The quote is directly on the complete statement’s core issue: whether COVID-19 came from a lab-related incident or from nature. In source context, it is presented as a scientist’s argument about COVID-19 origins and clearly makes one stance on that exact lab-vs-natural question determinable.

The quote directly opposes the statement: the author says there is "zero evidence" COVID-19 came from a lab and "ample evidence" it came from nature; the source context also says he "dismissed the theory" that it escaped from a lab.

Yes. The provided PRWeb URL contains the quote verbatim and attributes it to Vincent Racaniello: "there is zero evidence that this virus came from a lab, and there is ample evidence that it came from nature." The page is dated June 21, 2021; Columbia also identifies Vincent Racaniello as a microbiology and immunology professor, and the linked CGTN item is from June 15, 2021, so the stored month-level date "Jun 2021" is acceptable.
