Omo Valley, northeastern Africa
Traduction non disponible · Original (anglais) · français indisponible
The Nyangatom are a pastoral-agricultural people of the Omo Valley, related in the excerpt to the Turkana of north-west Kenya. Their villages combine stock-raising, agriculture, food-gathering, hunting, and fishing, and are organized through clans and territorial sections rather than a centralized chiefly authority. The passage uses Nyangatom social organization and village-level biological variation to illustrate the value of cooperation between anthropology, parasitology, and historical research.

Le récit
The Nyangatom are presented as inhabitants of the Omo Valley who are related to the Turkana of north-west Kenya. Their villages range from about twenty to three hundred inhabitants, and their livelihoods combine stock-raising with agriculture, food-gathering, hunting, and fishing. This mixed economic life reflects the varied possibilities of the Omo environment and provides the social setting for the observations described in the passage.
Nyangatom society is organized according to a strict clan system complicated by territorial divisions. Political authority is notably decentralized: the passage states that no chief stands above the eldest son. Territorial organization therefore appears as a central principle of social structure, shaping both local identity and the distribution of communities across the valley.
The excerpt reports immunological differences between men from different villages, based on tests involving 300 people in 1971 and 359 in 1972. These differences were observed between villages rather than between the sexes, and a map of serum reactions to arboviral antigens corresponded closely to the territorial distribution of the people tested. The case is offered as an example of how biological and anthropological evidence may assist historical investigation.
