In cultural anthropology, sedentism (sometimes called sedentariness; compare sedentarism) is the practice of living in one place for a long time. , the large majority of people belong to sedentary cultures. In evolutionary anthropology and archaeology, sedentism takes on a slightly different sub-meaning, often applying to the transition from nomadic society to a lifestyle that involves remaining in one place permanently. Essentially, sedentism means living in groups permanently in one place. The invention of agriculture led to sedentism in many cases, but the earliest sedentary settlements were pre-agricultural. Initial requirements for permanent, non-agricultural settlements For small-scale nomadic societies it can be difficult to adopt a sedentary lifestyle in a landscape without on-site agricultural or livestock breeding resources, since sedentism often requires sufficient year-round, easily accessible local natural resources. Non-agricultural sedentism requires good preservation and storage technologies, such as smoking, drying, and fermentation, as well as good containers such as pottery, baskets, or special pits in which to securely store food whilst making it available. It was only in locations where the resources of several major ecosystems overlapped that the earliest non-agricultural sedentism occurred. For example, people settled where a river met the sea, at lagoon environments along the coast, at river confluences, or where flat savanna met hills, and mountains with rivers. Criteria for the recognition of sedentism in archaeological studies In archaeology a number of criteria must hold for the recognition of either semi or full sedentism. According to Israeli archaeologist Ofer Bar-Yosef, they are as follows: 1. Increasing presence of organisms that benefit from human sedentary activities, e.g. House mice Rats Sparrows 2. Cementum increments on mammal teeth Indications that hunting took place in both winter and summer 3. Energy expenditure Leveling slopes Building houses Production of plaster Transport of undressed stones Digging of graves Shaping of large mortars In many mammals dark cementum is deposited during winter when food is scarce and light cementum is deposited in the summer when food is abundant, so the outermost cementum layer shows at which season the animal was killed. Thus if animals were killed the year around in some area it suggests that people were sedentary there. Historical regions of sedentary settlements The first sedentary sites were pre-agricultural, and they appeared during the Upper Paleolithic in Moravia and on the East European Plain between c. 25000–17000 BC. In the Levant, the Natufian culture was the first to become sedentary at
