Two experts argued in an op-ed in The Wall Street Journal on Sunday for the existence of “damning” scientific evidence in favor of the theory that the CCP (Chinese Communist Party) virus did not make a natural jump from animal to human but was bio-engineered in a Chinese lab.
Dr. Steven Quay, who holds an M.D. and Ph.D. from the University of Michigan, and Richard Muller, emeritus professor of physics at the University of California, Berkeley, said that two key pieces of evidence—one relating to gene splicing and the other to a lack of virus diversity—strongly suggest a lab origin of the outbreak that has infected over 173 million people worldwide.
“The presence of the double CGG sequence is strong evidence of gene splicing, and the absence of diversity in the public outbreak suggests gain-of-function acceleration. The scientific evidence points to the conclusion that the virus was developed in a laboratory,” the pair wrote.
Gain-of-function research involves manipulating a virus’s genome to increase its virulence or transmissibility to better understand and predict the emergence of disease-causing agents and make it easier to come up with a solution before the disease emerges as a pandemic. Quay and Muller wrote that the most common genome pairing used in gain-of-function experiments on coronaviruses is CGG-CGG, or double CGG, which is spliced into a “prime location” in the genome, spurring the production of two arginine amino acids in a row and boosting a virus’s lethality.
This “alters the virus spike protein, rendering it easier for the virus to inject genetic material into the victim cell. Since 1992 there have been at least 11 separate experiments adding a special sequence to the same location. The end result has always been supercharged viruses,” the scientists wrote.
Genomic insertion can take place naturally in a process called recombination, but in cases of a natural splicing, one of 35 other possible genomic sequences would be far more likely to appear than the double CGG, Quay and Muller wrote.
“In the entire class of coronaviruses that includes CoV-2, the CGG-CGG combination has never been found naturally,” they wrote. “That means the common method of viruses picking up new skills, called recombination, cannot operate here. A virus simply cannot pick up a sequence from another virus if that sequence isn’t present in any other virus.”
But in lab-based gain-of-function experiments, the CGG sequence is the pair of choice, they said.
“That’s because it is readily available and convenient, and scientists have a great deal of experience inserting it,” they wrote. “An additional advantage of the double CGG sequence compared with the other 35 possible choices: It creates a useful beacon that permits the scientists to track the insertion in the laboratory.”
While the pair acknowledged that the double CGG sequence could have appeared naturally in SARS-CoV-2, the scientific term for the CCP virus, the fact that it is present in the virus puts the burden of proof on opponents of the lab theory.
“Proponents of zoonotic origin must explain why the novel coronavirus, when it mutated or recombined, happened to pick its least favorite combination, the double CGG. Why did it replicate the choice the lab’s gain-of-function researchers would have made?” the wrote.
“At the minimum, this fact—that the coronavirus, with all its random possibilities, took the rare and unnatural combination used by human researchers—implies that the leading theory for the origin of the coronavirus must be laboratory escape,” they added.
While the thesis that the virus leaked from a lab at the Wuhan Institute of Virology was initially dismissed by a number of prominent scientists, including White House adviser Dr. Anthony Fauci, there’s recently been a remarkable pivot. Fauci has acknowledged that he’s no longer that sure that the virus didn’t leak from the lab, while President Joe Biden has ordered U.S. intelligence to “redouble” its efforts to examine both theories, which he characterized as equally plausible.
Quay and Muller said that the second key piece of evidence that supports a lab leak theory has to do with the genetic diversity of the CCP virus compared to the coronaviruses that caused SARS and MERS.
SARS and MERS, which were confirmed to be of natural origin, “evolved rapidly as they spread through the human population, until the most contagious forms dominated,” they wrote.
Yet the CCP virus “appeared in humans already adapted into an extremely contagious version,” the pair noted, with no significant mutations occurring in the virus until months after the outbreak.
“Such early optimization is unprecedented, and it suggests a long period of adaptation that predated its public spread,” they wrote, arguing that there’s only one way this could be achieved, namely through “simulated natural evolution” by growing the virus on human cells under lab conditions.
Chinese communist authorities have repeatedly rejected the lab leak theory, while a report from the World Health Organization (WHO) published in March concluded that the CCP virus likely spread to people through an unknown animal. However, WHO Director-General Tedros Adhanom Ghebreyesus said at the time that the mission to study the origin of the virus didn’t adequately analyze other theories and, on May 25, the United States urged the WHO to launch a fresh probe into the origin of the virus, highlighting the need for transparency.
More than a dozen nations, including the United States and the European Union, have raised concerns about the phase one WHO study into the origin of the virus, pointing to the report’s significant delay and China’s refusal to share crucial raw data.
In March, Quay coauthored a study that relied on Bayesian analysis to conclude “beyond a reasonable doubt that SARS-CoV-2 is not a natural zoonosis but instead is laboratory derived.”
