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

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 ...

Scientists analyzing 443-million-year-old Scottish fossils have uncovered the early evidence that some of the first groups of vertebrates possessed surprisingly advanced eyes and traces of bone, ...

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 ...

Vertebrate morphology exhibits remarkable diversity, reflecting a complex interplay of developmental processes, genetic regulation and environmental pressures. This variation arises from a combination ...

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 ...

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 ...

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, and shallow seas shrank fast.
