It is amazing how the Terb Experts here are more knowledgeable than heads of viral genomics and scientists, mind-boggling I tell you.
The claim Covid-19 leaked from a Chinese laboratory dates from early in the pandemic. Here's what we know.

A natural origin is still the more likely theory, said Professor David Robertson, head of viral genomics and bioinformatics at the University of Glasgow.
"There's been an accumulation of evidence (what we know about the viruses biology, the close variants circulating in bats and locations of early human cases) that firmly points to a natural origin centred on the Huanan market in Wuhan city," he said.
Prof Alice Hughes from the University of Hong Kong agreed. She said the US Department of Energy's conclusion that the virus was most likely the result of a lab leak in Wuhan "appears not to be based on new evidence, and remains the weaker of the two main hypothesis of the origin of the virus".
