(Latin America) Genetic Study of Latin Americans Reveals History of Converso Migration #general

Jan Meisels Allen

A genetic study of over 6,500 Latin American individuals uncovered ancestry
that could be traced to North Africa and eastern Mediterranean >from several
centuries back. Historical records and genetic analyses indicate that Latin
Americans trace their ancestry mainly to the intermixing of Native
Americans, Europeans and Sub-Saharan Africans. The study could corroborate
family legends of Converso heritage. They found in the Native American
ancestry that about a quarter shared five percent or more of their ancestry
with people living in North Africa and the eastern Mediterranean, including
Sephardic Jews. The researchers timed the influx of Mediterranean ancestry
among Latin Americans to the Spanish colonization of Latin America. They
suggest that a number of recent Conversos left Spain for Latin America,
"using false documents" as they were prohibited >from leaving so by the
monarchy . The study shows that Conversos came to the Americas in
disproportionate numbers.

The researchers examined more than 500,000 autosomal SNPs typed in about
6,500 individuals who were born in Brazil, Chile, Colombia, Mexico and Peru.
They were then compared to 2,300 people from, all over the world. The study
was reported in Nature Communications and the can be found at:
They also collected data >from 42 populations representing five major
bio-geographic regions: Native Americans, Europeans, East/South
Mediterranean, Sub-Saharan Africans and East Asians.

Geneticists also found rare genetic diseases prevalent among Jews popping up
in Latin America.
