The working paper forensically dismantles the natural origin case made in Proximal Origin and concludes, “The arguments that Andersen et al. use to support a natural-origin scenario for SARS-CoV-2 are based not on scientific analysis, but on unwarranted assumptions.”
The existence of this internal Pentagon paper is crucial, as it proves that government officials were well aware in the early months of the COVID-19 pandemic that there was no evidence to support a natural origin of the COVID-19 virus. Given the crushing discrediting of Proximal Origin, Pentagon officials would also have been aware of Fauci’s efforts to seed a false narrative about the origin of COVID-19.
What wasn’t known at the time was that Fauci not only knew the authors well but had personally led the effort to have Proximal Origin written.
Yet while the public was being told by Fauci and the media that Proximal Origin had settled the origin debate, Pentagon researchers came to a very different conclusion.
Chretien and Cutlip found that COVID-19’s features, which Proximal Origin ascribed to natural evolution, were actually “consistent with another scenario: that SARS-CoV-2 was developed in a laboratory, by methods that leading coronavirus researchers commonly use to investigate how the viruses infect cells and cause disease, assess the potential for animal coronaviruses to jump to humans, and develop drugs and vaccines.”
One of those features is COVID-19’s furin cleavage site, which makes the virus particularly infectious in humans. This feature has never been observed in any naturally occurring betacoronaviruses. Proximal Origin claimed that since this feature wasn’t part of any known laboratory-generated virus, it had to have arisen through a “natural evolutionary process.” As Chretien and Cutlip pointed out, this argument is “not based on scientific analysis but on an assumption that the prior work would have been published if it had been done.”
According to the Pentagon report, a similar argument made in Proximal Origin about COVID-19’s receptor binding domain, the part of a virus that allows it to dock to cells in humans or animals, was “not a scientific argument but rather an assumption of intent and methodology for a hypothesized scientist.”
The Pentagon report also highlights a major logical flaw in Proximal Origin, in that it relies on a lack of publications about particular aspects of coronavirus engineering as a reason to conclude that such engineering didn’t take place. For instance, Proximal Origin claims that “the genetic data irrefutably show that SARS-CoV-2 is not derived from any previously used virus backbone.”
As Chretien and Cutlip pointed out, “The absence of a publication does not mean that the research was not done.”
In what’s perhaps the most notable portion of the Chretien and Cutlip paper, the authors note the collaboration between Ralph Baric of the University of North Carolina, a pioneer of gain-of-function experiments, and Shi Zhengli, director of the Wuhan Institute of Virology. As Chretien and Cutlip pointed out, Baric and Shi carried out an experiment in 2015 that mirrored how the COVID-19 virus would have been engineered in a laboratory. The direct link between the Wuhan Institute and the know-how needed to make COVID-19 wasn’t mentioned in Proximal Origin.
While Chretien and Cutlip didn’t offer a definitive answer on the origin of COVID-19, they concluded that none of the arguments in Proximal Origin lessened the plausibility of a laboratory origin. Proximal Origin claimed to have done the exact opposite.
Given the sweeping nature of the takedown of Proximal Origin, the question is why the public wasn’t told about the Pentagon’s paper, which was fully taxpayer-funded.
Instead, the Pentagon, which was led at the time by Trump appointee Mark Esper, allowed Fauci’s false origin narrative to fester. One of the two authors, Cutlip, left the Department of Defense in 2021; the circumstances of his departure aren’t known. Cutlip’s bio states that he’s currently a visiting professor at Fairmont State University in West Virginia.
The bio also states that Cutlip was part of “the Corona Virus Task Force, providing intelligence to the President of the United States.” It isn’t known whether Cutlip shared his insights with either Trump or President Joe Biden.
