Unnatural evolutionary processes of SARS-CoV-2 variants and possibility of deliberate natural selection

As a result, we concluded that the formation of a part of Omicron isolates BA.1, BA.1.1, and BA.2 was not the product of genome evolution, as is commonly observed in nature, such as the accumulation of mutations and homologous recombinations. Furthermore, the study of 35 recombinant isolates of Omicron variants BA.1 and BA.2...
