A research team led by the Universitat Autònoma de Barcelona (UAB) has revealed how the genome is reorganized in 3D during ...

What did the very first complex vertebrate brain look like? To find out, scientists turned to an unlikely time traveler: the ...

"It took 10 people over a week just to find this one tiny 10-millimeter adult." ...

A new study constructs the first 3D single-cell brain atlas of the lamprey, uncovering the 450-million-year-old molecular ...

Scientists once thought that humans must have 2 million genes to account for all our complexity. But since sequencing the human genome, researchers have learned that humans only have about 19,000 to ...

A better understanding of neuroimmune communication is crucial for identifying conserved and divergent mechanisms across ...

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 ...

A simple physical mechanism that can be assimilated to folding, or buckling, means that an unformed mass of cells can change in a single step into an embryo organized as a typical vertebrate. Thanks ...

Early vertebrates such as myllokunmingids were small and lacked effective defense mechanisms compared to the large predators ...

The discovery of embryos in certain fossil fishes not only shows that internal fertilization and live birth evolved early in vertebrate history, but also raises questions about the origin of jawed ...
