[QUOTE]Originally posted by zarahan- aka Enrique Cardova: [QB] [b]Tropical peoples replaced cold-climate types in Europe[/b] [QUOTE]: "The transition in Europe from Neandertals to “early anatomically modern” (Late Paleolithic) humans 40,000 to 25,000 years ago and subsequent changes in morphology within the latter group, are especially interesting in that they may provide evidence of adaptation following migration to a new climatic zone if these populations were derived from farther south, as suggested by the preponderance of current evidence (Klein 1999). The lack of change between European Early and Late Paleolithic samples in distal-to-proximal [URL=http://www.africanamericanculturalcenterpalmcoast.org/historyafrican/notes8.htm]limb[/URL] length proportions (crural and brachial indices) was initially puzzling in this regard because a reduction would have been predicted if climatic adaptation were taking place (Trinkaus 1981). However, more recent work has shown that relative to measures of trunk (vertebral column) height, limb length did decrease significantly within the Upper Paleolithic in Europe, beginning at proportions similar to those of sub-Saharan Africans and ending at proportions similar to those of modern Europeans (Holliday 1997a). Comparisons of long bone lengths to bi-iliac breadths in available European Upper Paleolithic specimens (nD15–19, about a third from the Early Upper Paleolithic) also indicate significant reductions in limb length to body breadth between the Early and Late Upper Paleolithic (unpublished results based on data given in Ruff et al. 1997, supplementary information). Thus, body shape did change significantly in Upper Paleolithic Europeans after exposure to colder climatic conditions, although the change was mosaic in nature, beginning with a general reduction in limb lengths followed by a reduction in distal-to-proximal limb element proportions."
