This isn't universally true. There are actually a very large amount of cultures where we have ZERO evidence of violence. E.g. for the Sámi in southern Scandanevia we have zero evidence of violence. Similarly the Tripolye culture in modern Ukraine/Moldova/Romania is famous for building megaworks and housing for up to 15,000 people. But despite this large population there is virtually zero evidence of walls/forts/moats/any defensive fortifications. Not specialized weapons.

Evidence of large-scale warfare in prehistoric periods is also extremely rare in general. Most violence we have evidence for seems to be driven by personal conflict. This could just be due to decreased population densities but the conclusion that humans have always widely used war or organized violence is certainly not supported by the existing evidence

Isn't it literally all of history??
