If it is unlikely, then it is possible! But my point is not that a
random mutation might actually reverse, my point is that there is _no
preferred directionality_ to the process. Evolutionists try to come up
with random processes that can produce more complex proteins and
structures from simpler ones (climbing mount improbable), without it
seems, ever considering that the reverse path is just as possible in
every case and typically many many orders of magnitude more probable
(rolling down mount improbable).
The fact that we see E. Coli gain penicilin resistance and then loose
it again simply means that this micro-evolution variation is
reversible and thus not based on a random mutation process. This
conclusion can not be denied.
Sorry but I can see no reason why this effect cannot occur by a random
mutation processes? Some mutation can allow resistance and a different
mutation prevent it again. I don't know whether penicillin resistance
requires something to work, or requires something to be prevented from
working. But there are often many ways to "switch on" some gene to get
it working (eg by clobbering whatever is preventing it), and an infinity
of ways of breaking something to stop it working.
