The most distinctive characteristic of a human is it's face - itis unique among each individual (with the exception of identicaltwins). It is uncertain to me if whether we best identify otherhumans by their face due to special brain parts developed for this(there are people with disease that cannot recognize faces) or foractual very distinctive physical face forms; maybe it is acombination of this.

Anyway, the question is about evolution. Why would distinctfaces (or ability to recognize distinct faces) be something usefulthat would be retained by evolution? How is this better atsurvival?
