According to the data considered by its authors—a team from the University of Sussex (UK) and Lund University ...

A research team led by Profs. Zhu Min, Lu Jing, and Zhu You'an from the Institute of Vertebrate Paleontology and ...

Earth’s vertebrate diversity may be far richer than anyone realized. A sweeping analysis of more than 300 studies suggests that for every known fish, bird, reptile, amphibian, or mammal species, there ...

After cold winters, invertebrates such as honeybees and paper wasps seem to disappear and then suddenly return in large ...

The findings suggest that the appearance of the vertebrate head skeleton ‘did not depend on evolution of a new skeletal tissue, as is commonly thought, but on the spread of this tissue throughout the ...

Scientists discovered some of the oldest bony fish fossils in China. The fossils explain the early history of animals with backbones.

Scientists may have been dramatically undercounting the number of vertebrate species on Earth. A large analysis of more than 300 studies suggests that for every recognized species of fish, bird, ...

Biologists have considered nearly every major taxon of animals as the key starting point for the evolution of vertebrates. We survey these ideas, many of which are no longer tenable in the light of ...

The neural crest is characterized by its origin in the CNS, its migratory behaviour and its ability to differentiate into many cell types (multipotency). Although all animals of the chordate phylum, ...

Researchers have elucidated the evolutionary origins of placodes and neural crests, which are defining features of vertebrates, through lineage tracing and genetic analysis in Ciona intestinalis, a ...

The origin of all living vertebrates just got more mysterious. Since the 1970s, many evolutionary biologists have considered an eel-like, deep-sea-dwelling creature called the hagfish to be the ...
