The Atlantic killfish, like the one above, is special because it has very high levels of genetic variation, higher than any other vertebrate. The more genetic variation the faster evolution can act upon that creatures. The fish were taken from a multitude of different sites, including Massachusetts, New Jersey, Connecticut, and Virginia. Their test also concluded that their high levels of genetic variation were not due to the polluted enviorment, instead they were already present in the fish's genome. The Atlantic killfish has had the ability to adapt very quickly to changing enviorments. The study lay the frame for future research that can figure out which genes are used to deal with the chemical change. (University of California- Davis).
