    Then there is the whole lineage A and B = the animals in the Huanan market are lineage B, so how did lineage A get started? The NEJM paper says other case werelinked to other markets, but which ones and which were sequenced Idon't know,.

    My read as well -on Marion.

    Yes, Marion is cautious so they must have something. Hope they release soon. I may have told you but I also heard that they had discounted the Dec 1 case and the earliest known one is now Dec 8. I also think I heard that while this patient had no link to the market his parents had some sort of link to another live animal market. Not sure is this issomething or not.

    Dec 8 is consistent with the graph from the CCDC NEJM paper.

    Pathetic

    I think there's _a lot_ of early unsampled diversity, which can help explain the A vs B split. Much focus turned to the Huanan market, where super spreading might have occurred, so we end up having very biased sampling early on.

    That seems right. But is the diversity in unsampled humans, unsampled animals or perhaps both. Only A and B lineages made it through the bottleneck.

    Another way to ask the questions: B came from A as Andrew said in the NatMicro paper. But did the split happen inan animal or after the human to animal transfer? Maybe doesn't really matter.
