membership, and even the existence of a Macro-Penutian phylum is
disputed. If the inclusionist school is correct, the Macro-Penutian
phylum ranges from southern Alaska to central Chile. And, if the
inclusionist school is correct, the member cultures range from the
advanced Mayan culture of Yucatan to hunter/gatherer tribes of
California and Oregon. It is doubtful that most of the linguistic
disputes will ever be settled, since a great number of the disputed
languages are extinct and unrecorded.
