Well-known academics such as Jared Diamond, Stephen Pinker and Napoleon Chagnon have argued that warfare has played a key role in human evolution and has literally become a part of our nature as a species, while others, such as Margaret Mead, suggest that warfare emerges in particular social and cultural contexts, and is characteristic of some societies and not others. Utilizing data primarily from the field of social-cultural anthropology* (rather than biological, linguistic, or archaeological data), make an argument that war is either inherently natural and universal, or created in particular social-cultural contexts.
