[QUOTE]Originally posted by osirion: [QB] I have been reading several reports on this and I think I will leave this alone for now. It appears to be too many unanswered questions. The best research I have found is as follows: Polynesian origins: Insights from the Y chromosome Bing Su*, Li Jin*,†, Peter Underhill‡, Jeremy Martinson§, Nilmani Saha¶, Stephen T. McGarvey‖, Mark D. Shriver**, Jiayou Chu‡‡, Peter Oefner‡, Ranajit Chakraborty*, and Ranjan Deka††,§ At this time, however, it is not possible to conclusively localize the center of origin of the Polynesian ancestors. mtDNA data suggested a spread of humans from Taiwan to Polynesia by way of a corridor through the Philippines and Indonesia. A pattern involving nucleotide substitutions in the control region of the mtDNA genome, dubbed the Polynesian motif (5, 6), was found in high frequencies in this corridor with the highest in Polynesia. Related types of this motif also were found in appreciable frequencies in this area of distribution and the Taiwanese populations showed the highest diversity. Based on these observations, the origin of the Polynesian motif was traced to Taiwan (6), which seemed to provide strong genetic support to the express train hypothesis. A recent reanalysis (8) of the published mtDNA data (3, 5), however, questioned the validity of this proposition. Richards et al. (8) argued that, based on assessment of divergence times for the motif and age estimates of the relevant populations, mtDNA data do not support a Taiwanese origin of the Polynesians. Rather, the evidence is more consistent with an island Southeast Asian ancestry, the homeland being in eastern Indonesia. [/QB][/QUOTE]
