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.

    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.

        I’d more think accidentally if anything. And more obvious is just medical research.
