The new coronavirus SARS-CoV-2, which appeared in Wuhan in China in 2019, and since then caused a large-scale epidemic COVID-19, was the result of natural evolution. To such conclusion scientists of the research Institute of SCRIPPS, who disclosed the true nature of the virus, after analyzing its genome.

Data analysis of the sequencing of the genomes of known strains of coronavirus have shown that SARS-CoV-2 arose as a result of natural processes. In particular, biologists have studied genes encoding proteins that form spikes — the spikes, allowing the virus to join the cage and get inside of it. Scientists focused on two important features: the receptor-binding domain (RBD) and the site of cleavage, which also enables the virus to penetrate the cell.

It turned out that RBD have evolved to efficiently interact with the cellular receptor ACE2. This domain is so effective to bind to human cells, which can not be artificially created to date. In addition, if the virus was created artificially, it would have used the virus that is already known to cause disease. However, the basis of SARS-CoV-2 differs significantly from the known coronaviruses infecting humans.
