Efforts to determine the genetic relations among Tungusic languages have be
en dominated by a methodology that categorizes the entire family on the bas
is of a small number of sound correspondences and some shared inflectional
morphology, despite the fact that this evidence can be interpreted in contr
adictory ways. The approach, styled after traditional classification, which
uses a tree model, is even less successful in indicating the relationships
among languages at a finer level of detail. This article demonstrates that
two Tungusic languages, Evenki and Oroqen, which have long been treated as
a single language for classification purposes, are better treated as disti
nct linguistic varieties. The article raises fundamental questions about th
e current classification of Tungusic languages and suggests a renewed exami
nation of the role of dialect continua and contact languages in understandi
ng the composition of the family. Finally, we question whether a tree-based
model is appropriate for classifying languages that have had a high degree
of contact and are found in families or branches of a shallow time depth.*
