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 ...

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 ...

Experts have uncovered the earliest known example of a fish with extra teeth deep inside its mouth—a 310-million-year-old fossilized ray-finned fish that evolved a unique way of devouring prey.

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 ...

The deep ocean remains largely unexplored, despite containing a large portion of the living organisms and animals on Earth. Among the many creatures populating the deep-sea are so-called Cyclothone, ...

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 ...

Whole skeleton of Dipterus, an extinct lungfish from the middle Devonian period. Specimen (UMMP 16140) from the University of Michigan Museum of Paleontology. ANN ARBOR—If you're reading this sentence ...

The skulls of tetrapods had fewer bones than extinct and living fish, limiting their evolution for millions of years, according to a latest study. The skulls of tetrapods had fewer bones than extinct ...

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, ...
