It is a major part of what separates us from the animals, the ability to verbalize our thoughts and understand the verbalizations of others. However, this evolutionary miracle is not exclusive to human beings – other species like dolphins and birds communicate regularly. Humans, however, have taken communication to such an advanced degree that we can verbalize even the most minute detail, and our brains are wired to understand them. Not only are we capable of multiple languages, we also have the capacity for non-verbal sign language. In fact, a recent study out of the University of Rochester focusing on sign language has reached a new conclusion on how the brain is wired for language.
