Abstract
Since its discovery in southeastern Uzbekistan in 1938, the Teshik-Tash child has been considered a Neandertal. Its affinity is important to studies of Late Pleistocene hominin growth and development as well as interpretations of the Central Asian Middle Paleolithic and the geographic distribution of Neandertals. A close examination of the original Russian monograph reveals the incompleteness of key morphologies associated with the cranial base and face and problems with the reconstruction of the Teshik-Tash cranium, making its Neandertal attribution less certain than previously assumed. This study reassesses the Neandertal status of Teshik-Tash 1 by comparing it to a sample of Neandertal, Middle and Upper Paleolithic modern humans, and recent human sub-adults. Separate examinations of the cranium and mandible are conducted using multinomial logistic regression and discriminant function analysis to assess group membership. Results of the cranial analysis group Teshik-Tash with Upper Paleolithic modern humans when variables are not size-standardized, while results of the mandibular analysis place the specimen with recent modern humans for both raw and size-standardized data. Although these results are influenced by limitations related to the incomplete nature of the comparative sample, they suggest that the morphology of Teshik-Tash 1 as expressed in craniometrics is equivocal. Although, further quantitative studies as well as additional sub-adult fossil finds from this region are needed to ascertain the morphological pattern of this specimen specifically, and Central Asian Middle Paleolithic hominins in general, these results challenge current characterizations of this territory as the eastern boundary of the Neandertal range during the Late Pleistocene.
期刊介绍:
The American Journal of Physical Anthropology (AJPA) is the official journal of the American Association of Physical Anthropologists. The Journal is published monthly in three quarterly volumes. In addition, two supplements appear on an annual basis, the Yearbook of Physical Anthropology, which publishes major review articles, and the Annual Meeting Issue, containing the Scientific Program of the Annual Meeting of the American Association of Physical Anthropologists and abstracts of posters and podium presentations. The Yearbook of Physical Anthropology has its own editor, appointed by the Association, and is handled independently of the AJPA. As measured by impact factor, the AJPA is among the top journals listed in the anthropology category by the Social Science Citation Index. The reputation of the AJPA as the leading publication in physical anthropology is built on its century-long record of publishing high quality scientific articles in a wide range of topics.
