      this is one thing I keep meaning to point out: not finding close SARS-2 relatives in the wild is not evidence against a natural origin, because any lab origin scenario *also* requires close SARS-2 relatives in the wildhttps://twitter.com/beyerstein/status/1404828329719500808 …

      Any lab origin hypothesis presupposes a natural origin of COVID (simple leak of wild virus), or of natural precursor viruses >99% similar to COVID to use as raw materials for serial passage or as chimeras.

      there is no remotely plausible scenario in which there aren't much closer relatives to SARS-2 than any currently known viruses that are circulating or have circulated in the past we do not have the ability to design a virus from scratch, we need wild viruses to steal from

      once we have isolates 99+% similar i think the question will already have been mostly answered tbh

      that's already as good or better than what we know for SARS-1, though in fairness we should probably put a lot more effort into this than we did into SARS-1

      I am not entirely sure, I should probably reread the paper but the numbers I saw were in the mid-90s that might have been across the whole genome though, maybe the segments that matched different parts of SARS-1 were higher?

          right, that's the paper just tricky to tell from their figures what the exact numbers are, definitely varies across the genome though some regions >98%, others in the low 90s
