We’re only in the early stages of 2026, and one massive change from last year may have already occurred: there may actually ...

There may be twice as many vertebrates on the planet as previous estimates claimed, according to a new study published in the journal Proceedings of the Royal Society B: Biological Sciences. That's ...

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

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

The earliest ancestors of all backboned animals, including humans, may have viewed the world with four eyes, not just two.

Learn how a second pair of eyes helped this 518-million-year-old fish evade predators.

Fossils of the prehistoric fish genus myllokunmingiid, more than 518 million years old, reveal that early vertebrates may have had four functional eyes. Researchers found that two large lateral eyes ...

The study has revealed unexpected and sex-specific effects of germline regulation on longevity and somatic repair in vertebrates. Contrary to classical evolutionary theories, it turns out that ...

New research from the University of St Andrews has discovered a crucial piece in the puzzle of how all animals with a spine—including all mammals, fish, reptiles and amphibians—evolved. In a paper ...
