"By comparing the available genome sequencing data for the virus chains, we can firmly determine that SARS-CoV-2 [as the new coronavirus is called] originated from natural processes," said Kristian Andersen in a note. , associate professor of immunology and microbiology at Scripps Research, the American nonprofit medical research center. According to the research, the molecular structure of the new coronavirus would not be something done in the laboratory because it is very different from that seen in other diseases of the same group. However, it has similarities to known viruses that affect bats and pangolins, which would not be used in genetic engineering.
Researchers from universities in the United States, United Kingdom and Australia say the virus has a natural origin. "Our analysis clearly shows that SARS-CoV-2 is not a laboratory building or a virus that was purposely manipulated," says the article.
The study authors compared the genetic structure of SARS-CoV-2 with that of other viruses in the same family. The scientists stressed that, if there were genetic manipulation in the laboratory, the structure of the new coronavirus would be similar to that of other existing organisms. In other words, if someone wanted to create a new virus in order to cause disease, they would use a known "mold". "The genetic information shows irrefutably that SARS-CoV-2 is not derived from any central virus structure used previously," says the research.
Another important feature rules out the theory of human creation. The researchers analyzed the structure that the virus uses to "cling" to the outer walls of other cells, in particular the so-called receptor-binding domain (RBD). This part of SARS-CoV-2 was so effective in connecting to human cells that scientists concluded that it was the result of natural selection, not genetic engineering.
