Аннотация:Interest in explaining scientifically the enormous territorial expansion of the Tupi has been an issue since 1838, now with a consensus: a common centre of origin existed, from which the Tupi fanned out, differentiating through distinct historic and cultural processes whilst keeping several common cultural features. But there is no consensus as to where the centre was located and where passed the routes of expansion. Scholars have often asserted this hypothesis, but contributed very little scientific proof. Since 1960, archaeological (site location, radiocarbon and thermoluminescent dating) and linguistic data (glottochronology, relationships among languages) have been brought to the scene.
