Social Organization of Foraging Bands Among the Hadza of Tanzania
Quick fact
Hadza camps have no formal leader, yet they maintain order through a strong ethic of sharing and leveling mechanisms that cut down anyone who tries to get too big for their britches.
Why this is interesting
When you imagine a hunter-gatherer band, you might picture a tight-knit, permanent group. But the Hadza of Tanzania do something surprising: their camps are constantly changing, with people freely coming and going.
