The earliest known vertebrates had four eyes—and they worked a lot like ours do, new research suggests
Many spine-bearing creatures, or vertebrates, have a curious bit of tissue deep in their brains called the pineal gland. It ...
Every mammal, every fish, every vertebrate (creatures that have a spine) has two eyes. It’s been that way for millions and ...
Scientists analyzing 443-million-year-old Scottish fossils have uncovered the early evidence that some of the first groups of ...
The study of early vertebrates provides an essential window into the evolutionary processes that shaped modern biodiversity. Fossil discoveries spanning the Silurian to Devonian periods reveal a ...
Vertebrate morphology exhibits remarkable diversity, reflecting a complex interplay of developmental processes, genetic regulation and environmental pressures. This variation arises from a combination ...
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 ...
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 ...

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.
Bucknell University Professor Jeffrey Trop, geology & environmental geosciences, is one of the recipients of a National Science Foundation (NSF) $148,000 collaborative grant supporting research that ...
About 445 million years ago, Earth’s oceans turned into a danger zone. Glaciers spread across the supercontinent Gondwana, ...
