We are a lot less violent on average, though. Hunter-gatherer societies tend to war a lot. We don't see it as high-intensity conflict because of the low casualty numbers and lack of pitched battles. But when you look at it as percentage of the overall population, it turns out to be worse than our worst conflicts.

(To be clear, not all hunter-gatherer societies are like that. Some are more peaceful than others, and there are extremes like the Moriori. But the average is what it is.)
