I saw this article last week and I've sent a message to the author asking
for more information not only about it but also information related to the
author's PhD Thesis.
We can recognize possible different Amerindian tribal
haplogroups/haplotypes/clusters because there has been deep linguistical and
etnohistorical divisions in the demographical and geopolitical history of
South America's peopling. The same could be said about the Iberian
Peninsula, possible different haplogroups/haplotypes/clusters strongly
related to different regions of Iberia. History shows the register of deep
rooted regional communities in different parts of Iberia with different
languages and different identities and political-statal apparatus projects
in a scale unknown in others parts of Europe.
The Amerindian and Iberian divisions met each other in South America and
there has been a fierce clash of different populational, linguistical and
statal plaques, just like opposing tectonical plaques. There has been a
Portuguese-Tupiniquim alliance, a Spanish-Guarani alliance and a
French-Tupinambá alliance. Brazilian society was the most expansionist one
because it was the most racially mixed one and warlike one in the European
colonial wars involving Portugal, Castile (Spain), France, Holland, England
in the fierce struggles for the control of South America from the 16th
Century to the 19th Century, so the borders do reflect the different history
of haplogroups/haplotypes/clusters of European and Amerindian origins, not
to mention the African ones. Different but somehow similar phenomenon in
both sides of the movemented Brazilian borders.

OBJECTIVE: To investigate the evolutionary and demographic history of the
Gaucho, a distinct population of southern Brazil, relating it to their
culture,
to assess possible parallel continuity. METHODS: Six binary polymorphisms,
an
Alu insertion polymorphism (YAP) and 12 short tandem repeat loci in the
non-recombining region of the Y-chromosome, as well as the sequence of the
first
hypervariable segment (HVS-I) of the mitochondrial DNA (mtDNA) control
region were
studied in 150 unrelated males born in the Pampa region of Rio Grande do
Sul.
RESULTS: Comparison of the results with the other Brazilian and Uruguayan
populations, as well as with their putative ancestors, indicated a stronger
male
Spanish influence than that observed elsewhere in Brazil, a former
Portuguese
colony. Extensive mtDNA analyses of their Amerindian component gave clear
indications of the presence there of material from extinct (Charrua), as
well as
extant (Guarani) tribes. CONCLUSIONS: The genetic analyses contributed in a
significant way to reveal that the known cultural continuity between pre-
and
post-Columbian Pampa populations was also accompanied by an extraordinary
genetic
continuity. Copyright 2007 S. Karger AG, Basel.
