While the exterior of vertebrate bodies appears bilaterally symmetrical, internal organ positioning and morphology frequently exhibit left-right (L-R) asymmetries. In several vertebrates, including ...

A novel system developed by Janelia researchers that chases larval zebrafish around an arena with predator robots is enabling ...

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.

A team of researchers has outlined a new approach for better understanding the depths of animal consciousness, a method that ...
