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.

    There’s a bunch of indications / conspiracy theories that it might have been a lab leak. Basically there’s not really a way to know unless the Chinese government starts being more forthcoming with information.

    The main reason the conspiracy theory started is because the city where it started had a world renowned virus research facility in it.

    Of course, the reason the facility is there in the first place is because Wuhan province is a place where a lot of viruses originate naturally (in bat colonies), so it makes sense you research the viruses close to their natural reservoir.

      This is disingenuous. RaTG13 was sourced in Tongguan in Mojiang Hani Autonomous County 1800km from Wuhan.
