Human faces interest me – their differences and similarities.
In particular, family resemblances and racial characteristics. Are these idiosyncrasies there for a reason? Are they purely for identification or do they communicate much more than this? If we were to lose these identifying traits – would we be losing what makes us different from all other species? Are we aware that we treat people differently based on what we see when we look at a face? Not only is this down to race, but also age, sex and appeal. The powerful message conveyed by the face is so often received too soon for us not to have judged by it.
