Remember that hunter-gather societies vary enormously. One could compare and contrast !Kung / Inuit / Australian Aboriginals but it is impossible to make a general statement about warfare and violence in hunting gathering societies. There is simply too much diversity.

Lastly, hunting gathering societies have existed for something like 100,000 years, in many different environments, and the ones we have anthropological records of have come into contact with non hunting gathering societies.

Do you have a specific hunting gathering society you are interested in?
