The nine facts about the origin of SARS-CoV-2 that everyone needs to know are as follows: 1) SARS-CoV-2 is related to bat SARS-like coronaviruses from southern China and northern Laos. 2) SARS-CoV-2 entered humans in or near Wuhan in August-November 2019.
@R_H_Ebright Don't leave out options that might challenge your own logic. You still need to address the possibility that the thriving wildlife market in Wuhan was the source for the original infection.
@itsmeagain4126 A superspreader event occurred in mid-December 2019 at Huanan Seafood Market. That superspreader event cannot, even in principle, explain the entry of SARS-CoV-2 into humans in August-November 2019. (For your reference, December 2019 occurred after August-November 2019.)
@R_H_Ebright @itsmeagain4126 Can you expand on this, I'm not following. I thought the reason to study the market was to show that the earliest cases *in Wuhan* originated there and thus rule out the WIV as a likely source for the Wuhan cases. Am I missing something?
@SashaGusevPosts @itsmeagain4126 Yes, But this works only if one ignores the fact tha August-November 2018 preceded mid-December 2019.

@R_H_Ebright @SashaGusevPosts @itsmeagain4126 where are all the cases in August to November Richard? And if this was true, why wasn't the D614G adaptation already fixed? Seems you're doing that 'date of MRCA=date of emergence' thing again.
