[QUOTE]Originally posted by the lioness: [QB] [QUOTE]Originally posted by xyyman: [qb] @ the Liar(s)...will post soon. It might of been Brace and /or Holliday [/qb][/QUOTE]LIES you don't know what the hell you are talking about. As of now, the Ainu have not even been mentioned at all on ESR. And the Jomon foragers study hasn't even been mentioned on ESR. -and it's not Brace or Holiday The very long Jōmon period is the time in Japanese prehistory from about 14,000 BC to about 300 BC, when Japan was inhabited by a Neolithic culture which reached a considerable degree of cultural sophistication, above all in pottery, despite limited development of agriculture and no use of metal. The relationship of Jōmon people to the modern Japanese and Ainu remains uncertain. Some consider the Japanese of today to be descended from a mixture of the ancient hunter-gatherer Jōmon culture and a largely different group who populated the later rice agriculture Yayoi culture. According to this theory these two major ancestral groups came to Japan over different routes at different times. Recent Y-DNA haplotype testing has led to the popularly accepted (though untested) hypothesis that haplogroup D2 Y-DNA, which has been found in some percentages of samples of modern Japanese, Ryukyuan, and Ainu males, may reflect patrilineal descent from members of a Jōmon period culture of the Japanese Archipelago.Analysis of mitochondrial DNA of Jomon skeletons from Hokkaido indicates that haplogroups N9b and M7a are likely a Jomon contribution to the modern Japanese mtDNA pool. Other studies show these haplogroups appearing with the greatest frequency in Ainu and Ryukyuan populations and much less in mainland Japanese, suggesting additional, later migrations to the Japanese islands. Mark J. Hudson of Nishikyushu University says Japan was settled by a Proto-Mongoloid population in the Pleistocene who became the Jōmon, and that their features can be seen in the Ainu and Okinawan people.The Jomon share many physical characteristics with Caucasians, but Brace says that they are a separate genetic stock. Recent anthropological studies suggest immigration from Siberia via Korea and/or Polynesia to be the ancestors of the earliest settlers in Japan. ____________________________________________________________ [b] Am J Phys Anthropol. 2008 Oct;137(2):164-74. Variation in limb proportions between Jomon foragers and Yayoi agriculturalists from prehistoric Japan.[/b] Temple DH, Auerbach BM, Nakatsukasa M, Sciulli PW, Larsen CS. Source Department of Anthropology, The Ohio State University, Abstract Variation in limb proportions between prehistoric Jomon and Yayoi people of Japan are explored by this study. Jomon people were the descendents of Pleistocene nomads who migrated to the Japanese Islands around 30,000 yBP. Phenotypic and genotypic evidence indicates that Yayoi people were recent migrants to Japan from continental Northeast Asia who likely interbred with Jomon foragers. Limb proportions of Jomon and Yayoi people were compared using RMA regression and "Quick-Test" calculations to investigate relative variability between these two groups. Cluster and principal components analyses were performed on size-standardized limb lengths and used to compare Jomon and Yayoi people with other groups from various climatic zones. Elongated distal relative to proximal limb lengths were observed among Jomon compared to Yayoi people. Jomon limb proportions were similar to human groups from temperate/tropical climates at lower latitudes, while Yayoi limb proportions more closely resemble groups from colder climates at higher latitudes. Limb proportional similarities with groups from warmer environments among Jomon foragers likely reflect morphological changes following Pleistocene colonization of the Japanese Islands. Cold-derived limb proportions among the Yayoi people likely indicate retention of these traits following comparatively recent migrations to the Japanese Islands. Changes in limb proportions experienced by Jomon foragers and retention of cold-derived limb proportions among Yayoi people conform to previous findings that report changes in these proportions following long-standing evolution in a specific environment.
