An encounter with a puppy or a baby, it doesn't matter, can often draw out the same behavior, almost involuntarily. You know the one: A high pitched cooing, an exaggerated drawl, a tone beaming with unconditional love. Scientists call this "exaggerated prosody." To ordinary people, we know it as "the cute-sie voice."
New research reveals that dog brains are actually sensitive to this tone, which has surprising implications for how they evolved to be man's best friend.
