The vertebrate body plan emerged in concert with extensive changes to anterior chordate morphology, including assembly of a craniofacial skeleton, expansion of the anterior neuroepithelium into a ...

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, ...

There may be twice as many vertebrates on the planet as previous estimates claimed, according to a new study published in the journal Proceedings of the Royal Society B: Biological Sciences. That's ...

Scientists once thought that humans must have two million genes to account for all our complexity. But since sequencing the human genome, we've learned humans only have about 19,000 to 25,000 genes - ...

Vertebrates produce diverse proteins from single genes, unlike invertebrates. This protein diversity helps vertebrates develop complex organs and cell types. University of St Andrews research offers ...

During this time, collection visits will be available by appointment and other special access requests will be considered on a case-by-case basis. Please email cumuseum@colorado.edu for more ...

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 ...
