Why does a Caribbean angelfish sometimes resemble its Indo-Pacific cousin, even though they have never lived in the same ocean? Why do coral reefs harbor such a wide range of stripes, spots and ...

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

The Amazon molly is an evolutionary enigma: an all-female fish that reproduces by cloning itself. Because it doesn’t mix its DNA with a mate’s, Darwinian logic holds that harmful mutations should pile ...

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

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

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 trade-off between tooth size and jaw mobility has restricted fish evolution, Nick Peoples at the University of California Davis, US, and colleagues report in the open-access journal PLOS Biology.

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 ...

Scientists discovered some of the oldest bony fish fossils in China. The fossils explain the early history of animals with backbones.

Most mammals wear coats of brown, black, and gray, while parrots flash brilliant reds, reef fish shimmer in electric blue, and chameleons shift between greens and golds. This disparity is not random.

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