The affinity of the dental remains from Obi-Rakhmat Grotto

The affinity of the dental remains from Obi-Rakhmat Grotto, Uzbekistan

 9 July 2007Accepted 19 March 2008

A human partial maxillary dentition and a fragmentary cranium were recovered from Obi-Rakhmat Grotto in northeastern Uzbekistan in 2003. Initial descriptions of this single juvenile (OR-1) froma Middle Paleolithic archaeological context have emphasized its mosaic morphological pattern; the dentition appears archaic, while certain morphological aspects of the cranial fragments may be more ambiguous. The present study provides a systematic and comparative analysis of the dental morphology and morphometrics of OR-1 to provide a more refined appraisal of its phenetic affinity vis á vis Neandertals and modern humans. Two analyses were performed. The first uses 28 non-metric dental traits scored from Neandertals, Upper Paleolithic, and Middle Paleolithic modern humans to assess the posterior probability of group membership for the Obi-Rakhmat individual. The second is a morpho-metric analysis of the first upper molar of OR-1. The results of both analyses suggest the dentition of OR-1is essentially Neandertal.

  1. “The results of both analyses suggest the dentition of OR-1is essentially Neandertal”. The current state of belief is such that if the mtDNA turned out to be ‘modern’ human the conclusion would then simply be that it was modern human.

  2. My thoughts exactly Terry.

    I was reading a little on the Grimaldi boy, where it mentioned how his teeth had similarites to several Neanderthal specimens, which is what lead me to post this as part of that research.

    Honestly, I think there would have to be a finding of both modern and ancient Mt/Y DNa in the same bone before they’d give an inch.

  3. “Honestly, I think there would have to be a finding of both modern and ancient Mt/Y DNa in the same bone before they’d give an inch”. And it amazes me that arguments for the complete separation of modern and archaic humans often seem to assume that such a thing is possible.
