Losing this factor may have limited the ability of neural crest cells to form cell types found in jawed vertebrates (animals with spines) that make up the head and jaw skeleton. The study will be ...

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 ...

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 ...

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 ...

Did you know that your knees, hips, and fingers all rely on the same type of joint that evolved hundreds of millions of years ...

WASHINGTON (Reuters) - Let's face it. It's easy to take for granted that mammals, birds, reptiles, amphibians and fish - vertebrates just like people - have a face. But it has not always been the case ...

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 ...

The alligator gar, and other gar species, are “living fossils” that it shows little species diversity or physical differences from ancestors that lived tens of millions of years ago. Credit: Solomon ...

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 ...
