What is it about?
We find that patterns of "phenocentrism"—being helpful to partners who appear similar and harmful to those who appear dissimilar to us—can easily evolve. Surprisingly, we find that spite—the willingness to harm others at a personal cost to oneself—evolves much more easily than altruism under certain circumstances.

Why is it important?
Our model may shed light on racist/ethnocentric behavior in humans, as well as similar behaviors in other species. It also provides an innovative way of modelling kin recognition and shows how this can generate discriminatory behavior.
