The Evolution of the Atlantic Killifish Greta Maneker

The article reports that a common fish in our area, the Atlantic Killifish, was able to adapt over only a few generations to survive in the polluted waters outside of the Diamond Alkali Superfund in Newark, NJ.

A biologist (Diane Nacci) and an evolutionary geneticist (Noah Reid) compared the genomes of 384 killifish and found a rare mutation that allowed some of the fish to survive in polluted waters. The fish that had this mutation survived and reproduced.

Scientists believe that this study could show that genetic diversity will help species survive the effects of climate change.

This article is noteworthy as it shows nature's ability to adapt and survive. However, this is just one example and cannot be relied on for other species or the rest of the world. What is required after this study is more research to discover how climate change is affecting species' genetic diversity and their evolution.

I chose this article because I found the evolution of the killifish interesting, as this is a fish that lives very close to Larchmont. Even in a place that would seem to not have much innovation in the fauna, a revolutionary adaptation is occurring! Learning about the environment directly around me is rewarding because I learn more about my surroundings, and thus appreciate them more.
