This book presents sociobiological studies which focus on the topic of in-group/out-group behaviour, a topic which includes ethnocentrism, xenophobia, nationalism and racism. In what sense are there biological, particularly evolutionary and genetic, explanations for intolerance of or aggression towards those who are not members of one's group? Such behaviour may be of adaptive advantage in the process of evolution by natural selection. However, particularly in the evolution of human nature and culture, such arguments are problematic. This book develops many relevant themes, covering issues that range from kin selection and altruism to national socialism and race relations.
This edited volume confronts an important issue: Are there evolutionary roots of xenophobia, racism, and nationalism? The various chapters look at the different aspects of this question. A sociobiological perspective (based on how reproductive success of humans affects their social behavior) is controversial. Nonetheless, if one is interested in how such a perspective could explain these behaviors, then this would be a useful volume to consider.
