Andersen and colleagues set out to see what they could deduce about the origin of the new coronavirus from analyzing the genomic data available.As the authors mention in their paper, since the start of the COVID-19 outbreak, researchers have been trying to grapple with the origins of the virus that caused it.Initially, experts linked the virus to the seafood market in Wuhan, China, while later study papers suggested that the virus may have spread to humans from illegally trafficked mammals called pangolins. If scientists had engineered the new coronavirus purposely as a pathogen, explain the researchers, the starting point would likely have been the backbone of another virus in the coronavirus family.However, the backbone of SARS-CoV-2 was very different than those of other coronaviruses and was most similar to related viruses in bats and pangolins.“These two features of the virus — the mutations in the RBD portion of the spike protein and its distinct backbone — rule out laboratory manipulation as a potential origin for SARS-CoV-2,” explains Andersen.“By comparing the available genome sequence data for known coronavirus strains, we can firmly determine that SARS-CoV-2 originated through natural processes.” – Kristian AndersenJosie Golding, Ph.D., who is the epidemics lead at the Wellcome Trust, a research charity based in London, United Kingdom, did not participate in the study but comments on its significance.
