Discover the latest articles and news in related subjects. In this Review, we examine the morphological and genetic features that distinguish vertebrates from other chordates, focusing on cells and ...

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 ...

The cradle of vertebrate evolution was limited to a zone of shallow coastal waters, no more than 60 meters deep. In those waters, fish — the first vertebrates — appeared roughly 480 million years ago, ...

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 have long puzzled over the gap in the fossil record that would explain the evolution of invertebrates to vertebrates. Vertebrates, including fishes, amphibians, reptiles, birds, mammals, ...

The hypothalamus is involved during the coordination of neuroendocrine functions in vertebrates and their evolutionary origin can be described using integrated transcriptome or connectome brain maps ...

A mass extinction of fish 360 million years ago hit the reset button on Earth's life, setting the stage for modern vertebrate biodiversity, a new study reports. The mass extinction scrambled the ...

Charles Darwin proposed that evolution is driven by gradual variations in organisms that have a survival advantage in a changing environment. But University of Maryland evolutionary biologist Karen ...
