Fish Quickly Adapt to Lethal Levels of Pollution

Evolution is allowing some urban fish to survive in a lethal, human-altered environment, according to new results published in the journal Science. While environmental change is outpacing the rate of evolution for many other species, Atlantic killifish living in four polluted East Coast estuaries turn out to be remarkably resilient. These fish have adapted to levels of highly toxic industrial pollutants that would normally kill them.
