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

Jawless, bloodsucking fish could help us understand how humans and all other vertebrates evolved, scientists say. Turns out, lampreys — notable for their lack of jaw and generally terrifying ...

In your brain the right side controls the left half of your body and vice versa. We still aren't sure why this is, but some ...

The preservation of fossils of some of the oldest known vertebrates is so impressive that palaeontologists can not only count their eyes, but determine how they worked. The findings demonstrate that ...

Researchers at University of Tsukuba and their collaborators have conducted a comprehensive analysis of the olfactory receptor repertoire of the hagfish (Eptatretus burgeri), a jawless vertebrate.

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.

What do we have in common with fish, besides being vertebrates? The types of joints we (and most vertebrates) share most likely originated from the same common ancestor. But it’s not a feature that we ...

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 ...

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

During these waves of mass extinction, most vertebrate survivors were confined to refugia, or isolated biodiversity hotspots separated by large areas of deep ocean. In these zones, surviving jawed ...

Researchers have traced cell origins critical to vertebrate evolution by studying a group of primitive, bloodsucking fish called lampreys. When you purchase through links on our site, we may earn an ...
