Sorry, Calandale, but you're wrong again. Evolutionary pressure can change the mutation rate. Google is your friend.
As for the rest, I guess you should read my earlier reply again, and 4AD's, for that matter. He provided links where I just can't be arsed.
You're putting words in my mouth (as was done with Eclaire). I NEVER stated there was no change in the rate.
4AD's links also did not address a damned thing about why mutations evade defenses - which is fucking elementary genetic selection.
I doubt you'd find research that deals with this in over a century. And that was the only thing I was talking about.
There ain't a thing we can do about it either. No vax? Post-infection immunity will cause the same circumstances.
We're all talking past one another here. You (and 4AD) are objecting to shit I never claimed, based upon your own preconceptions.
Although it's harder to tell with you - but what you said doesn't make a bit of sense in context, so you might just be an idiot.
I'm giving you the benefit of the doubt that it's your laziness and tribal affiliation here at play.
