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.

Experts have used CT scanning techniques to build up the first 3D pictures of these creatures, which are some of the earliest vertebrates (animals with backbones) in which the mouth is fossilized.

In the past, various researchers have placed yunnanozoans into multiple clades, including cephalochordates (a clade of rudimentary invertebrate marine animals), hemichordates (considered to be a link ...

All chordates, such as vertebrates, eel-like lancelets, and tunicates, or sea squirts, at some point in their lives have a flexible, rod-shaped nerve structure called a notochord in their backs. A ...

The sympathetic nervous system, which enables the fight-or-flight response, was thought to be present only in jawed vertebrates. Analysis of a jawless vertebrate suggests that this system might be ...

The efficient architecture of our joints, which allows our skeletons to be flexible and sturdy, originated among our most ancient jawed fish ancestors, according to a study published in the open ...

Researchers have attempted to decode the flying style of ancient pterosaurs — the earliest vertebrates to develop powered ...

Sensory features on the armored exoskeletons of ancient fish may be the reason why humans have teeth that are sensitive to cold and other extremes.

A large, crocodile-like animal that lived more than 340 million years ago was one of the earliest vertebrates to have a fast-growing phase in its youth. Altered gut microbiome linked to fertility ...
