In two deposits in China, paleontologists dug up remains that suggest jawed fish are tens of millions of years older than previously known. Five newly discovered jawed fishes including ...

But it’s not a feature that we share with all vertebrates. Humans, other land vertebrates, and jawed fish have synovial joints. The lubricated cavity within these joints makes them more mobile ...

The efficient architecture of our joints, which allows our skeletons to be flexible and sturdy, originated among our most ancient jawed fish ancestors, according to a new study. The efficient ...

The diversity of jawed-fish remains from the Devonian period (419 million to 358 million years ago) — the Age of Fishes — suggests an evolutionary history that extends deep into or even before ...

This implies that this feature came from the ancestors of jawed vertebrates. "The origin of mobile joints in our fish ancestors enabled them to move about and feed in new ways. This study shows ...
