[QUOTE]Originally posted by Troll Patrol: [QB] [IMG]http://i371.photobucket.com/albums/oo160/brandonpilcher/b9bdb805-bd92-4544-9f56-0ba40133a41f_zpse13095c4.jpg[/IMG] Ps. Nubians are within the same line of the dendrogram. As the assumed populations with similar [b] postcranial variable set.[/b]. Anyway, I can't see what this variable set implies, do you? In older studies the author Holliday TW. clearly shows that Africans, historically, overall are tropical adapted. Whereas Arabs and Europeans aren't. Raxter also indirectly stated the same, by implying they became "quickly tropical" thou I think she had different intentions. LOL [QUOTE] Replacement predicts that the earliest modern Europeans will possess "tropical" body proportions (assuming Africa is the center of origin), while Regional Continuity permits only minor shifts in body shape, due to climatic change and/or improved cultural buffering. This study tests these predictions via analyses of osteometric data reflective of trunk height and breadth, limb proportions and relative body mass for samples of Early Upper Paleolithic (EUP), Late Upper Paleolithic (LUP) and Mesolithic (MES) humans and 13 recent African and European populations.

[QUOTE]What we can say, however, is that in the Holocene, humans from southwest Asia do not exhibit tropically adapted body shape (Crognier 1981; Eveleth and Tanner 1976; Schreider 1975)....

New Series, Vol. 102, No. 1, 54-68 [QUOTE] In fact, in terms of body shape, the European and the Inuit samples tend to be cold-adapted and tend to be separated in multivariate space from the more tropically adapted Africans, especially those groups from south of the Sahara. [/QUOTE]--Holliday TW, Hilton CE. Body proportions of circumpolar peoples as evidenced from skeletal data: Ipiutak and Tigara (Point Hope) versus Kodiak Island Inuit. [QUOTE] Migration within a larger time framework took place ca. 15,000--18,000 BP, when the first Asian populations crossed the Bering Strait, ultimately founding the modern Amerindian population. Despite having as much as 18,000 years of selection in environments as diverse as those found in the Old World, body mass and proportion clines in the Americas are less steep than those in the Old World (Newman, 1953; Roberts, 1978). In fact, as Hulse (1960) pointed out, Amerindians, even in the tropics, tend to possess some ''arctic'' adaptations. Thus he concluded that it must take more than 15,000 years for modern humans to fully adapt to a new environment (see also Trinkaus, 1992). This suggests that body proportions tend not to be very plastic under natural conditions, and that selective rates on body shape are such that evolution in these features is long-term." [/QUOTE]-- Holliday T.(1997). Body proportions in Late Pleistocene Europe and modern human origins. Jrnl Hum Evo. 32:423-447 [QUOTE]Late Upper Paleolithic and Mesolithic Europeans should not exhibit tropically-adapted limb proportions, since, even assuming replacement, their ancestors had experienced cold stress in glacial Europe for at least 12 millennia. [...] Additionally, brachial and crural indices do not appear to be a good measure of overall limb length, and thus, while the Late Upper Paleolithic and Mesolithic humans have significantly higher (i.e., tropically-adapted) brachial and crural indices than do recent Europeans, 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 is best explained as evidence for Replacement in the European Late Pleistocene, followed by gradual cold adaptation in glacial Europe.[/QUOTE]--Holliday TW J Hum Evol. 1999 May;36(5):549-66. Brachial and crural indices of European late Upper Paleolithic and Mesolithic humans. [/QB][/QUOTE]
