> Given that furin cleavage signals are present in other coronaviruses at exactly that point in the S1/S2 boundary region, it only LOOKS unusual, especially against the backdrop of SARS. The preponderance of evidence, coupled with Ockham’s razor (that the simplest explanation is preferred) dictates that the PRRA sequence has been conserved in nCoV2019 from a long ago ancestor virus. It is not of suspicious origin. The closest bat virus sequence is really not close at all. https://virological.org/t/tackling-rumors-of-a-suspicious-origin-of-ncov2019/384 https://virological.org/t/tackling-rumors-of-a-suspicious-or...
