They have evolved a huge range of body sizes. Our study shows that sturgeon are evolving very quickly in some ways. "Sturgeon are thought of as a living fossil group that has undergone relatively slow rates of anatomical change over time. According to National Geographic, the lake sturgeon, a species in the same family, is the oldest and largest native fish species in the North American Great Lakes region.įor a long time, scientists believed that the sturgeon was like a “living fossil,” almost unchanged throughout its long history, but a 2013 study by the University of Michigan found that they were “one of the fastest-evolving fish on the planet.” Fish and Wildlife Service, the sturgeon predates many fish species, and can survive in many environments, including subtropical to subarctic waters. The sturgeon first appeared in fossil records around 200 million years ago.
