This comes a no surprise. What were the chances that Ground Zero for SART-CoV2 just coincidentally happened outside a Chinese virology lab?
A new study on the origins of the pandemic, “Endonuclease fingerprint indicates a synthetic origin of SARS-CoV2,” published on the preprint server bioRxiv, concludes that it is highly likely that the SARS-CoV-2 virus that causes COVID-19 originated in a laboratory. The odds of a natural origin, according to the study, are placed at less than 1 in 100 million.
Unlike previous studies that analyzed qualitative aspects such as virus features, the new study for the first time assesses the likelihood of a laboratory origin on a quantitative basis. This breakthrough methodology allowed the authors to present objective findings that appear to exceed any previous studies.
Significantly, the new study does not rely on any of the known evidence pointing toward a lab origin of the SARS-CoV-2 virus. For instance, it does not take into consideration the highly unusual Furin Cleavage Site that makes the virus particularly virulent and which it is widely thought to have been insertedinto the virus at the Wuhan Institute of Virology. Nor does it factor in the huge coincidence that the pandemic started on the door steps of the world’s premier coronavirus laboratory
Instead, the authors—Valentin Bruttel, a molecular immunologist at the University of Würzburg in Germany; Alex Washburne, a mathematical biologist at Selva Science; and Antonius VanDongen, a pharmacologist at Duke University—took a novel approach that assesses the genesis of the SARS-CoV-2 virus from an entirely new angle. The authors examined tiny fingerprints left behind in the process in which viruses are assembled in laboratories. While use of seamless genetic engineering techniques in creating viruses in laboratories typically conceals evidence of manipulation, the new study developed a statistical process for uncovering such hidden evidence by comparing the distribution of certain strands of genetic code in wild viruses and lab-made viruses.

In other words, one of the main purposes of manipulating viruses is to better understand which parts of viruses make them particularly infectious, lethal, or transmissible. A related purpose is to develop bioweapons but the authors of the new study reject the idea that that is why SARS-CoV-2 was made. They believe that the virus “was assembled in a lab via common methods used to assemble infectious clones pre-COVID.”

Piecing together viruses in labs is subject to limitations. The genetic information for SARS-CoV-2 is contained in 30,000 base pairs of RNA nucleotides. However, the 30,000 base pairs are not pieced together all at once. Instead, laboratory viruses are assembled from a collection of smaller strands of base pairs that are later “glued” back together as chimeras, or compounds. Enzymes are used to cut viruses apart at certain points along the DNA strand (laboratories use DNA instead of RNA as it is more stable; the assembled DNA is then added to bacteria that create RNA viruses).

While naturally occurring cutting sites and cutting sites added in a lab are biologically indistinguishable, Bruttel, Washburne and VanDongen hypothesized that they could detect a “very subtle but identifiable fingerprint” by plotting the distribution of the cutting sites on the SARS-CoV-2 virus. They would then compare this to the distribution of such sites on wild-type SARS viruses, as well as on other, pre-pandemic lab-made SARS viruses. They carried out their analyses for the most commonly used enzymes (biological “scissors”) which, according to a series of pre-pandemic publications from the Wuhan Institute of Virology, were also used for experiments in the Wuhan lab.

Bruttel, Washburne, and VanDongen estimate that the odds that the SARS-CoV-2 virus arose naturally lie between 1 in 100 and 1 in 1,400. However, this estimate only factors in the distribution of cutting sites. The authors also observed a concentration of mutations within the cutting sites that was “extremely unlikely in wild coronaviruses and nearly universal in synthetic viruses.” The estimate drops to a 1 in 100 million chance that SARS-CoV-2 was a naturally-occurring virus if these mutations are factored in. When considering additional criteria, such as the fact that the “sticky ends” where the viruses are “glued” back together all happen to fit perfectly, the authors estimate the odds of a natural origin to be even lower.
The authors conclude that SARS-CoV-2 was assembled in a lab using common methods for assembling viruses. The authors do not speculate on which lab the virus escaped from.
