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 ...

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 ...

During the course of evolution, the mammalian cranio-mandibular secondary joint—formed by the dentary condyle and the squamosal glenoid fossa, which replaced the reptilian articular–quadrate ...

I first read Lulu Miller’s Why Fish Don’t Exist in 2024. Interspersed with her personal exploration of finding purpose, ...
