The old classic fast-sexual is a bag full of fruit flies. I recall driving and listening to the CBC back in the 90s. Apparently at that time, there had been fruit flies found which could metabolize DDT. It wasn't population wide, but obviously enough had that mutated capability for it to be discovered. I wonder when that first evolved? Hard to say, but it must have been years before? And wide-spread DDT use started in the 50s. But of course, fruit flies can reproduced + hatch every week or two? Hmm, interesting speculation here: https://www.eurekalert.org/news-releases/874322 https://www.eurekalert.org/news-releases/874322
