New fossil evidence from China suggests that some of our vertebrate ancestors had four eyes. The study, published in Nature, ...

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.

The discovery shows that ancient vertebrates had a far more complex visual system than previously thought. The post Fossils ...

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 ...

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Scientists from the UAB and Iowa State University have generated the genome assemblies of two hidden-neck turtles, unpublished until now.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

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

Early jawless fish were likely to have used bony projections surrounding their mouths to modify the mouth's shape while they collected food. Experts have used CT scanning techniques to build up the ...

(CNN) — 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 ...

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