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 fish thought to be evolution’s time capsule just surprised scientists. A detailed dissection of the coelacanth — a 400-million-year-old species often called a “living fossil” — revealed that key ...

The coelacanth is known as a "living fossil" because its anatomy has changed little in the last 65 million years. Despite being one of the most studied fish in history, it continues to reveal new ...

Digital reconstruction of tiny, 400-million-year-old jawless fish shows how traits for evading predators later gave rise to hunters A fossil the size of a fingernail is rewriting the opening chapter ...

Two new studies add to the evidence that human activity, from fishing to urban development, is driving the evolution of wild animals. By Emily Anthes Call it the case of the incredible shrinking cod.

How did digits evolve? While it is clear that they derive from genetic programs already present in fish, their precise origin remains a matter of debate. An international team led by the University of ...

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 ...
