Reef fish evolved the ability to feed by biting prey from surfaces relatively recently, a UC Davis study shows. The innovation has driven an explosion of evolution in reef fish. Image shows a rainbow ...

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 ...

Along the murky bottom of the Amazon River, serpentine fish called electric eels scour the gloom for unwary frogs or other small prey. When one swims by, the fish unleash two 600-volt pulses of ...

An ancient, well-preserved fish brain analyzed recently by University of Michigan scientists could unlock new discoveries about evolution and the formation of fossils. The brain, which the university ...

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, ...

A fish thought to be evolution’s time capsule just surprised scientists. A detailed dissection of the coelacanth — a 400-million-year-old species often called a “living fossil” — revealed that key ...

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 ...

The ancient coelacanth, which has existed for some 419 million years, never stopped evolving despite its reputation as a "living fossil." A new discovery reveals that it evolved faster when plate ...
