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 ...

Fish exhibit considerable biodiversity in genetics, morphology and behaviour that has been shaped by environmental factors such as habitat variation, climate fluctuations, and geological events. By ...

Researchers identified a new freshwater fish species in South Africa after years of genetic testing and analysis.

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 June 24 th in the open-access journal PLOS ...

A search for a fish lost to extinction led to a brand-new species hiding in a South African river.

Life reconstruction of Platysomus, with open mouth showing toothplate on the floor of the mouth supported by gill bones. ANN ARBOR—A University of Michigan researcher helped identify the earliest ...

What do we have in common with fish, besides being vertebrates? The types of joints we (and most vertebrates) share most likely originated from the same common ancestor. But it’s not a feature that we ...

If you're reading this sentence, you might have a fish to thank. Fish were the first animals to evolve jaws. They use their jaws primarily to eat, but also for defense, as tools—such as to burrow or ...

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 ...

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, ...
