Drift always happens in every
population all of the time without exception. This is not an opinion,
rather it is a necessary consequence of the finiteness of all populations.
It is selection that can come and go along with heritable variation for
fitness.

JE:-
I agree that "drift always happens in every population all of the time
without exception" and selection may not. However, unless Guy is prepared to
say _why_ he may end up misleading the reader. Note also that "heritable"
and "fitness" must be defined by him. I know of no definitions posted to sbe
by Dr Hoelzer for either of these key terms.

Drift remains ubiquitous only because it is a random process. NOTHING can
halt a random process. OTOH, selection was and remains, entirely a NON
random process. Therefore SELECTION MUST BE ABLE TO BE EMPIRICALLY STOPPED.
What Guy (and it appears almost everybody else here) have failed to
acknowledge is that selection can only be halted ONE WAY: maintain equal
Total Darwinian Fitnesses (TDF) per population. This means: allow the total
number of fertile forms reproduced into one population by each parent to
remain equal over as many generations as possible. The prediction is: all
evolution via the Darwinian NON random process will be stopped only allowing
RANDOM heritable change (drift and mutation) to continue. If the experiment
can be maintained long enough, drift and mutation without selection can only
_lower_ fitness to such an extent that it will no longer be possible to
continue the experiment.
