    The Intergovernmental Panel on Climate Change first met in 1990, where it predicted that GHGs could fuel global warming. Even as more evidence accumulated, efforts to sow doubt delayed action. The “natural origins” vs “lab leak” debate around COVID-19 has entered this realm...pic.twitter.com/kZaGAOXMmg

        Doubters of climate change often called for “direct evidence” -- or irrefutable proof that carbon begets warming begets catastrophic climate/weather. Ex. The National Academy of Sciences report on June 7, 2001 was followed four days later by these comments by Pres. Bush.pic.twitter.com/FwUsEamPyB

        For months, I’ve watched the “lab-leak” hypothesis creep from conspiracy theory into the mainstream. This culminated last week, when Science Magazine published a letter signed by 18 scientists equating the “natural origins” hypothesis with the idea of accidental lab leak.pic.twitter.com/RNNHXHAAVW

        Overall, the letter calls for more investigation/transparency in China, which most outside of Beijing can agree with. But it creates a false equivalence between natural origins (supported by studies) and the lab-leak theory (no evidence).

        Many in the lab-leak camp (including a signatory on the Science letter) claim that SARS-CoV-2 was possibly bioengineered (again, no evidence, and it's countered by studies).

        1. Let’s start with Nicholas Wade, a former NYT writer who once wrote a book on race and genetics that was so problematic that it was openly denounced by 143 scientists, including ones who said he misrepresented their research… https://cehg.stanford.edu/letter-from-population-geneticists …pic.twitter.com/Ygo9Pyo2Pn

        Wade recently penned an op-ed in @BulletinAtomic where he made two central claims about why SARS-CoV-2 could be bioengineered or involve gain of function research. Both are unsupported, but the second on “serial passage” is objectively incorrect...pic.twitter.com/4g9IWyLKUv

        Serial passage is a lab method of growing a germ. Take a virus, drop it into a petri dish/beaker with some cells and let the germ infect/multiply. Wade says this could have been done to breed SARS-CoV-2 without leaving a sign—a point opposed by multiple studies of the virus.pic.twitter.com/AWXh8N0wJZ

        The takeaway is that the SARS-CoV-2 virus mutates in predictable ways when you remove it from a body and put it into a petri dish. These changes include genetic deletions that make the coronavirus less likely to infect humans.pic.twitter.com/Dif7CHiiSI

        Wade’s OpEd, along with almost every “lab-leak” article, omits this research even though these studies have existed since last summer. These findings should surprise no one. A common thread in biology is that if you move an organism from one environment to another, it changes.

        There is no way to bioengineer a virus without serial passage. The germ would need to be grown and isolated, over and over. There is no gain of function research without this first step.

        But SARS-CoV-2 is so highly adapted to being inside living mammals, that once you move it into a petri dish, it leaves a trail of evidence.

        Other evidence points to SARS-CoV-2 being naturally derived after adaptation to an immune system. But it’s fairly heady, so I’ll just mention these four studies...(again, more evidence of natural origins)...and move on...pic.twitter.com/RciQRL8yIc

        The SARS-CoV-2 spike carries a feature called the furin cleavage site (FCS), which is required for the virus to infect our cells. The lab-leak crew says this FCS is unusual...too unusual... which again is not supported. See thread by @K_G_Andersen https://twitter.com/K_G_Andersen/status/1391507230848032772/ …

        i know i'm a bit late to the party, but to anyone who thinks #SARSCoV2 FCS is engineered, if you were actually engineering in an FCS: 1) you'd use something you've seen before, say RRSRR in HKU1. turns out this particular one *does* show up in some strains of FIPV but it's rare.

        3. Lab leakers say that finding SARS-CoV-2 (or a 99% identical relative) in a bat or intermediate animal host is the only suitable direct evidence for natural origins. I get that. Scientists identified animal hosts of past emergent coronaviruses—SARS-CoV-1 and MERS—within a year

        The intermediate host of the 2002 SARS was identified in four months...why didn’t the same happen this time? I don’t know. China could have invited independent investigators after their first wave but didn’t. Maybe it was the trade war? Maybe they lost trust in westerners?

        Or perhaps, the lab-leak crew is masking their lack of evidence by raising a bottomless pit of hypotheticals. Proving a negative is challenging, and if an animal is harboring SARS-CoV-2 in the wild, it could be extremely difficult to find without more cooperation from China.
