Omicron genetics and early transmission patterns are characterized in new study
The Omicron variant of SARS-CoV-2 diverged from previous SARS-CoV-2 variants as a result of adaptive evolution, in which beneficial mutations are passed on to future generations through natural selection, rather than through recombination between previous variants, according to a large international team of researchers. The study, which published recently in Nature, is the first to describe the genomic profile of Omicron and explore the origins of the variant.
