Study Finds on MSNScientists trace our flexible joints back to the jaws of ancient fishThe same joint architecture and developmental process found in human joints is present in sharks and skates, showing this biological design has remained largely unchanged for hundreds of millions of ...
Over the past 60 years, scientists have had success preserving the sex cells and embryos of humans, cattle, mice, and many other animals. Trying to freeze and thaw fish embryos, however, has been more ...
Ancient fish had synovial joints, challenging the idea that flexible skeletons evolved on land. Fossils and modern fish show ...
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.
Jawed vertebrates known as gnathostomes appear to be the first creatures with the synovial joints, according to Shubin. These joint cavities can be seen in cartilaginous fish such as skates or sharks.
Humans have been selectively breeding cats and dogs for thousands of years to make more desirable pets. A new startup called the Los Angeles Project aims to speed up that process with genetic ...
The ability of our skeletons to move with both flexibility and stability can be traced back to ancient jawed fish. Scientists ...
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 ...
One of the fish’s advantages is clear—literally. Because embryos are transparent and develop outside the mother’s body, scientists can manipulate genes to model human diseases and directly ...
Using fossils, embryos and genes, he reveals how our bodies are the legacy of ancient fish, reptiles and primates — the ancestors you never knew were in your family tree.
