Strange sea creatures called ctenophores have a fused nerve net where scientists expected to see synapses. Did they evolve their nervous system separately from other animals? When you purchase through ...

A new study has rewritten the conventionally understood evolutionary history of certain ion channels -- proteins critical for electrical signaling in the nervous system. The study shows that the ...
