Here's as good a place to start as any: it's beginning to look like they made SARS-2-Covid by splicing bits and pieces from FIP into a bat coronavirus.

I think we need a "The Lights Of Perverted Science" category.

This is an interesting idea as to why one might have wanted to engineer a non-canonical FCS into proto-SARS2: they could have been inspired by how a mutated FCS in feline CoVs turns a harmless FECV into a deadly FIPV. Some of those deadly strains had their FCS mutate into PRRAR: https://t.co/cBLexSRU8x
