Against the Tide: A Fish Adapts Quickly to Lethal Levels of Pollution
December 9, 2016 07:24 AM - Kat Kerlin, UC Davis
Evolution is working hard to rescue some urban fish from a lethal, human-altered environment, according to a study led by the University of California, Davis, and published Dec. 9 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.
