Just tried to say that I don't believe that any sensible person would
consider that any form of natural selection can go on at the molecular level
(the level at which genes exist as molecular part/part-sequences of the
DNA-molecule) other than possibly that at some very early era of
self-replicating molecules some such potentially phenotyping parts (bases)
proving more stable against adverse physical pressures/influences (intrinsic
and extrinsic such) than "differently spelled" other such molecular parts.

[It is to that era of 'our' evolution that TomHendricks's thoughts about
"heat moderation" (Opportunity type pressures in the direction of such
"moderation", and heat-Adversity type pressures against insufficient such
moderation) might be rather well fitted.]

The way I see it, natural selection at that level, and at least in that
particular sense, has been finalized this very long time ago.
