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

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

In DNA, retrotransposons can move around and insert themselves into other parts of genomes with a kind of copy and paste mechanism. Most have lost this ability in humans, but they still make up a ...

Scientists from the UAB and Iowa State University have generated the genome assemblies of two hidden-neck turtles, unpublished until now.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 devastating ice age wiped out most marine life, yet new research reveals how this ancient disaster unexpectedly paved the ...

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 ...

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 ...

The cichlid fish of Africa's Great Lakes have formed new species more rapidly than any other group of vertebrates. A new study shows that the ease with which these fish can develop a biological ...

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