   Did you see this: https://www.biorxiv.org/content/10.1101/2021.02.13.431090v1.full.pdf+html

   I've not read it carefully yet, but interesting to see the adaptive changes in ORF1ab as well. They are dead right thatdN/dS is pretty rubbish when you have fixed mutations.

   Yeah, just saw it too - pretty interesting. And yes, "A" is totally unique to SC2 there

   I'm in...sorry, just catching up this thread now.

   it's nicely spotted, since it's the only mutation unique to SC2 in the RBD - we should have picked this up earlier. Iwonder if H519 does something interesting too.

   519 is "H" in SC2, but N in almost all other sequences - the only other deviation is K in the P378 pangolin, although that is a pretty bad sequence, so might not be real.

   No one thinks about fixed changes: nicely blows-up the idea that SARS-CoV-2 was perfectly adapted to humans at the outset.

   Well, actually, this supports being perfectly adapted to humans :wink:. A in that position was fixed from the get go.
