The fastest-evolving fish on the planet

U. MICHIGAN (US) — Often called “living fossils,” the prehistoric-looking sturgeon are actually evolving very quickly when it comes to body size.

“Sturgeon are thought of as a living fossil group that has undergone relatively slow rates of anatomical change over time. But that’s simply not true,” says Daniel Rabosky, assistant professor in the ecology and evolutionary biology at the University of Michigan and a curator of herpetology at the Museum of Zoology.
