UTC)

:I'd recommend reading new additions and then evaluating rather than making claims based solely on the quantitative amounts of added/deleted content. I can appreciate the need for an open encyclopedia to be succinct, but when this content contains points that are irrelevant to the main topics surrounding Abiogenesis, and bias the narrative, this is where contributions seem needed (regardless of the status of a "good article" being made). To address the material that needs to be 'filtered', this includes the main theories of a "Suitable Geological Environment", which now have the two main hypotheses in science today, (1) hydrothermal vents, and (2) surface bodies of water. Perhaps theories within these subcategories, including iron-sulfur world, zinc world, and clay could find a home in another more appropriate article.

Abiogenesis received a peer review by Misplaced Pages editors, which on February 2009 was archived. It may contain ideas you can use to improve this article.

? view · edit Frequently asked questions

Some users have noted that many of these questions should be included in the text of Abiogenesis. The reason for their exclusion is discussed below.

The main points of this FAQ (Talk:Abiogenesis#FAQ) can be summarized as:

  • The occurrence of abiogenesis is uncontroversial among scientists, and there is ongoing research and competing hypotheses for how abiogenesis could have occurred.
  • Misplaced Pages's neutral point of view policy requires that minority views not be given undue emphasis.
  • It is against Misplaced Pages policy for views without scientific support, such as all known objections to abiogenesis, to be included in a science article like Abiogenesis.

More detail is given on each of these points, and other common questions and objections, below.

To view the response to a question, click the link to the right of the question.

Q1: Why won't you add criticisms or objections to abiogenesis in the Abiogenesis article? A1: Our policies on Misplaced Pages, in particular WP:WEIGHT and WP:FRINGE, require us to provide coverage to views based on their prominence within reliable sources, and we must reflect the opinion of the scientific community as accurately as possible. While there are scientific objections to hypotheses concerning abiogenesis, general objections to the overall concept of abiogenesis are largely found outside of the scientific community, for example, in religious literature and is not necessary to hash out the evolution-vs.-creationism debate, per WP:NECESSARY. There are articles covering some of those religious views, including Objections to evolution, Creationism and Creation myth, but we cannot provide significant weight to religious opinions within a science article, per our policies. Further information: WP:Neutral point of view § Undue weight Q2: Why is abiogenesis described as though it's a fact? Isn't abiogenesis just a theory? A2: A "theory" in science is different than a "theory" in everyday usage. When scientists call something a theory, they are referring to a scientific theory, which is an explanation for a phenomenon based on a significant amount of data. Abiogenesis is a phenomenon scientists are trying to explain by developing scientific theories. While there isn't one unifying theory of abiogenesis, there are several principles and competing hypotheses for how abiogenesis could have occurred, which are detailed in the article. Misplaced Pages describes the phenomenon of abiogenesis as a fact because the reliable sources from the peer-reviewed scientific literature describe it as a fact.

Compare it with the theory of gravity, by Isaac Newton. It explains how gravity works, and it was superseded when Albert Einstein provided a more complete explanation. That doesn't mean that the factual existence of gravity was ever held in doubt.

See also: WP:Scientific consensus and WP:Scientific point of view Q3: But isn't abiogenesis unproven? A3: The scientific evidence is consistent with and supports an origin of life out of abiotic conditions. No chemical, biological or physical law has been discovered that would prevent life from emerging. Clearly, abiogenesis happened, because life exists. The other option is that life is a product of a supernatural process, but no evidence to support this has been published in reliable sources. There is plenty of evidence that nearly all the components of a simple cell can and do form naturally, but it has not yet been shown how molecules eventually formed self-replicating protocells and under what environmental conditions. Q4: Abiogenesis is controversial, so why won't you teach the controversy? A4: Abiogenesis is not controversial according to the reliable, published sources within the scientific community. Also, see Question 1.

Abiogenesis is, at best, only controversial in social areas like politics and religion. Indeed, numerous respectable scientific societies, such as the American Association for the Advancement of Science and the National Academy of Sciences, have issued statements denouncing creationism and/or ID. In 1987, only about 0.15% of American Earth and life scientists supported creationism.

Thus, as a consequence of Misplaced Pages's policies, it is necessary to treat abiogenesis as mainstream scientific consensus. Besides panspermia, there are no scientifically supported "alternatives" for this view. Q5: Has abiogenesis ever been observed? A5: No. How this happened is still conjectural, though no longer purely speculative. Q6: How could life arise by chance? A6: Based on the cited peer-reviewed scientific research, it is thought that once a self-replicating gene emerged as a product of natural chemical processes, life started and gradual evolution of complexity was made possible – in contrast to the sudden appearance of complexity that creationists claim to have been necessary at the beginning of life. Life did not happen just because there were huge intervals of time, but because a planet has a certain range of environments where pre-biotic chemistry took place. The actual nature of the first organisms and the exact pathways to the origin of life may be forever lost to science, but scientific research can at least help us understand what is possible. Past discussions

For further information, see the numerous past discussions on these topics in the archives of Talk:Abiogenesis:

The article is not neutral. It doesn't mention that abiogenesis is controversial.

The article should mention alternative views prominently, such as in a criticism section.

Abiogenesis is just a theory, not a fact.

There is scientific evidence against abiogenesis.

Over-stated lead sentence

I understand that this page is constantly subject to unscientific vandalism and distortion. However, to refer to "THE natural process by which life ARISES" is an inaccurate summary of scientific knowlege. We do not understand the chemical processes of abiogenesis or whether there can be only one such process, and we have no evidence that it occurred more than once. Perhaps it was inevitable and life exists on many planets, perhaps it was just very good luck and Earth is unique. It overstates our knowledge to say that life naturally arises.

To emphasize the uncertaintly about the chemical processes, I propose:

Abiogenesis is the a natural process by which life arises from non-living matter,

Or to emphasize the historical question of how it happened on Earth:

Abiogenesis is the natural process by which life arises arose from non-living matter,
It's not your or my place to temper what we feel to be an overreaching on the part of the reliable sources. To be frank, your revisions only introduce awkwardness to the prose borne from an apparent lack of engagement with said sources. Remsense ‥  14:11, 8 October 2024 (UTC)

Quebec data

The last paragraph of the introduction of the article states in part "Fossil micro-organisms appear to have lived within hydrothermal vent precipitates dated 3.77 to 4.28 Gya from Quebec..." It seems to me that this statement is based on findings from one group of researchers, concerning the Nuvvuagittuq Greenstone Belt, that are not widely accepted. (In contrast to the data from Australia which are widely accepted.) If so, I would suggest that this statement about the findings in Canada could be changed to indicate that this is not widely agreed upon. For example, it could be changed to say "Some studies have suggested that fossil micro-organisms may have lived within hydrothermal vent precipitates dated 3.77 to 4.28 Gya from Quebec..."

I agree; if it is not generally accepted then it should be qualified. Zaslav (talk) 05:45, 5 August 2024 (UTC)
do you have any sources that explicitly disagree with the Quebec data? Just because research is singular does not mean it is controversial. Remsense ‥  03:27, 7 October 2024 (UTC)

"Habitable" Earth in top figure

In the figure, the "habitable world" picture is today's earth, which has little in common with the habitable earth of 4.x billion years ago. I think it would be better to show a picture that plausibly depicts an initial habitable earth (which, of course, would be deadly to most current life). I'm not able to arrange this myself; sorry. Zaslav (talk) 03:49, 17 August 2024 (UTC)

The image is similar to the image in the research paper cited in the caption . Ramos1990 (talk) 04:11, 17 August 2024 (UTC)
The image is not meant to be "Earth when abiogenesis took place", but rather an "habitable planet" as a concept. Modern Earth gives the idea better than a hellfire ball would. Cambalachero (talk) 21:54, 17 August 2024 (UTC)
Very true. But I get the reason why it was brought up. Ramos1990 (talk) 10:20, 18 August 2024 (UTC)
