The lab leak hypothesis means "accelerated evolution" through either caged animals or "in vitro cells" infecting the lab personnel. Gene splicing and such are not necessary to make the argument.
The observed fact pointing to this is the number of generations required to produce the divergence between the first SCoV2 variant and the closest wild ancestor. It corresponds to something like 20 years (?) of evolution.
"...zoonosis (a disease communicable from animals to man under natural conditions)." —Laurie Garrett, _The Coming Plague_ (Ch 14, section IV)
Which is naturally how the word is used virtually all the time.
Transmission from lab animals kept for study in a biolab, you could argue either way. Transmission from humanized lab animals purposely subjected to serial passage is not really zoonosis in any reasonable sense.
What's notable about the SCov2 variant is how well it spreads between humans. It probably has made the jump many times, it's just this time it figured out how to spread.

Even if it leaked from the lab, the first affected people (mainly sellers) were from the market, which is weird. Occam's razor points to what you said.
I guess everyone loves a good conspirancy.
You're just repeating the conclusions of papers that made ridiculous leaps of logic based on circumstantial evidence. For example [1], which is the likely source of the argument you're (mis-)remembering, bases this conclusion on:
1) case histories from reported, hospitalized cases, which were probably incorrect (i.e. they just assume that the cases they know about are, in fact, the first cases), being "geographically centered" on the market in December (not November) of 2019 [2].
2) positive environmental samples near animal stalls in the market, of which they found two strains.
Neither of which is dispositive of anything, and more an indictment of the motivated reasoning of the academic literature at the time than anything else. If you bother to read any of the subsequent analyses, you'll find that there are a bunch of different lines of evidence (genetic and case reports, at the least), pushing the date of the first infections well before December.
In short, the first/WHO case reports were probably wrong, the virus likely broke out earlier and was circulating in Wuhan before these samples were taken. If that's true, it wouldn't be surprising, at all, to find positive environmental samples in a food market, and the tortured logic of this paper would fall apart.
[1] https://www.science.org/doi/10.1126/science.abp8715
[2] Seriously. Not joking. Here's the "methods" they used for this oh-so-rigorous analysis:
> The 2021 WHO mission report identified 174 COVID-19 cases in Hubei Province in December 2019 after careful examination of reported case histories (7). Although geographical coordinates of the residential locations of the 164 cases who lived within Wuhan were unavailable, we were able to reliably extract the latitude and longitude coordinates of 155 cases from maps in the report
They then take this data and blend it through a kernel analysis, wave their hands, and voilá! This this The Science (tm) upon which your confidence is based.
...oh, and by the way: the market in question just happens to be right next to the Wuhan CDC, and a major city hospital [3]. Weird, right? I'm sure it's just a coincidence. Certainly nothing worth including in a putative "probability analysis" of geographic distribution.

If the disease had already been global, then retrospective testing of wastewater samples, nasal swabs obtained for other purposes like the Seattle Flu Study, banked blood, and other stored samples would have revealed that. There were some scattered claims that it did, but none that held up very well under scrutiny.
There are studies pre SARS-CoV-2 about coronavirus in natural environments (like bat caves), and they found motifs that we found also in SARS-CoV-2. Zoonotic infections are very common and specially for coronavirus, so it should be our first guess unless overwhelming evidence shows that the virus was originated in a lab (leaked or engineered).
Maybe it was a lab leak, but there is not stronger evidence for that, than for the zoonotic event.
Here is your bad science:
- H0: The origin is the lab.
- H1: The origin is a naturally ocurring zoonosis.
As evidence for H1 cannot convince you, you accept H0 without any proof. Great science! Problem is your H0 is wrong. H0 should be the most easy explanation, which is a zoonosis that has happened before thousands of times, and for which we have also evidence (you call it circumstancial, as this was a trial) like similar sequences found in bats nearby. You must get better evidence to prove the unusual lab leak hypothesis. Your H0 and H1 are reversed.
> There are studies pre SARS-CoV-2 about coronavirus in natural environments (like bat caves), and they found motifs that we found also in SARS-CoV-2.
You're doing it again here, but I think you're probably referring to Andersen's Proximal Origin:
https://www.nature.com/articles/s41591-020-0820-9
But nobody disputes that SARS-CoV-2 evolved mostly in bats; the question is whether its path from bats to humans included a trip through the lab. No genomic evidence can distinguish between a novel natural virus and a chimera of two novel natural viruses. As Davis Relman wrote:
> Some [that's Andersen] have argued that a deliberate engineering scenario is unlikely because one would not have had the insight a priori to design the current pandemic virus. This argument fails to acknowledge the possibility that two or more as yet undisclosed ancestors i.e., more proximal ancestors than RaTG13 and RmYN02) had already been discovered and were being studied in a laboratory—for example, one with the SARS-CoV-2 backbone and spike protein receptor binding domain, and the other with the SARS-CoV-2 polybasic furin cleavage site. It would have been a logical next step to wonder about the properties of a recombinant virus and then create it in the laboratory
https://www.pnas.org/doi/pdf/10.1073/pnas.2021133117
The WIV had the biggest collection of novel sarbecoviruses in the world.
As for the rest of your comment -- oy, talk about a straw man fallacy. There's absolutely nothing I said that requires the false dichotomy you've presented between H0 and H1 (i.e. there are other plausible hypotheses that aren't as extreme as the ones you've presented). Also, I don't "accept" H0. I just can't rule it out.
> H0 should be the most easy explanation, which is a zoonosis that has happened before thousands of times, and for which we have also evidence
Neither hypothesis is easy (i.e. likely). Natural, human-optimized zoonosis is incredibly rare in viruses. Making humanized viruses in a lab, starting from natural viruses, is actually straightforward. But when one of the world centers for doing that kind of work, on very similar coronaviruses, was right there in Wuhan...
https://www.cell.com/cell/pdf/S0092-8674(24)00901-2.pdf
It found that viral RNA and DNA from potential zoonotic hosts (palm civets, raccoon dogs) occurred together in some samples from the Huanan Seafood Market. But there's no question that infected humans were present there, and nothing in their study can distinguish an infected palm civet from a healthy palm civet near an infected human.
A different study by Jesse Bloom found that of all the animals present, viral RNA correlated most strongly with DNA from "catfish and largemouth bass":
https://academic.oup.com/ve/article/9/2/vead050/7249794
So were those the proximal hosts? Obviously not, since SARS-CoV-2 can't infect fish--the point is that this is all just noise. Live, unquestionably infected proximal hosts were found for both SARS-1 and MERS, within about a year of the first human cases. For SARS-CoV-2, we still have nothing beyond those tortured metagenomics.
Civets at the very least are known to be the host for SARS-CoV virus that jumped to humans. The first affected people all had in common the market, and not the lab. Samples from the market in early 2020 found a lot of SARS-CoV-2 everywhere, specially at stalls that were selling poultry and racoons. The market was stuffed with animals. As poor as the security was in the lab, the market was orders of magnitude worse.
I might be wrong but I swear I read they never found cov 2 in an animal that could transmit to humans
And of course the Chinese government restricts access--there's no way to prove a negative, thus no way to exonerate them. No matter what investigators are allowed to see there will always be the allegation that they aren't being allowed to see the important stuff.
But I see no reason to suspect a leak from the hot part of the lab. While it's not impossible I see no non-political reason to think it did happen.
It's obviously false if you just think about it, but you can also do some searching if you need some authority to tell you.
I would not trust any of these agencies to provide objective findings or conclusions, there is a lot of power on the table that's at stake.
The intelligence networks there were weak, and if people were talking about it, they may have assumed wrongly that there was something there.
Politicians hunting for excuses to do what they already want to do though, is definitely a thing.
Just to be clear: The people in charge are the CIA, not GWB. GWB was simply the right useful idiot at the right time in the right place.
I don’t know where you are getting your information from but it’s absolutely incorrect.
It was Cheney specifically who was relying on Chalabi whom the CIA had repeatedly dismissed as a fabricator which is what was used as evidence.
There were a lot of indications that it was wrong even at the time, like the inspectors’ reports. We knew about the unreliability of the dodgy dossier and how baseless Khidir Hamza was. The satellite evidence was sketchy and the rest was contradictory. Al-Qaeda was also not there and we also knew that. Let’s not rewrite history: there is no certainty in intelligence, but anyone not in the CIA’s pocket knew it was most likely wrong, a far cry from what you need to legitimately attack a country.
HANNITY: So he had them.
SADA: Yes.
HANNITY: Where were they? And were they moved and where?
SADA: Well, up to the year 2002, 2002, in summer, they were in Iraq. And after that, when Saddam realized that the inspectors are coming on the first of November and the Americans are coming, so he took the advantage of a natural disaster happened in Syria, a dam was broken. So he — he announced to the world that he is going to make an air bridge...
HANNITY: You know for a fact he moved these weapons to Syria?
SADA: Yes.
HANNITY: How do you know that?
SADA: I know it because I have got the captains of the Iraqi airway that were my friends, and they told me these weapons of mass destruction had been moved to Syria.
BECKEL: How did he move them, general? How were they moved?
SADA: They were moved by air and by ground, 56 sorties by jumbo, 747, and 27 were moved, after they were converted to cargo aircraft, they were moved to Syria.
We went into Iraq because the White House latched on to insufficient and contested intel of a nuclear weapons program in Iraq (the yellowcake and the aluminum tubes). It wasn’t about some rusted old artillery rounds with chemical weapons in them.
1) People I trust are skeptical, including people who are opposed to gain of function research. I've found Angela Rasmussen to be one of the better voices in terms of discussing the evidence for a natural origin, but she's far from the only one.
2) We have had two naturally occurring coronavirus epidemics during my career. A third is all but inevitable -- I wrote a grant in October 2019 suggesting a novel coronavirus as an example case for a modeling exercise, for example (sadly, said grant didn't get funded). So for me, there's a very strong prior on coronaviruses emerging as significant public health threats.
3) At the same time, I've come to distrust many of the voices who push the lab leak hypothesis, either because they're obviously doing so for geopolitical reasons, or because they've become addicted to being "the lone voice in the wilderness", despite it not being a risky position to take.
4) The lab leak hypothesis, in terms of evidence, relies on WIV, the Chinese Government, the WHO, etc. being broadly incompetent except when it comes to the characterization of the initial cases when SARS-CoV-2 emerged, which is arguably the hardest part of any outbreak.
My prior is that it is a zoonotic spillover event. Not necessarily that one, though there is some good evidence for it.
There were no similar reports in another place on this planet. (Since 99% of other places do not have full control of media and many have better healthcare so if it happened it would be less likely to go unnoticed)

November Brazil could happen because December is when rumours already circulated in China and October is when it was out in Wuhan already per your link.
April Brazil I don't know what to tell you, no sources support the wild claim that it was NOT a data error.
> 2 months before it came out of wuhan
Source? I bet it came out earlier. It was circulating in Wuhan before the pandemic according to WHO. Just people in China who are more likely to get infected are less likely to travel abroad (social class/sanitary conditions/etc) but maybe one person brought it out.
> A joint study published by China and the World Health Organization at the end of March acknowledged there could have been sporadic human infections before the Wuhan outbreak.
> Researchers from Britain's University of Kent used methods from conservation science to estimate that SARS-CoV-2 first appeared from early October to mid-November 2019, according to a paper published in the PLOS Pathogens journal.

That makes it odd that you're promoting an author who has claimed such evidence shows conclusively that spillover into humans--and not just a super-spreader event--occurred in the Huanan Seafood Market. I suspect that if you looked personally at the methodology behind the conflicted (Rasmussen's doctorate was under Vincent Racaniello, a longtime proponent of high-risk virological research) authors' claims, then you'd find them much less worthy of repetition.
> There’s really no explanation other than that the virus started spreading in the human population at that market
https://www.theguardian.com/world/2022/aug/13/angela-rasmuss...
The claim that the location of spillover can be definitively localized within hundreds of meters from epidemiological data is core to the predominant theory of natural zoonotic origin, from an overlapping set of authors including Rasmussen.
Theories of a research accident almost never assume such localization is possible, not least because the earliest known cases weren't particularly close to the WIV. (If anyone's claiming otherwise, they've probably confused the WIV and Wuhan CDC.) So it's odd that you'd correctly note the near-impossibility of that localization, but then cite that as evidence against unnatural origin.
This makes me think you haven't looked much in the details yourself, and two of your four points above are explicitly arguments from authority. If you did look yourself, then I think your assessment might change.
The institute would never be full.
There is no "bring your child to work day" in China.
Weird conflation, unlikely... uunless you mean to muddy the waters and sow dis-information.
Why would Wuhan center being empty represent anything?
People don't rush to a random (unrelated) building when they get sick at the "market".
Coincidence, surely?
What are the chances of having a specialized infectious disease center next to where that type of disease spontaneously emerged?
More or less likely than a bat having sex with a panda possum?
No one, not even the cowardly academics, believed it.
This frankly makes me distrust you; in 2020-2022 this was absolutely a risky position to take for most public figures, let alone those on academia, let alone those connected to epidemiology. This remains the only time and topic I've seen blanket banned from discussing across all major US social platforms. Try looking up what the vibe was like in 2020-2021 especially.
It still isn't even acceptable to acknowledge the (blatant) possibility that Omnicron was intentionally leaked because of low vaccine effectiveness.
Opinions do correlate in the general public, and I guess that's why you've made that link. I don't think that trend holds among scientists, though--Deigin, Chan, Ebright, Bloom, etc. all have quite ordinary views on vaccine risk and efficacy.
Yet you propose no thoughts of your own. You only base it on your belief in people around you and your disbelief of people you assume are political. This sounds not scientific at all. Are you really an epidemiologist?
I was honestly hoping for more given that you’re supposedly an epidemiologist.
This is the problem with virology, it IS GoF. Expecting virologists to be objective in this is expecting the impossible, like expecting the WHO to apologize for sending Daszak as head of the fact finding mission. They were either THAT incompetent or THAT self interested in maintaing GoF/virology, damn the truth.
I suspect virologists still see themselves as guards on the wall and that we can't handle the truth. Which we already know from the early emails is how they thought early on, why should I assume their propensity for dishonesty has changed?
