The genomic features described here may explain in part the infectiousness and transmissibility of SARS-CoV-2 in humans. Although the evidence shows that SARS-CoV-2 is not a purposefully manipulated virus, it is currently impossible to prove or disprove the other theories of its origin described here. However, since we observed all notable SARS-CoV-2 features, including the optimized RBD and polybasic cleavage site, in related coronaviruses in nature, we do not believe that any type of laboratory-based scenario is plausible. https://www.nature.com/articles/s41591-020-0820-9?sf231597135&fbclid=IwAR3OAHAvxCDMqhwPLV-H4qdk3CnFvEk32-aabVVLSZQIIqdP534YQvMQjtI |
