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

Find out how joints facilitate movement, from humans to sharks, and the evolutionary history of these remarkable structures.

After the invention of whole-genome sequencing, we now know the sequences that make up an entire organism. Now what do they mean? To answer that, we turn back to linkage mapping in model organisms.

Humans have been selectively breeding cats and dogs for thousands of years to make more desirable pets. A new startup called ...

Jawed vertebrates known as gnathostomes appear to be the first creatures with the synovial joints, according to Shubin. These ...

Can a single protein-encoding gene determine whether a vertebrate embryo develops normally? Yes, according to Osaka Metropolitan University researchers, who found that suppression of Pcdh8 is ...

The Arctic is changing, and scientists and residents alike are interested to understand both the reasons for and impacts of these changes, including how it’s affecting fish populations that Alaskans ...

Humans who eat fish that have eaten smaller aquatic life ... They then injected the embryos of these creatures with a pair of enzymes, MerB (organomercurial lyase) and MerA (mercuric reductase ...

The ability of our skeletons to move with both flexibility and stability can be traced back to ancient jawed fish. Scientists ...
