"Rambaut _et al._ (2020) suggest that viruses from the clade labeled "B" in Figure 4 may just "happen" to have been sequenced first, but that other SARS-CoV-2 sequences are really more ancestral as implied by phylogenetic rooting." Uhhh Rambaut is right about this...

In context

A single line often inverts meaning once you see what it answers, so neighbouring messages are always shown.

```But the earliest known SARS-CoV-2 sequences, whichare mostly derived from the Huanan Seafood Market, are no-tably more different from these bat coronaviruses than othersequences collected at later dates outside Wuhan.``` This is incorrect - WA1 is from Wuhan

So it is they are notably (2 or 3 mutations) more distant from RATG13 than other viruses in Wuhan at the same time

Yes - he's got WA1 in the mix, but yes definitely WA1 early Wuhan for sure. I'm thinking Jesse making much ado about nothing - it's lineage A going to lineage B with WA1 from Wuhan ancestral.
