Mudskippers break the rules of fish biology by breathing through their skin, walking on their fins and thriving on land where ...

During these waves of mass extinction, most vertebrate survivors were confined to refugia, or isolated biodiversity hotspots ...

Our sensitive teeth originally evolved from the "body armor" of extinct fish that lived 465 million years ago, scientists say. In a new study, the researchers showed how sensory tissue discovered on ...

A tiny fossil fish from Alberta is forcing scientists to rethink a story that has sat quietly in textbooks for decades. It is ...

Researchers have found that chunks of ‘flipped’ DNA can help fish quickly adapt to new habitats and evolve into new species, acting as evolutionary ‘superchargers’. Why are there so many different ...

A newly discovered 310-million-year-old fossilised fish is the earliest known example of one with extra teeth deep inside its mouth. The ray-finned fish found in Staffordshire evolved a "unique" way ...

Long ago, some saltwater fish adapted to freshwater — and in doing so, developed an extraordinary sense of hearing rivaling our own. By examining a 67-million-year-old fossil, researchers from UC ...

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 ...

It’s beginning to look like our success on land, and that of all tetrapods, from frogs to dogs to dinosaurs, was just a lucky side-effect of fish trying to stay fish. Eons is available to stream on ...
