A stude at the University of California, Davis has recently revelaed a fish that has evolved against water pollution. They are found in harbors in the East Coast where there has been a mixture of highly complex industrial pollutants since the 1950's. This species is known as the Atlantic Killifish. They have rapidly evolved to be 8,000 times more resistant to water pollutants than other fish. The reason they have been so quick to evolve is because of thier incredibly high genetic diversity. It is great than that of even humans. While this is intersting, we should not get our hopes up of evolution catching up to the sixth mass extinction we have brought because the majority of species do not have nearly as high of genetic diversity than these fish. While these fish have no commercial value, the serve as an important food source to fish that do have commercial value. This is a perfect example of the term, "Nature always finds a way." It is incredibly interesting that these fish have evolved in the last sixty years to become resistant of heavily polluted water. While we cannot expect species to evolve at such a rate, this should be a prime incentive to push for genetic diversity and restory endagered species populations so that they become more resistant to radical change brough to their environment by people. This research can also lead to further exploration of how gene pools can influence a populations resistance to change or ability to adapt to change. https://www.sciencedaily.com/releases/2016/12/161208143334.htm
