the researchers were split on whether the virus leaked from the lab. some people still do believe that. what is the evidence that they cite in their argument? so, really, the only evidence that it emerged from a lab is that — the location of the earliest cases in this pandemic, wuhan. wuhan does have a laboratory there that engages in research with coronaviruses. it is far from the caves that are normally the hosts of bat colonies and they haven't been able to determine what species might have spread the virus initially. that's it. that's the entire case for lab accident — for it being a lab accident. everything other than that really is just speculation. the evidence for it being a spillover is that, you know, every other coronavirus outbreak that has happened has occurred from the virus jumping from animal to a person.
