For millions of years, our early ancestors ambled on this planet, navigating a very dangerous world. They did so by communicating effectively their needs, emotions, fears, and desires with each other. Impressively, they achieved this through the use of nonverbal communications such as physiological changes (flushed face), gestures (pointing hand), noises (grunting is not a word) and facial or body reactions (quizzical or frightened look). This has been part of our biological heritage for so long that we still primarily communicate nonverbally, not verbally, and why we need emotional icons in our written communication
