Yeah, Alpha had the same mutation as Omicron too.
I'm not a virologist by any stretch of imagination. Mutations seem to come in bundles; I'm just surprised that, given typical PCR tests only test for three RNA fragments, that we don't see mutations that evade it.
The main evolutionary pressure on Covid in developed countries is Public Health clamping down on it like a ton of bricks. A variant that quietly evades PCR tests, self-isolation etc. is set up for life.
