Is the genetic structure of Gran Chaco populations unique? Interregional perspectives on native South American mitochondrial DNA variation
This study reevaluates the hypothesis in Demarchi et al. (2001 Am. J. Phys. Anthropol. 115:199-203) that Gran Chaco peoples demonstrate a unique pattern of genetic diversity due to a distinct regional population history. Specifically, they found populations in the central part of the Gran Chaco, or Central Chaco, to have higher within- and lower between-population mitochondrial DNA (mtDNA) haplogroup frequency variation compared to populations in…
Mitochondrial DNA haplogroups in Amerindian populations from the Gran Chaco
Mitochondrial DNA from 141 individuals was typed for diagnostic restriction sites and the 9‐bp region V deletion to examine the distribution of the founding mtDNA lineage haplotypes in three Amerindian populations (Mataco, Toba, and Pilagá) who currently inhabit the Argentinian part of the Gran Chaco. All four lineages were identified in the three tribes and four population samples studied. Disregarding ethnic or geographic origin, haplogroups B …
Genetic Structure and Gene Flow in Gran Chaco Populations of Argentina
The Gran Chaco region of central South America has been settled by humans for only the last 4,000-5,000 years. To investigate population structure and variation in this region's indigenous population, we scored males from tribes of the Argentinean part of the Gran Chaco (Pilagá, Wichí, and Toba, representing two major language groups, the Mataco and Guaycurú) for a number of Y-chromosome polymorphisms. The markers included eight microsatellites (…

Human colonization of the central territory of Argentina
In this study we test several hypotheses about the peopling of the central territory of Argentina, archaeologically known as Sierras Centrales, by testing the association between four alternative models of the peopling of the area and cranial morphological variation through distance and matrix correlation analyses. Our results show that the ancient inhabitants of Sierras Centrales demonstrated close morphological similarities with the Patagonian …
Y-Chromosomal Evidence for a Founder Effect in Mbyá-Guaraní Amerindians from Northeast Argentina
To assess the paternal history of the Mbyá-Guaraní Amerindians of northeast Argentina, we examined the genetic variation in seven Y-chromosome loci: the binary marker M3 at locus DYS199, and six short tandem repeats (DYS19, DYS389I, DYS389II, DYS390, DYS391, and DYS393). The most striking finding is the high frequency among the Mbyá-Guaraní of Q3 lineages with the usually rare alleles DYS391*11 and DYS393*11, which could be the result of a founde…
Patterns of Ethnic, Linguistic, and Geographic Heterogeneity of Palmar Interdigital Ridge Counts in the Indian Subcontinent
Published data on palmar interdigital ridge counts (a-b, b-c, and c-d) among 57 populations from the Indian subcontinent were analyzed with reference to ethnic, socioeconomic, linguistic, and geographic affiliations of the studied populations. The spatial autocorrelation analysis suggests significant correlation between dermatoglyphic and geographic distances. The congruence with the ethnic semblance of the groups is also apparent in the data, an…

Apolipoproteins (apoproteins) and LPL variation in Mennonite populations of Kansas and Nebraska
Apoproteins (also known as apolipoproteins) have been studied extensively because of their role in lipid transport, association between specific genotypes and elevated serum lipid levels, and increased risk of heart disease. There is considerable genetic variation in the geographic distributions of these markers, with a north-south cline of the APOE*4 allele observed in Europe by Lucotte et al. ([1997] Hum Biol 69:253-262). This study compares th…
Spatial patterns of anthropometric variation in India with reference to geographic, climatic, ethnic and linguistic backgrounds
