A long Youtube episode that has virologists discussing the research paper about SARS-COV2 origins:TWIV post
Here is the preprint:Preprint
It should be published in Nature pretty soon.
Look at Figure 2 if you want to see the RNA sequence map showing all the other bat corona viruses that share segments with SARS-COV2.
Where it says MULT, that means multiple different viruses share that segment. Segment 13 is the one segment that none of these viruses share.
