I think considering WA1 basal to WH04 is appropriate based on that single difference

In context

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

We have always used WH04 as the root -

WA1 may be a more appropriate one - firmly placing the start of the pandemic in the United States :wink:

Question is do we consider that WA1 (or more likely a Chinese genome such as hCoV-19/Fujian/8/2020) is basal to WH04?

Out of curiosity, I also checked WH1-4 since they had those super funky ENA entries (still do.... SAMEA6507890 -SAMEA6507893) - WA1/WH04 basal to those as well. [shared file(s): 2020.12.06_early-genomes.geneious]

(and I'd say ancestral here, since we have all the other genomes we can compare to)

I think we know that WA1 travelled from Hubei (need to check) so that places the WA1 haplotype in Hubei

Yup.
