The question of where Proto-Tupí-Guaraní (PTG) was spoken has been a point of considerable debate. Both northeastern and southwestern Amazonian homelands having been proposed, with evidence from both archaeology and linguistic classification playing key roles in this debate. In this paper we demonstrate that the application of linguistic migration theory to a recent phylogenetic classification of the Tupí-Guaraní family lends strong support to a northeastern Amazonian homeland.
