Virologist Disputes WSJ Report on a Minority Opinion Suggesting Covid 'Lab Leak' Origin

Three long-time Slashdot readers all submitted this story - schwit1, sinij, and DevNull127. DevNull127 writes: Four U.S. agencies have concluded that the Covid-19 virus originated at the Wuhan market, the Wall Street Journal reports. The U.S. National Intelligence Council reached the same conclusion. Then there's two more agencies (including America's CIA) that are "undecided." But there is one agency that decided - with "low confidence" - that the virus had somehow leaked from a lab. (And the FBI also decided with "moderate confidence" on that same theory.) "The new report highlights how different parts of the intelligence community have arrived at disparate judgments about the pandemic's origin," writes the Wall Street Journal - adding that unfortunately U.S. officials "declined" to give any details on what led to the Energy Department's position. The Wall Street Journal also notes:Despite the agencies' differing analyses, the update reaffirmed an existing consensus between them that Covid-19 wasn't the result of a Chinese biological-weapons program, the people who have read the classified report said.... Some scientists argue that the virus probably emerged naturally and leapt from an animal to a human, the same pathway for outbreaks of previously unknown pathogens. Intelligence analysts who have supported that view give weight to "the precedent of past novel infectious disease outbreaks having zoonotic origins," the flourishing trade in a diverse set of animals that are susceptible to such infections, and their conclusion that Chinese officials didn't have foreknowledge of the virus, the 2021 report said. Also responding to the Department of Energy's outlying position was a virologist at the Vaccine and Infectious Disease Organization at Canada's University of Saskatchewan, who posted a series of observations on Twitter:The available evidence shows overwhelmingly that the pandemic started at Huanan market via zoonosis. I have no idea what this evidence that Department of Energy has is. All I know that it is "weak" and resulted in a conclusion of "low confidence". It reportedly comes from the DOE's own network of national labs rather than through spying. But I do know that to be consistent with the available scientific evidence, the DOE has to explain how the virus emerged twice over 2 wks in humans at the same market the size of a tennis court, over 8 km & across a river from the only lab in Wuhan working on SARSr-CoVs.... Claims of a progenitor at WIV are pure speculation & unsupported by evidence.... Despite 3 years of a global search for this evidence, it has not materialized, while evidence supporting zoonosis associated with Huanan has continued to stack up. At some point, an absence of evidence might just be evidence of absence.
