AFAIK the known animal reservoirs got it from humans. Do you know any animal reservoir that we still don't know how the animals have got it?

  We don't, and that's the issue, we can't know unless we find an ancestor virus. It's also very possible if could have wiped out the original virus in all original reservoirs. It's very difficult to do this now and for endemic viruses in general, and it took a very very long time to do for SARS where this wasn't a problem.

    I thought they thought it might be pangolins? https://pubmed.ncbi.nlm.nih.gov/32380510/ https://pubmed.ncbi.nlm.nih.gov/32380510/

      Yeah, that's a theory, but I don't think it's settled yet

      That is a very old article in pandemic research time. Pagolins aren't thought to be the likely intermediate animal any more.
