A team of scientists say it is “beyond reasonable doubt” the Covid pandemic started with infected animals sold at a market, rather than a laboratory leak.

They were analysing hundreds of samples collected from Wuhan, China, in January 2020.

The results identify a shortlist of animals – including racoon dogs, civets and bamboo rats – as potential sources of the pandemic.

Despite even highlighting one market stall as a hotspot of both animals and coronavirus, the study cannot provide definitive proof.

The samples were collected by Chinese officials in the early stages of Covid and are one of the most scientifically valuable sources of information on the origins of the pandemic.

Their analysis was published last year and the raw data made available to other scientists. Now a team in the US and France says they have performed even more advanced genetic analyses to peer deeper into Covid’s early days.

    We’ll never hear the true story thanks to geopolitics.

    Frankly, the lab leak theory IMO is the most plausible. There are wet markets all over China and have been for…ever? I get that nobody can really predict a zoonotic crossover event, but they were literally experimenting with highly infectious coronaviruses in Wuhan at the time of the initial outbreak.

      People have been saying for decades before covid that the wet markets were a ticking time bomb. There has probably been viral outbreaks in the past, but the local population could have died off before it spread.

      I think a lab leak of a natural virus is plausible, but irrelevant.

        I think lax saftey when experimenting with highly infectious coronaviruses is very relevant.

        Either improve the protocols or don’t experiment.

          There’s a difference between lax safety and conspiracy to engineer a bioweapon. The main motivator of people pushing the Lab Leak conspiracy is that they want some villain to blame all this on.

            Not bioweapons. Covid isn’t dangerous enough.

            The prime conspiracy theory target is Anthony Fauci because some EcoHealth Alliance / NIH coronaviruses bat funding went to the Wuhan Institute of Virology.

            But you don’t need to subscribe to the Fauci Supervillan theory to suspect an accidental lab leak. China has already had 3 (2004, 2016, 2020) in this list. Pointing this out is not sino bashing (look at the number of US incidents). Accidental lab leaks happen all too regularly.

              Back to an earlier point you made, how is it relevant that it was an accidental lab leak anymore? It’s China, they’ve either made better safe guards against possible break outs or made superficial changes for appearances. The international community can’t punish them for an accident that also hurt themselves. Hell, we can’t seem to keep their coast guard from ramming other ships.

            Bioweapon is also a strawman in this case, he did not say that.

            In gain of function research more virulent strains are made to study and find cures against. So we have a better understanding of how these viruses mutate, what makes them tick and how we can disrupt that.

            Noone would intentionally set something like that loose.

              There are definitely people saying that covid was an engineered bioweapon and the people saying that have a huge overlap with the people saying that it was a lab leak. Conspiracy theorists need a villain with a plan to make sense of the work and that’s why the lab leak theory keeps coming up.
