Omicron is suspicious as fuck. The genetic distance from BA1 variant to Wuhan is so large it doesn't seem to be a descendant of that virus (they instead likely have a most recent common ancestor a few years back). The BA2 variant is distant from BA1 and Wuhan as well, most recent common ancestor estimated to be circa 2017-2018. Likely evidence that SARS-CoV-2 existed prior 2019. But with evidence also of gain-of-function stuff, who knows.

It's so suspicious how different they both are -- its origin raises some eyebrows as well.
