Reconstructing Native American Population History
TLDR
It is shown that the initial peopling followed a southward expansion facilitated by the coast, with sequential population splits and little gene flow after divergence, especially in South America. Expand
Genetic Variation and Population Structure in Native Americans
TLDR
Evidence is observed of a higher level of diversity and lower level of population structure in western South America compared to eastern South America, a relative lack of differentiation between Mesoamerican and Andean populations, and a partial agreement on a local scale between genetic similarity and the linguistic classification of populations. Expand
Geographic Patterns of Genome Admixture in Latin American Mestizos
TLDR
An analysis of admixture in thirteen Mestizo populations from seven countries in Latin America based on data for 678 autosomal and 29 X-chromosome microsatellites found extensive variation in Native American and European ancestry among populations and individuals and evidence that admixture across Latin America has often involved predominantly European men and both Native and African women. Expand
The peopling of America: craniofacial shape variation on a continental scale and its interpretation from an interdisciplinary view.
TLDR
A geometric morphometric analysis of 576 late Pleistocene/early Holocene and modern skulls is presented suggesting that the classical Paleoamerican and Mongoloid craniofacial patterns should be viewed as extremes of a continuous morphological variation. Expand
Admixture in Latin America: Geographic Structure, Phenotypic Diversity and Self-Perception of Ancestry Based on 7,342 Individuals
TLDR
The geographic distribution of admixture proportions in this sample reveals extensive population structure, illustrating the continuing impact of demographic history on the genetic diversity of Latin America. Expand
Y-chromosome evidence for differing ancient demographic histories in the Americas.
TLDR
Age estimates based on Y-chromosome microsatellite diversity place the initial settlement of the American continent at approximately 14,000 years ago, in relative agreement with the age of well-established archaeological evidence. Expand
Autosomal, mtDNA, and Y-chromosome diversity in Amerinds: pre- and post-Columbian patterns of gene flow in South America.
TLDR
Admixture analysis of the Colombian populations suggests an asymmetric pattern of mating involving mostly immigrant men and native women, and the concordance of these estimates does not support an important difference in migration rates between the sexes throughout the history of South Amerinds. Expand
African‐derived South American populations: A history of symmetrical and asymmetrical matings according to sex revealed by bi‐ and uni‐parental genetic markers
TLDR
The most consistent finding was the introduction of European genes through males, but the results differ in the several communities, indicating the importance of local factors in such interactions. Expand
Genetic evidence for two founding populations of the Americas
TLDR
It is shown that some Amazonian Native Americans descend partly from a Native American founding population that carried ancestry more closely related to indigenous Australians, New Guineans and Andaman Islanders than to any present-day Eurasians or Native Americans. Expand
A genomewide admixture map for Latino populations.
TLDR
A advantage of the strategy is that the map focused on markers distinguishing Native American from other ancestries and restricted it to markers with very similar frequencies in Europeans and Africans, which decreased the number of markers needed and minimized the possibility of false disease associations.
