Most lab-leak discussions I come across focus on the WIV. And many sources mention a lab leak is inconsistent with the geographical evidence, e.g. the Guardian recently:
> Wray’s public endorsement of the lab leak theory runs counter to the conclusions of several prominent scientific studies, as well as the assessments of some other US intelligence agencies. [...] “Two prior studies – one of which I co-authored – demonstrate clearly using multiple lines of evidence that the pandemic emerged into the human population at least twice over an approximately two-week period at or immediately upstream of Huanan market in association with the live animal trade,” Angie Rasmussen, a professor with the University of Saskatchewan in Canada, told the Guardian this week.
