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 ...

A research team led by Profs. ZHU Min, LU Jing, and ZHU You'an from the Institute of Vertebrate Paleontology and ...

Reef fish in different oceans often develop similar color patterns because evolution explores the same set of biological possibilities.

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.

In Lake Malawi, hundreds of species of cichlid fish have evolved with astonishing speed, offering scientists a rare opportunity to study how biodiversity arises.

While there is a common belief that the evolution of humans can be traced back to fishlike vertebrate ancestors, pinpointing the origins of bony fish — a key group in this evolution — remains ...

Beneath the surface of eastern North America are countless freshwater caves. Deep, dark, and closed off from the surface, these landforms are difficult to study and difficult to date, with their ages ...

A research team traveled to South Africa’s Umzimkhulu River in 2017 with a specific mission: find surviving pockets of the Maluti redfin minnow, a species declared extinct after introduced trout ...

Fish evolution is so strange that it's given us species that can count, change color by "seeing" with its skin and even fish that can "sing." But sea robins in the family Triglidae are some of the ...

Chinese paleontologists have discovered the world's oldest complete bony fish fossils, dating back 436 million years ...
