The conservation of genome regulatory elements over long periods of evolution is not limited to vertebrates, as previously ...

Scientists from the UAB and Iowa State University have generated the genome assemblies of two hidden-neck turtles, unpublished until now. The results, which revealed a new three-dimensional structure ...

A fish thought to be evolution’s time capsule just surprised scientists. A detailed dissection of the coelacanth — a 400-million-year-old species often called a “living fossil” — revealed that key ...

Hundreds of millions of years ago, jawless fishes swam Earth’s seas, their brains protected on the outside by armored skin, and on the inside by plates made of cartilage. Scientists are still piecing ...

Corticoid receptors, encompassing both glucocorticoid and mineralocorticoid receptors, are pivotal to the regulation of physiological processes across vertebrates. These receptors have evolved through ...

In five cases where vertebrates evolved monogamy, the same changes in gene expression occurred each time. In many non-monogamous species, females provide all or most of the offspring care. In ...

One of Earth’s earliest mass extinctions wiped out most ocean life during a sudden global ice age. From the ruins, jawed vertebrates survived, diversified, and transformed the course of evolution.

About 445 million years ago, Earth’s oceans turned into a danger zone. Glaciers spread across the supercontinent Gondwana, ...

Ancient viruses have really gotten on our nerves, but in the best of ways. One particular retrovirus — embedded in the DNA of jawed vertebrates — helps turn on production of a protein needed to ...
