An essential component of animal nervous systems"”sodium channels"”evolved prior to the evolution of those systems, researchers from The University of Texas at Austin have discovered. "The first nervous systems appeared in jellyfish-like animals six hundred million years ago or so," says Harold Zakon, professor of neurobiology, "and it was thought that sodium channels evolved around that time. We have now discovered that sodium channels were around well before nervous systems...

Improvement in brain electrical signaling is critical both for vertebrate evolution and for preventing epileptic seizuresStudies at the University of Pennsylvania School of Medicine on brain electrical signaling offer a fresh perspective on vertebrate evolution, provide additional evidence supporting Darwinian views of evolution, and may also lead to more effective treatment of epileptic seizures in infants. Researchers discovered how evolutionary changes produced a series of improvements in...
