A hunter-gatherer or forager society is a nomadic society in which most or all food is obtained from wild plants and animals, in contrast to agricultural societies, which rely mainly on domesticated species. Anthropologists have remarked that the term foraging is a more appropriate description of the predominant food source for most non-agricultural groups: Gathering is a far more important source of food than is hunting for the majority of non-agricultural societies.
Foraging was the ancestral subsistence mode for the Peoples of Aiers. However, following the invention of agriculture, hunther-gatherers have been displaced by farming or pastorialist groups in most parst of Aiers. Only a few contemporary societies in modern Aiers are classified as hunter-gatherers, and many supplement, sometimes extensively, their foraging activity with farming and/or keeping animals.
