. there is no evidence for that and that is not what modern isolated hunter gatherers do either.
I came across plenty of examples in my studies of anthropology. Of course it depends what you mean by “tribe”. Really large scale violence requires a certain amount of technology. As an example”Yanomamo: The Fierce People” by Chagnon details some such incidents and suggests they were not unusual. Well actually the men and children were killed, the nubile women were kept alive for .
See also the Torah / Old Testament for numerous genocides, though these were bronze/iron age people and also the historicity of the incidents is disputed.
This was not universal—the Kalahari Bushmen (now called the San people) did not do this, perhaps in part because their main weapon was a slow acting poison dart. An all-out war would kill everyone involved.
But rates of violent death among males were extremely high in hunter/gatherer societies often documented by early anthropologists (from reconstructing family trees) in the 30-50% range.
