A 400-million-year-old jawed fish fossil found in the Arctic, Romundina gagnieri, could be a key link in the evolution of ...

The study of early vertebrates provides an essential window into the evolutionary processes that shaped modern biodiversity. Fossil discoveries spanning the Silurian to Devonian periods reveal a ...

Add Yahoo as a preferred source to see more of our stories on Google. After an ancient extinction killed about 85% of marine species, survivors in isolated refuges helped jawed vertebrates diversify ...

The lower jaw - a vital component of the vertebrate feeding apparatus - has been a key element in their ecological experimentation and adaptation. Looking ahead, the team plans to delve deeper into ...

Newly discovered fossils, belonging to the mammal-precursor species Brasilodon quadrangularis and Riograndia guaibensis, offer critical insights into the development of the mammalian jaw and middle ...

Ancient viruses have really gotten on our nerves, but in the best of ways. One particular retrovirus — embedded in the DNA of jawed vertebrates — helps turn on production of a protein needed to ...

Researchers report February 15 in the journal Cell that ancient viruses may be to thank for myelin—and, by extension, our large, complex brains. The team found that a retrovirus-derived genetic ...

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 ...

Synovial joints, the lubricated cavity that lets the bones in our shoulders, knees, and elbows slide smoothly against each other, provide freedom of movement to all vertebrates. Scientists have known ...
