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.

    I do recall that story. What I don’t get is why the intelligence agencies had any say in the likely origin. It’s not a factor of “if the virus was in a lab.” It could have been. The fact is that even back then when they had the virus sequenced, they could clearly see it came from a zoonotic source, probably the same one with SARS.

    The thing that irked me so bad about it is that it highlights the discrepancy between science and suspicion. Think of how vital DNA has been to crime prosecutions or exonerations. The same thing applies here.

      If it did originate during the development of a bioweapon then you would want the intelligence agencies to be as informed as possible. Thankfully none believe that to be the case.

      Yes. 96% zoonotic. It’s that latest 4% that is of interest. Particularly the fully functional cleavage site at the S1, S2 junction.
