Natufians were cold-adapted

[QUOTE]Originally posted by Djehuti: [QB] [QUOTE]Originally posted by The Explorer: [qb] *For what it's worth, data referenced by Hershkovitz et al. 1995 puts the brachial index means of the [i]non-Hayonim[/i] Natufian samples at 77% and that of Hayonim Natufian samples in the range of 75-78. Apparently, the non-Hayonim collection of Natufian samples report a mean that is greater than that observed for either recent Europeans or Neanderthals. The Hayonim Natufian collection on the other hand is more varied, displaying means that range from those similar to recent Europeans to those similar to tropical African means. No data was given on the crural means. My educated guess is that Natufians are [i]generally[/i] likely to display [i]intermediate[/i] patterns of limb-proportions between that of tropical African means and those of recent Europeans, and not simplistic as the claim being attributed to Holliday, about Natufians being "cold-adapted". There is nothing particularly cold about the Levant. However, mixed ranges of limb-proportions may reflect biological contributions from groups ultimately originating from differing geographical locations from that of the Levant. *Natufian samples have been [i]collected from several [b]different[/b] sites[/i] namely: Hayonim cave, Kebara, El-Wad, Shukba, Eynan, and Nahal Oren. They are [i]noticeably [b]varied[/b] in their morphological manifestations[/i]; see for example... [i]The Natufian poplations sampled in the skeletal assemblages from Hayonim Cave, Kebara, El-Wad, Shukba, Nahal Oren, and Eynan [b]display a significant range of variability in both morphology and size[/b] (Table 1; see also Arensburg et al., 1975; Belfer-Cohen et al., 1992; Ladiray and Soliveres-Massei, 1988). [b]To speak about a “Natufian cranial morphotype” is thus simplistic and potentially misleading, although some generalizations can be made[/b]. The [b]similarities between Ohalo I1 H2 and the sample of Natufian[/b] males is [b]strongest in the configuration of the facial skeleton (e.g., nasal and orbital size, height and breadth of the upper face), while strong differences may be seen in the calvaria[/b].[/i] - Hershkovitz et al. 1995 The link provided by Truthcentric mentions nothing about the Natufians to my knowledge. As for the other citation provided without specified context, what indexes is the reader told about - brachial?, crural?, body linearity?, femoral head diameter?, etc. What specific Natufian samples were under study; are there noticeable variations across samples from different sites; is there a dominating trend within one sample vs. that of another sample from a different site, etc? I think these are obvious, if not fair questions to ask, so as to get a firm grip on from what angle the author (in this case Holliday) is arriving at his/her conclusion(s). *Furthermore, there is a bias in the correlative value of limb proportion means. For instance, in all likelihood, tropical body plans are accommodated by considerable eumelanin concentration in the skin, due to the solar radiation intensity of tropical regions. Shorter limb proportions on the other hand, don't correlate as well with possible skin melanin concentration. Think for example, that KhoiSan groups are considerably darker than Europeans, but "sub-tropical" limb proportions have been reported among them. Likewise, although light in tone, the Inuit are still noticeably darker than western Europeans, while displaying fairly small indexes for their limb proportions. So, "cold-adapted" must not be mistaken to mean "white". [/qb][/QUOTE]Finally, some light is shed by Explorer. Thanks. [/QB][/QUOTE]
