    The only real evidence I can see is the steadfast refusal of cooperation from the Chinese authorities, the creation and spread of false evidence and rumours, the distruction of evidence from the early days of the outbreak, the deaths and disappearances of people connected to the origins of Covid 19 – and so on and so forth!
    What does all that say to you?
    Two things:
    Or being extremely naive to believe otherwise..

      The whole thing says that no-one wanted to be the official upon whose desk the lack of enforcement around the markets landed. All you needed is a few folks with a bit of power trying to duck the problem for the problem to completely blow out. The US had similar problems, where the orange mandarin stocked the response with spineless muppets.

    The podcast that listener Brad is looking for is “Debunk the Funk.”

    And another absolute banger of a show, at least for us non-biologist listeners

    Thank you for this presentation. I was surprised by the claim that the tMRCA of SARS-CoV-2 was Dec 10, 2019, the day when the earliest market case has been documented. A collection of 10 separate studies have dates ranging from mid-Oct to Mid-Nov. The earliest date I have seen is actually from an 83,688 genome study and reports a tMRCA of Aug 16, 2019 with a 20 day 95% CI:

    Xia X. Dating the Common Ancestor from an NCBI Tree of 83688 High-Quality and Full-Length SARS-CoV-2 Genomes. Viruses. 2021 Sep 8;13(9):1790. doi: 10.3390/v13091790. PMID: 34578371; PMCID: PMC8472983.

    If the first market case is weeks or months after ‘Patient Zero’ how can the market data inform the origin?
