I am confused a little by the tone of this. Given that chimpanzees are known to violently raid neighboring groups, why would anyone expect that there is a "first" raid with humans?<p>I would think a default expectation is that warfare was always there and only got more advanced with tool use etc.?
I am confused about this article, I would assume raider bands would exist before full scale battles would have happened. 13,400 years ago is later neolithic, I am sure humans were raiding each other before that.
