Dear David,

I note you feel you are occupied "just pointing out [my] errors".
Although I would readily admit any errors I might have made it would seem I
cannot see you actually pointing out any. If I have to describe what it is
you are doing it would seem you fasten upon I word I use, you connect this
with a
random word you derive from an unknown source and off you go ...

Since you were kind enough to provide such a clear example I will use that
to set the record straight. I stated:
"It is like expressing human progress over the last millenia by measuring
individual body weight: this may be be useful data but presents only a small
part of the picture".
If one were to conduct a poll as to what constitutes "human progress over
the last millenia" one might get quite different answers, such as the
invention of the wheel, the agricultural revolution, the invention of the
printing press, the industrial revolution, instant coffee, automobiles,
computers, cell-phones, nintendo, etc but genetic change would not be high
on the list, perhaps not even in the top thousand.
Yet you blithely state "Measuring a change in allele frequency is not at all
like "measuring individual body weight" as you suggest. Human body weight is
largely a function of environment, not genetics."

Although I am sure you will take this the wrong way, I feel honor bound to
advise you, with all due respect, to confer with your doctor about your
medication.

As to gene expression it is clear you are hampered by some severe
misconceptions. The safe advice would be for you to refrain from commenting
on this topic. This is the more so since it would not be enough for you to
read a book on the topic. As I am sure you are aware re-education is much
harder than education. You would need to take a course on the topic to
straighten matters out, and this might come hard. You had better avoid it.
Sorry to be so blunt.

sincerely,
PvR
