It's a good one. We could surmise that following 1600 greater
communication and the printing press could have retarded such
changes. Does anyone know how the interval 800-1600

Outrageous. But is it outrageous enough? :-)
If it was parallel to Clark's theory, then the richer classes
would be infiltrating the poorer classes with their genes,
and we would expect tendencies towards differential
pronunciation among classes. While in England there
was such a differential between Anglo and French, surely
the same thing was not occuring in lockstep on the continent.
So what on Earth could be the mechanism? After all, we
must have differential selection at work, I cannot think of
any effect (outside of science fiction) that would cause
those skilled at a certain kind of pronunciation to have
Except, of course, fashion. Sexual selection could indeed
do it. But then, as is so often the case, why not lay the
whole phenomenon at the feet of fashion. That is, fashion
might as well be invoked in explaining the vowel shift in
the first place.
