RE: [asa] Example of fast evolutionary change

Seems to me it's a little early to conclusively declare victory for the male
butterfly's rapid evolution, since it was only last year that the large
increase in population was discovered. What about next year, or 5 years
from now? Was it a temporary increase which will be wiped out in a few
years? Was it coincidentally a bad year for the parasite? Nevertheless, it
is interesting to ponder.
