STEPHANIE FAYERMAN , PAULA TINKER Research on behaviour begins to converge on a clearer picture of human virtues and vices. Exploring the richness of human life involves many different skills - to understand, for instance, how each person's genetic and cultural inheritance react together.

But the benign conspiracy has sinister undertones -for the loyalty and comradeship that sustain each person and his society may also lead to conflict between groups.
