[QUOTE]Originally posted by Kalonji: [QB] [i]The Epipaleolithic site of Jebel Sahaba (Sudan) was discovered in 1962, ca. 1 km from the east bank of the Nile, and ca. 3 km north of Wadi Halfa (the site is now submerged beneath Lake Nasser/Nubia). From 1962-1966, a total of 58 intentionally-buried skeletons were uncovered at the site. Diagnostic microliths suggestive of the Qadan industry as well as the site’s geology suggest an age of 14 – 12 ka for these burials. In this study, the body proportions of the Jebel Sahaba hominins are compared to those of a large (N =ca. 1100) sample of recent human skeletons from Europe, Africa, and the north circumpolar region, as well as to terminal Pleistocene “Iberomaurusian” skeletons from the northwestern African sites of Afalou (Algeria) and Taforalt (Morocco), and Natufian skeletons from the southern Levantine sites of El Wad and Kebara. [b]Univariate analyses[/b] distinguish Jebel Sahaba from European and circumpolar samples, but [b]do not tend to segregate them from North[/b] or Sub-Saharan [b]African samples.[/b] In contrast, [b]multivariate analyses[/b] (PCA, PCO with minimum spanning tree, NJ and UPGMA cluster analyses) [/b]indicate that the body shape of the Jebel Sahaba hominins is[/b] closest to that of recent Sub-Saharan Africans, and [b]different from[/b] that of either the Natufians or the [b]northwest African “Iberomaurusian” samples.[/b] Importantly, these results corroborate those of Irish (2000), who, using non-metric dental and osseous oral traits, found that Jebel Sahaba was most similar to recent Sub-Saharan Africans, andmorphologically distinct from their contemporaries in other parts of North Africa. This study was funded in part by NSF (grant number SBR-9321339).[/i] Can someone explain what is exactly different, and why this difference manifests itself in one method of comparing, and not the other.
