These conclusions were made due to the similar nature of the accumulated mutations in the genome of SARS-CoV-2 and the two viruses that
During the study, the authors took it as an axiomthe idea that the pattern of accumulation of mutations in the genome of a particular virus will greatly depend on how the immune systems of the animals or people it usually infects interact with it.
Accordingly, the similarities in how the genome of the virus changed in the recent past will show in whose organism it evolved.
The authors of the new work studied how mutations accumulate in the genomes of several dozen coronaviruses.
Evolutionary history of the origin of coronavirusstill remains a mystery, since the SARS-CoV-2 genome is only 96% identical to the RNA structure of its closest relative, the bat virus RaTG13. We clarified this situation by learning about the similarity in the pattern of accumulation of mutations in the genomes of SARS-CoV-2, RaTG13 and another bat coronavirus, RshSTT182.

In this regard, the scientists stated that almost all the development of SARS-CoV-2 before the transition to the human population took place in the body of bats.
