(p. 30) Based on numerous historical encounters with aboriginal tribes, we know [hunter-gatherers] often, if not regularly, complained about being hungry. Famed anthropologist Colin Turnbull noted that although the Mbuti frequently sang to the goodness of the forest, they often complained of hunger. Often the com-(p. 31)plaints of hunter-gathers were about the monotony of a carbohydrate staple, such as mongongo nuts, for every meal; when they spoke of shortages, or even hunger, they meant a shortage of meat, and a hunger for fat, and a distaste for periods of hunger. Their small amount of technology gave them sufficiency for most of the time, but not abundance.
