Language processing in humans depends on the neuronal connection between language areas in the brain. Until recently, this language network was thought to be uniquely human. Now, in a groundbreaking discovery about the evolutionary basis of our language, researchers of the Max Planck Institute for Human Cognitive and Brain Sciences, in collaboration with the Max Planck Institute for Evolutionary Anthropology and the Alfred Wegener Institute, have identified a comparable neuronal connection in the brains of chimpanzees.
