That is a pretty good interpretation of the material I provided. At
the present, the mtDNA sequences of Polynesians, Micronesians and the
Melanesians who are related to them can not be demonstrated to be
*closer* to those of Native Americans than to those of some Asians.
How many Asians? I can't tell yet. Based upon very little data, it
appears that approximately 1/3 of the Asian sequences which have the
hypervariable region variants indicative of the Pre-Polynesian motif
have the 3 previously mentioned coding region variants which suggest a
more direct connection to the haplogroup B4 sequences of Oceanic
populations. Some present Native American sequences *may* be closely
related to the 1/3 that do, to the 2/3 that don't or to neither! If
the first scenario is determined to be true in the future (i.e. some
(few?) Native Americans related to closest known Asian relatives of
Polynesians) then I still think this information would be more
indicative of the source(s) of Native Americans than of the source(s)
of a great many Pacific Islanders.
