JE:-
"A critique of [my] proposed experiment"?
To suggest that I have "deleted variation"
within my experiment belies belief. All such a
"criticism" suggests is that you do know what
you are talking about, yet you represent yourself
as a professional in the field with a PhD to hapless
sbe readers.
I repeat: it is IMPOSSIBLE to delete random
processes from any natural population. All you
can do is delete NON random processes. If you
wish to continue to argue that it is possible
to delete random processes from a natural
population please describe how to achieve
such an impossible event or apologise
to sbe readers for providing such
Mad Hatter nonsense as a valid criticism.
