To @Andrew Rambaut point above. I'm pretty sure there has been a global shift in the fitness landscape. I'm not too sure where the major selection is at the population level or the individual level or BOTH. However, I do think that the mutations at nsp12 P323 are contributing mightily to the volatility. I'm just shaking my head in disbelief. Like ascreaming read flag this amino acid is literally sitting in the groove of the RdRp complex. It surely has to affecttranscription fidelity. A deletion in nsp8 also may be a factor.

In context

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

Same feeling I got when I saw the PRRA....

Looks like it showed up early around about the time of the first DouG sightings.

What's the coordinates of that mutation in ORF1a space Bob?

I think it's C14408T P4715L.
