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

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 ...

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

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 ...

Successful reproduction presents a fundamental evolutionary paradox: the immune system must tolerate genetically foreign sperm and embryos while maintaining ...

A major fossil discovery in Canada sheds new light on the development of the earliest vertebrates, including the origin of jaws, the first time this feature has been seen so early in the fossil record ...

The fossil turned out to be a hatchling of a crocodile-like creature, and it suggests, according to a new study, that early animals did not use metamorphosis to evolve to dwell on land ...

New fossil evidence is overturning a long-held assumption about how vertebrates first transitioned from water to land. The hatchlings of three different animals related to the earliest land-goers show ...

A rapid climate collapse during the Late Ordovician Mass Extinction devastated ocean life and reshuffled Earth’s ecosystems. In the aftermath, jawed vertebrates gained an unexpected edge by surviving ...

In the limestone ranges of Western Australia’s Kimberley region, near the town of Fitzroy Crossing, you’ll find one of the world’s best-preserved ancient reef complexes. Here lie the remnants of ...

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

Because we’re a member of the group, it’s easy to see vertebrates as the pinnacle of evolution, a group capable of producing bats, birds, and giant whales in addition to ourselves. But when they first ...
