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

Learn how increased protein diversity in signaling genes may have helped drive the shift from invertebrates to vertebrates, reshaping how animals with a spine evolved. From frogs and fish to birds and ...

Analysis of a 458-million-year-old fossil fish reveals anatomical insights about the vertebrate skull and how skull organization evolved from that of ancestral early vertebrates to that of jawed ...

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.

New CU Boulder-led research finds that the traits that make vertebrates distinct from invertebrates were made possible by the emergence of a new set of genes 500 million years ago, documenting an ...

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 ...

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 ...

A tiny fossil fish, roughly 3 centimeters long and approximately 436 million years old, has been identified as the oldest ...
