Fruit flies on three continents appear to be genetically adapting to a hotter world. Until now, most species' adjustments to global warming have involved shifting population distributions or changing the time of breeding and migration -- physiological changes associated more with temperature and season length than genetics. Those species are still vulnerable to extinction as temperatures rise. Now ... (Full article: 202 words)
