Scientists have discovered a new species that lived more than 500 million years ago -- a form of ancient echinoderm that was ancestral to modern-day groups such as sea cucumbers, sea urchins, sea ...

Researchers at University of Tsukuba have identified a brain-like cluster of neurons in sea urchin larvae, traditionally considered lacking a brain, that regulates light-responsive behavior. The work ...
