Learn more about the amblyopsid cavefishes, the eyeless fish that inhabit the caves of eastern North America, whose evolution can uncover the age of difficult-to-date cave systems. This is the Hoosier ...

A study published in the Nature journal alters how the evolution of fish has been historically understood. Fossilized fish and other sea creatures have often been pivotal in new scientific discoveries ...

Fossils in Brazil indicate a more complex evolutionary history for ray-finned fish brains than previously anticipated, according to new research. The researchers not only found well-preserved brains ...

Why are there so many species of coral reef fish? According to a new study, it’s because about 50 million years ago, some fish figured out how to bite food from hard surfaces. Evolution doesn’t ...

Atlantic and Baltic herring are typical plankton-eating fish of central importance for the northern Atlantic Ocean and Baltic Sea ecosystems. A new study published in Nature Communications led by ...

Some fish come onto the land to hunt or move around. Typically, this behavior happens at nighttime, as seen in eels, for instance. In the new study, researchers have found that such amphibious fishes ...

3D rendering of the tiktaalik, an extinct walking fish. Dotted Yeti/Shutterstock When you think about human evolution, there’s a good chance you’re imagining chimpanzees exploring ancient forests or ...

Complex teeth with multiple cusps in an African cichlid fish. The cichlid fish of Africa's Great Lakes have formed new species more rapidly than any other group of vertebrates. A new study shows that ...

Why do you think giraffes have such long necks? It’s a question that has perplexed scientists for years. Do you think giraffes have long necks to reach food in high places? Maybe you are onto ...

It's not what you do, it's how readily you do it. Rapid evolutionary change might have more to do with how easily a key innovation can be gained or lost rather than with the innovation itself, ...
