“On the spectrum of team aggression, street gangs are one step nearer to a preliterate raiding party than to terrorists and therefore they are perceived as less threatening -they only destroy themselves. Some aspects of gang behavior do parallel chimpanzee raids, but in an urban jungle. -Gang warfare- is driven by the two basic emotions that also fuel chimpanzee and preliterate warfare -territory and revenge, or just being from another neighborhood. Merely belonging to another gang is enough reason to justify an attack, as also happens with the chimpanzees of Gombe. Unlike terrorists who attack a perceived outgroup for ideological reasons, in the case of Al Qaeda by mounting attacks halfway across the world, gangs fight their neighbors for what they perceive as territory and resources.” SexViolenceEvolutionAggressionGangEvolutionary PsychologyChoneroMarasTiguerones Book:Sex and War: How Biology Explains Warfare and Terrorism and Offers a Path to a Safer World Source: Sex and War: How Biology Explains Warfare and Terrorism and Offers a Path to a Safer World
