A new fossil study by scientists challenges long-held ideas of fish evolution, revealing surprising insights into early ...

Coral reefs are home to a spectacular variety of fish. A new study by biologists at the University of California, Davis, shows that much of this diversity is driven by a relatively recent innovation ...

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 ...

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 ...

One of the most important, most mystifying moments in the history of the planet was the emergence of the first fish out of water and the evolution of those fish into the earliest land-living tetrapods ...

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 ...

When an Australian scientist uncovered an ancient-looking placoderm skull in the 1960s, he thought he'd cracked the code on an evolutionary mystery. This so-called 'platypus fish,' scientists had ...

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 ...

Big tidal ranges some 400 million years ago may have initiated the evolution of bony fish and land vertebrates. This theory is now supported by researchers who, for the first time, have used ...
