well, the pesticide resistance is at least an argument as opposed to steve and ians assertions and attempts at belittling.
i have come across this before and i dont have time to look up stuff right now but a few interim observations.
1 the headline might say it is evolution but there is unlikely be anything suggesting any change other than an advantageous one to that organism.
2 this is probably more correctly natural selection in operation.
something switched off in the genes maybe that rendered a survival advantage probably.
3   assuming that to be the case it is devolution, not evolution [at least in the GTE understanding .evolutionists often equivocate natural selection with the GTE ],though i accept that this is not always deliberate deception.
thanks anyway for a specific argument.maybe you would like to tackle some of mine that steve dodged
