[QUOTE]Originally posted by Swenet: [QB] [QUOTE] Originally posted by Lioness: yet it icould be consistent with the Brenna Henn back migration hypothesis, the reason for the cold adapted limb ratios and also brachycephalism of some of the Afalou ( as well as Achilli 2005 finding common U5 hgs between Lapps (Saami) and berber)[/QUOTE]Agree, but it should be noted that the Ibero-Maurusians are likely not cold-adapted [i]in their limbs[/i]. Mesolithic European and East Asians fossils also have relatively high limb proportions. In fact, Mesolithic Europeans have much higher crural and brachial indices than Ibero-Maurusians. Their crural and brachial index are at 85.5% and 77.5 respectively per Holiday 1997. Its simply a pleisiomorphic trait from their Upper Palaeolithic ancestors, and ultimate from Africans. What you want to look at is their bodyplan in its entirety or their absolute limb length, both of which are unlikely to retain a plesiomorphic state for as long as limb proportions. [i]Additionally, [b]brachial and crural indices do not appear to be a good measure of overall limb length,[/b] and thus, while the Late Upper Paleolithic and [b]Mesolithic humans have significantly higher (i.e., tropically-adapted) brachial and crural indices than do recent Europeans,[/b] they also have shorter (i.e., cold-adapted) limbs. The somewhat paradoxical retention of "tropical" indices in the context of more "cold-adapted" limb length [b]is best explained as evidence for Replacement in the European Late Pleistocene, followed by gradual cold adaptation in glacial Europe.[/b][/i] --Holiday, 1999 [QUOTE] Originally posted by Lioness: Capsians, referred in the article to as Ain Dokhara ,on the other hand, who replaced the Iberomaurusian according to this dendogram did have tropical limb ratios.[/QUOTE]Caution is advised here. Ain Dokhara is just a single specimen. I wouldn't be surprised if some European or Ibero-Maurusian sample diverged in the African direction as well. In fact, what I could make out from the blurred readcube rendering of the paper is that at least one Afalou specimen clustered with the North Africans. We're talking populations with all their variations, not isolated individuals. There is also the issue of whether the introduction of the Neolithic tradition from the Sudan area influenced the Capsians biologically. [/QB][/QUOTE]
