I think it's fair to say that the lineage that led to WA1 > WH04 is probably older than the lineage that led to Hu-1.And yeah - RmYN02.. :wink: That one is ancestral in those positions too

In context

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

Here's an alignment - it's pretty messy and some duplicates... [shared file(s): 2020.12.06_pango-bat-sars2_alignment.geneious]

Am I going mad - I just downloaded RmYN01 from GISAID and it is coming out as more divergent than RaTG13?

Yes

Doh. I was thinking of RmYN02

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]
