Complex nerve-cell signaling traced back to common ancestor of humans and sea anemones

16 February 2015 — New research shows that a burst of evolutionary innovation in the genes responsible for electrical communication among nerve cells in our brains occurred over 600 million years ago in a common ancestor of humans and the sea anemone. The research, led by Timothy Jegla, an assistant professor of biology at Penn State University, shows that many of these genes, which when mutated in humans can lead to neurological disease, first evolved in the common ancestor of people and a group of animals called cnidarians, which includes jellyfish, coral, and sea anemones.
