Concept
Hunter-gatherer
Summary
A traditional hunter-gatherer or forager is a human living an ancestrally derived lifestyle in which most or all food is obtained by foraging, that is, by gathering food from local naturally occurring sources, especially edible wild plants but also insects, fungi, honey, bird eggs, or anything safe to eat, and/or by hunting game (pursuing and/or trapping and killing wild animals, including catching fish). This is a common practice among most omnivores. Hunter-gatherer societies stand in contrast to the more sedentary agricultural societies, which rely mainly on cultivating crops and raising domesticated animals for food production, although the boundaries between the two ways of living are not completely distinct.
Hunting and gathering was humanity's original and most enduring successful competitive adaptation in the natural world, occupying at least 90 percent of human history. Following the invention of agriculture, hunter-gatherers who did not change were displaced or conquered by farming or pastoralist groups in most parts of the world.
Only a few contemporary societies of uncontacted people are still classified as hunter-gatherers, and many supplement their foraging activity with horticulture or pastoralism.
Hunting and gathering was presumably the subsistence strategy employed by human societies beginning some 1.8 million years ago, by Homo erectus, and from its appearance some 200,000 years ago by Homo sapiens. Prehistoric hunter-gatherers lived in groups that consisted of several families resulting in a size of a few dozen people. It remained the only mode of subsistence until the end of the Mesolithic period some 10,000 years ago, and after this was replaced only gradually with the spread of the Neolithic Revolution.
The Late Pleistocene witnessed the spread of modern humans outside of Africa as well as the extinction of all other human species. Humans spread to the Australian continent and the Americas for the first time, co-incident with the extinction of numerous predominantly megafaunal species.
