Has anyone considered how easy it is for this behaviour to occur de
novo? If it is at low (but not vanishingly small) rate, it would be more
easily learned than invented, so the dynamics will be those of meme
spread; but if there is an interruption, it could easily reoccur.
Apparently the original thing started in several places, given the
advent of the new foil tops across many regions, in a fairly short space
of time. This is a bit like the way agricultural pests cross to crop
species actually (new niche appears out of the blue).
