James Lynch writes for National Review Online about an interesting development in the search for COVID-19’s origin.

An independent scientist and accomplished businessman delivered testimony before the Senate Tuesday morning going into detail on why he believes the coronavirus originated from a lab in Wuhan, China.

Dr. Steven Quay, a scientist who authored a widely viewed Bayesian analysis concluding that the virus originated from a lab, testified before the Senate Homeland Security and Governmental Affairs Committee and read a detailed opening statement dissecting the data backing up his belief that the virus came from the Wuhan lab.

Quay, who has a Ph.D. from the University of Michigan and was on the faculty at the Stanford University School of Medicine, described “six approaches” that inform his view that the virus emerged from a lab: the timing of the virus’s emergence around Wuhan, data from the wet market at the center of the natural-origin theory, research activities at the Wuhan Institute of Virology (WIV), the lack of evidence consistent with a natural origin, the genomic sequence of the coronavirus, and specific features of the early genomes of the coronavirus.

After introducing each approach, Quay quickly rattled off significant details from his written testimony to substantiate his claim that the existing fact set is incompatible with the natural-origin theory.

“These fourteen observations provide evidence the virus was spreading in Wuhan and outside Wuhan in the early fall of 2019, two to four months before the first case in the Hunan Seafood Market. All market cases have onset in December 2019, and thus are well after the outbreak began. This establishes the market is not the origin,” Quay said upon describing the virus’s apparent spread before it was discovered at a wet market in Wuhan.

Quay proceeded to describe the extensive evidence that the virus could not have jumped from a bat to another animal before infecting humans at the wet market, pointing out that the virus has not yet been found in any animal in the wild despite extensive efforts to do so.
