On that note, the recent aDNA (YDNA, mtDNA and at(autosomal) DNA) test results of the noted Kennewick Man, a Paleindian originating from the Columbia River basin, suggest shared ancestry with living NA groups. According to the most recent aDNA evidence his YDNA SNP haplogroup was Q...-M3, mtDNA HVR I X2a..., like the late NL Beo Chief Nonosabasutt-interesting! Here is the article link for the paper as published in Nature for any interested readers who wish to explore further details on the aDNA study, as cited from Deniekes Anthropology Blog (http://dienekes.blogspot.ca/):<br /> http://www.nature.com/nature/journal/vnfv/ncurrent/full/nature14625.html<br /><br />Supplementary Data (mtDNA, YDNA, and atDNA):<br /><br />http://www.nature.com/nature/journal/vnfv/ncurrent/extref/nature14625-s1.pdf<br /><br />Note that the atDNA results for Kennewick Man do not cluster close to Anzick, the latter clustering closer to Central and South American NA groups, suggesting that there may have been a North-South population cline in ancient North America, where the ancestors of the Anzick people migrated southward into Mesoamerica as a founding population, while the root population of Kennewick Man may have been a later incoming Beringian indigneous group autochthonous to the Cordilleran Corridor south of the LGM ice sheets or glaciers, or perhaps a remnant Paleoindian migration group originating from Eastern North America, migrating westward to the Columbia Drainage Basin after the emigration of Anzick kin groups further south. Note also that the autosomal results for Kennewick Man cluster closer to extant Pacific Northwest Amerindian groups and Algonquian groups of NE America (Maritimes), collated as a whole in combination with the YDNA (Q-M3) and mtDNA (X2a-root), seem to confirm an ancient migration route from the Columbia Basin for Proto-Algic (reconstructed proto-ancestor of Proto-Algonquian and Proto-Ritwan (Wiyot & Yurok in California), suggesting ancient continuity or convergence between genetics and linguistics-for the Algonquian language family at least. It would be interesting to see any future YDNA SNP test results on the Maritime Archaic Indian (7000BP) groups to see if they are consistent with YDNA Q-M3, or C3 (common in NL-NS Mi'kmaq).

The evidence in SA, as well as perhaps NA, seems to confirm a bottleneck resulting from a founder effect with resulting diversity deriving from drift and selection. The evidence seems to confirm once again the absence of polyphyletic and polymorphic diversity at the level of mtDNA (HVR I-II) and YDNA (STR-SNP), as attested for instance in Central Asia and Western Eurasia. I suspect that future full genome sequencing of autosomal SNP DNA, n(nuclear) DNA and x chromosomes will only merely reinforce these preliminary results. Here is the link:<br />http://www.nature.com/news/bone-dna-reveals-humanity-s-trek-into-south-america-1.17424<br /><br />As a final note, preliminary DNA testing of Paleo-American or Paleo-Indian skeletal remains such as the noted Kennewick Man are also revealing the same consistent pattern of genome diversity. The same argument can also apply to the reconstructed genomes of the now extinct Beothuk Indians of Newfoundland, for whom published and forthcoming to-be-published preliminary DNA studies are showing to be Native American with no Western European DNA introgression.

The research study shows an ancient link or geentic continuity (mtDNA D1) between a Late Pleistocene female skeleton, dated to 12,000-13,000 BP, discovered in an underwater cave in the Yucatan Peninsula, Mexico. Such interdisciplinary research, namely aDNA studies of human skeletal remains found in underwater archaeological sites, highlights the convergence of both disciplines. Such a parallel study may be extended some day in the distant future here in NL to help solve the puzzle or mystery of why there is a relative paucity of Beo skeletal samples today!<br /> <br />Title:<br />Late Pleistocene Human Skeleton and mtDNA Link Paleoamericans and Modern Native Americans <br />(Chatters et al 2014, Science, Vol. 344 (No. 6185), pp. 750-4)<br /><br />Link:<br />http://www.sciencemag.org/content/344/6185/750Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-5086026991280831425.post-62117306031489096152010-02-15T09:34:44.322-03:302010-02-15T09:34:44.322-03:30One thing that struck me in the article is how ear...One thing that struck me in the article is how early in the game we are getting this information for a Palaeoeskimo individual.
