Researchers have traced cell origins critical to vertebrate evolution by studying a group of primitive, bloodsucking fish called lampreys. When you purchase through links on our site, we may earn an ...

Many spine-bearing creatures, or vertebrates, have a curious bit of tissue deep in their brains called the pineal gland. It ...

What do we have in common with fish, besides being vertebrates? The types of joints we (and most vertebrates) share most likely originated from the same common ancestor. But it’s not a feature that we ...

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 ...

Immunostaining depicts collagen-2 (cyan) and nucleus (magenta) at the articulation in the little skate embryo's pelvic joint. Synovial joints are a key feature of most vertebrate skeletons, providing ...

Scientists from UK have used a synchrotron in USA to investigate ancient vertebrate fossils. The remains revealed surprisingly complex eyes.

Long before humans evolved, a small eel shaped creature swimming in ancient seas carried eyes that look strikingly familiar.

Yara Haridy, an evolutionary biologist at the University of Chicago, likes to stun people by telling them that our skeletons evolved from a jawless fish. “Much of what we have today has been around ...

A new study reveals that the sensitivity of teeth, which makes them zing in a dentist's chair or ache after biting into something cold, can be traced back to the exoskeletons of ancient, armored fish.

Jawless, bloodsucking fish could help us understand how humans and all other vertebrates evolved, scientists say. Turns out, lampreys — notable for their lack of jaw and generally terrifying ...
