More information: Sharma N, et al. Synovial joints were present in the common ancestor of jawed fish but lacking in jawless fish. PLOS Biology (2025). DOI: 10.1371/journal.pbio.3002990 ...

Researchers were able to examine the fish in great detail using a powerful microscope. See what they discovered.

In a nutshell Synovial joints—the flexible, lubricated connections that allow smooth movement in our bodies—first appeared in the common ancestor of all jawed vertebrates but are absent in jawless ...

Researchers used powerful technology to analyse thousands of individual cells at once, considering which genes are active.

Human embryos briefly exhibit traits like tails and gill-like structures, revealing our evolutionary history and deep ...

Ancient fish had synovial joints, challenging the idea that flexible skeletons evolved on land. Fossils and modern fish show similarities.

“Humans and fish aren’t close evolutionary cousins,” Siek said. “We’re part of the same phylum called Chordata. We share a common ancestor. Those in Chordata have backbones. So, this ...

These joints are present in land vertebrates and bony fish, suggesting this feature had evolved in the common ancestors of these groups, but it remains unclear when in early vertebrate evolution ...

Researchers used powerful tech to analyse thousands of individual cells at once, considering which genes are active and how DNA is organised within each cell.

Today, the U.S. Department of the Interior announced that the U.S. Fish and Wildlife Service has finalized the transfer of 680 acres of land to the Bureau of Indian Affairs, where it will be held in ...
