The water-to-land transition stands as one of the most significant events in vertebrate evolution, giving rise to the two major groups of living land vertebrates-amniotes and lissamphibians-which ...

The adaptive immune system of vertebrates represents a major evolutionary innovation that underpins the capacity for antigen-specific recognition, immunological memory and refined regulation of host ...

Researchers report in the journal Cell that ancient viruses may be to thank for myelin—and, by extension, our large, complex brains. The team found that a retrovirus-derived genetic element or ...

The water-to-land transition stands as one of the most significant events in vertebrate evolution, giving rise to the two major groups of living land vertebrates—amniotes and lissamphibians—which ...

Assumptions that may seem self-evident are not always accurate when it comes to the evolution of vertebrate brains. Researchers at the University of Bayreuth have now demonstrated this by examining ...

A harlequin poison dart frog (Oophaga sylvatica) is pictured at the Tesoros de Colombia (Treasures of Colombia) sustainable farm in Nocaima, Cundinamarca department, Colombia, on July 9, 2024.

Within every muscle of every living species with a backbone, a protein called myosin tugs on a partner protein to generate a ...

A research team at Yunnan University has resolved a longstanding mystery regarding Earth’s earliest vertebrates, revealing ...

Vertebrates have extremely different brain sizes: even with the same body size, brain size can vary a hundredfold. As a rule, mammals and birds have the largest brains in relation to their body size, ...

Researchers report that ancient viruses may be to thank for myelin -- and, by extension, our large, complex brains. The team found that a retrovirus-derived genetic element or 'retrotransposon' is ...
