Imagine a world where the boundaries between “fish” and “not-fish” blur, where the ancestors of birds and mammals once swam ...

Complex neural circuits likely arose independently in birds and mammals, suggesting that vertebrates evolved intelligence ...

A major event in vertebrate evolution was the transition from aquatic to terrestrial life, made possible by the emergence of ...

This story appears in the October 2017 issue of National Geographic magazine. From scales to feathers to fur, vertebrates clothe themselves in a dazzling variety of textures and hues. But ...

A fossil analysis suggests that the yunnanozoan, a wormlike fish that flourished around 520 million years ago, sported structures that were the precursors of the head and jaws of modern vertebrates.

In vertebrates, the skeleton of different regions of the body arises from different precursor cells. Researchers have now discovered that these skeletal cells do not just differ in their ...

The Paleontology Section continues to actively collect and conduct research on fossil vertebrates from the Cenozoic of the Rocky Mountain region.

Among them were the chordates, to which vertebrates (animals with backbones) such as humans belong. What sparked this biological bonanza isn't clear. It may be that oxygen in the atmosphere ...

Osaka Metropolitan University researchers review the evidence for individual face recognition in fish and speculate that face identification neural networks are both similar and widespread across ...

Segmentation is the term applied to the differentiation patterns of vertebrates and arthropods, in which serial repetition of similar anatomical modules creates a body axis. In vertebrates ...

A comparative study of vertebrate embryological development focusing on the morphological development (e.g., Differentiation of tissues, organs, and systems) of vertebrates. Evolutionary relationships ...
