There must be some evolutionary force acting to maintain this visual 'defect'.
Different parts of our brains process different things, like the facial features, voices and the gait of people we know. But it takes memory to weave them all together into a single picture.
Archaeological remains, traditional tribes and conflict among chimpanzees can tell us much about the history of human warfare.
An experiment providing interactive games for orang-utans is showing the potential for digital technology to enrich the lives of zoo animals.
