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Scientists from the UAB and Iowa State University have generated the genome assemblies of two hidden-neck turtles, unpublished until now.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 ...

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 ...

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 ...

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.

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

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

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 ...

Why do you have five fingers? Why not ten, or twenty, or one? Why do so many animals have five fingers? Five seems to be the perfect number for most hands. Oddly, the first vertebrates to come onto ...

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 ...
