@gdemaneuf The reason why #ProximalOrigin authors & Friends are pushing the multiple spillover hypothesis so hard is because otherwise the market zoonosis hypothesis has no legs.
But this multiple spillover hypothesis is itself not supported by any evidence.

Reporters, incl some from 2020, rush out headlines amplifying this claim. /20

After reading the preprints, I quickly identified major scientific issues or misunderstandings undermining the main claims of the highly reported Worobey et al. preprint.
I will address the 11 key claims of this preprint listed in their discussion.
