The question of whether warfare is encoded in our genes, or appeared as a result of civilization, has long fascinated anyone trying to get to grips with human society. Might a willingness to fight neighboring groups have provided our ancestors with an evolutionary advantage? With conflicts raging across the globe, these questions have implications for understanding our past, and perhaps our future as well.
The Enlightenment philosophers Thomas Hobbes and Jean-Jacques Rousseau had different visions of prehistory. Hobbes saw humanity’s earliest days as dominated by fear and warfare, whereas Rousseau thought that, without the influence of civilization, humans would be at peace and in harmony with nature.
The debate continues to this day. Without a time machine, researchers examining warfare in prehistory largely rely on archaeology, primatology, and anthropology.
