[GraniteGrok] Some new research from two Japanese scientists has discovered, or at least posits (using science), "That the Omicron variants are formed by a completely new mechanism that cannot be explained by previous biology." What they mean is that they do not appear to have occurred naturally.
To determine the order of mutations leading to the formation of the SARS-CoV-2 Omicron variants, we compared the sequences of 129 Omicron BA.1-related, 141 BA.1.1-related, and 122 BA.2-related isolates, and attempted to clarify the evolutionary processes of SARS-CoV-2 Omicron variants, including the order of mutations leading to their formation and the occurrence of homologous recombination. 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, .. |
