Peculiar Distribution of the Diego Factor among the Warrau

Abstract

THE Warrau are a tribe of South American Indians occupying the Orinoco delta and the adjacent swampy regions of the coast of British Guiana. They have been living in this region since prehistoric times. Being a group of about 9,000 people with a culture fundamentally marginal, they belong to the earliest inhabitants as yet traceable in South America1.
