A 400-million-year-old jawed fish fossil found in the Arctic, Romundina gagnieri, could be a key link in the evolution of ...

Scientists have uncovered an unexpected genetic shift that may explain how animals with backbones first emerged and became so diverse.

Learn how increased protein diversity in signaling genes may have helped drive the shift from invertebrates to vertebrates, ...

New pieces have been added to the puzzle of the evolution of some of the oldest fish that lived on Earth more than 400 million years ago. In two separate studies, experts in Australia and China have ...

New research from the University of St Andrews has discovered a crucial piece in the puzzle of how all animals with a ...

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 ...

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 ...

Many spine-bearing creatures, or vertebrates, have a curious bit of tissue deep in their brains called the pineal gland. It ...

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 ...

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