Native American - Polynesian DNA...

There seems to be no shortage of DNA studies comparing Polynesians to
Pacific rim populations immediately to the West and Northwest of them
however similar studies comparing Polynesians to Pacific rim
populations to the East are as rare as hen's teeth.
In a link posted by Giselle Horvat 'mtDNA History of the Cayapa
Amerinds of Ecuador' it is pointed out that "...a relatively small
number of aboriginal Americans have been analyzed at the DNA sequence
level."
However the study does note that : "The similar frequency of the 9-bp
deletion in the Cayapa, compared to other South American Amerind
populations....emphasises the monophyletic nature of this deletion
mutation on a particular ancestral haplotype in the Americas. This B
lineage group constitutes a large proportion of the surviving
indigenous South Americans, and its tight association with indigenous
populations of remote Pacific islands indicates that itarose in the
same source population of Asia that contributed to a dispersal event in
two different directions...The mutation associated with this deletion
has to be as old as the first settlement, judging from its broad
distribution among Amerinds and Pacific Islanders."
And further on the study questions the accuracy of an earlier study by
Bonatto and Salzano (1997) because "...it was limited to an analysis of
haplogroup-A types only".
According to the authors: "We suggest that such a result would not have
been obtained if the other haplogroups had been included within the
analysis, since the results for these haplotypes would show the Cayapa
to be the closest genetic relatives of a group of non-Native Americans
(to date, the Kapingamarangi, a Polynesian outlier within Micronesia."
It certainly makes you wonder what might emerge if the geneticists
approached the whole subject of Polynesian origins in an unbiased and
objective manner.
