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

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 ...

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 ...
