 Lines of affiliation have also been traced to the Cueva and Coiba tribes, although some anthropologists suggest that the Cuna might belong to a largely extinct linguistic group.Some Cuna believe themselves to be of Carib stock, while others trace their origin to creation by the god Olokkuppilele at Mount Tacarcuna, west of the mouth of the Río Atrato in Colombia.Among all three Indian groups — the Cuna, Guaymí, and Chocó — land was communally owned and farmed.
