What an interesting shift to anyone familiar with watching a shell game
artist fleece a mark. First it's a mutation you ask for, then it's an
*adaptive* mutation. Well, GEE, how'd the pea get under THAT shell? Aw, I'm
sure your attention just wandered. You'll get it right NEXT time, for
SURE...
So the next move in this little game is that someone brings up those famous
moths getting selected for changes in shade as pollution built up and then
declined in the British Isles, with the _presumption_ that one or the other
color was a mutation WRT its opposite, at which point you tell us that's
just selection pressure applied, not to mutation, but to "normal variation"
or a subspecies or recessive gene or some such--leaving the question of how
either the recessive or the dominant trait came into being if not by
mutation. Since we didn't have perfect information (genome data), how can
we tell?
Give it a rest. You're not the only detective here--but you still seem to
live under a bridge.
