The Analysis of a B2 Mitochondrial Sub‐Lineage from the Chilean Andes Supports Complex Mobility Patterns Between Pre‐Columbian Societies in the Andean Region
Brief Communication
(Cambios y continuidades en la subsistencia e interacción entre sociedades cazadoras-recolectoras marinas y agro-alfareras durante el Holoceno tardío en el Archipiélago Septentrional), Patagonia, Chil…
Durante el Holoceno tardío en el archipiélago patagónico septentrional (~41°30′-47°S), convergerían sistemas culturales diferenciados, interrelacionándose grupos con tradiciones culturales portadoras de cerámica y economías basadas en la producción de alimentos (hortícolas) con grupos de cazadores-recolectores-pescadores marinos presentes desde el Holoceno medio. En este trabajo se evalúa los cambios y continuidades en los patrones de subsistenci…
An approach on the migratory processes in the north of Chile based on Y chromosome analysis
OBJECTIVES: Northern Chile is an area characterized by a complex cultural and demographic trajectory. During the last few centuries, this complex trajectory has become the destination of intra- and intercontinental migratory waves. In this study, we analyzed the Y chromosome to evaluate how migratory and admixture patterns have affected the genetic composition of the populations in northern Chile compared with other populations of the country. ME…
Ancestry and admixture of a southernmost Chilean population
OBJECTIVES: Punta Arenas is a Chilean city situated on ancestral Aönikenk territory. The city was founded by 19th- and 20th-century colonists from Chile (Chiloé) and Europe (Croatia). This work uses uniparental and ancestry-informative markers (AIMs) to explore the effects of historic migratory and admixture patterns on the current genetic composition of Punta Arenas. METHODS: We analyzed mitochondrial DNA (mtDNA), Y-chromosome single-nucleotide …
The Chilean socio-ethno-genomic cline
Studies of the current Chilean population performed using classical genetic markers have established that the Chilean population originated primarily from the admixture of European people, particularly Spaniards, and Amerindians. A socioeconomic-ethno-genetic cline was established soon after the conquest. Spaniards born in Spain or Chile occupied the highest Socioeconomic Strata, while Amerindians belonged to the lowest. The intermediate strata c…
Human adaptation to arsenic in Andean populations of the Atacama Desert
OBJECTIVES: Quebrada Camarones, in the Atacama Desert, has the highest arsenic levels in the Americas (>1,000 μg/L). However, the Camarones people have subsisted in this adverse environment during the last 7,000 years and have not presented any epidemiological emergencies. Therefore, to solve this conundrum we compared the frequencies of four protective genetic variants of the AS3MT gene associated with efficient arsenic metabolization, between t…

Lactase non‐persistence and general patterns of dairy intake in indigenous and mestizo chilean populations
OBJECTIVES: Lactase persistence (LP) is a genetic trait that has been studied among different countries and ethnic groups. In Latin America, the frequencies of this trait have been shown to vary according to the degree of admixture of the populations. The objective of this study is to better understand the relationship between this genetic trait and dairy intake in a multiethnic context through a synthesis of studies conducted in four regions of …
Maritime Hunter-Gatherers in the Chonos Archipelago (43°50’–46°50’ S), Western Patagonian Channels
This article presents the current advances in archeological research on the Western Patagonian Channels, specifically the Chonos Archipelago (43°50’–46°50’ S). Based on a large spatial scale, we aim to contribute to the discussion of the dispersion and characteristics of the occupation of the Pacific coast of southernmost South America. Results show that all of the contexts recorded do not exceed 3600 cal BP. Site formation processes that may hav…
Ancient marine hunter‐gatherers from P atagonia and T ierra D el F uego
OBJECTIVES: The human population history from Patagonia and Tierra del Fuego has been of great interest in the context of the American peopling. Different sources of evidence have contributed to the characterization of the local populations, but some main questions about their history remain unsolved. Among the native populations, two marine hunter-gatherers groups inhabited the Patagonian channels below the 478S: Kawéskar and Yámana. Regardless …
Dna From Human Ancient Bacteria
We report a molecular methodology to obtain and analyse ancient bacterial DNA from archaeological dental calculus. Recent and archaeological DNA samples, as old as 4000 bp, were successfully extracted and amplified with species-specific PCR primers. We propose this approach in order to: detect the presence of specific bacterial species infecting past human populations; compare the composition of ancient oral microbiomes among human populations; a…
Archipiélago de los Chonos
We present new records of human occupation in the northern channels of Aisn, specifically the northwest coast of the Traigun Island, where four archaeological sites were found. The frequency of the findings and a significant volume of deposits suggest the importance of this area for indigenous human settlement. The sites are fish corrals and camping sites characterized by large accumulations of shell middens, emphasizing the discovery of historic…
Morphometric and Mtdna Analyses of Archaic Skeletal Remains From Southwestern South America
For decades anthropologists have discussed how and when the Americas were peopled. The prevailing view is that the first Paleoindians, ancestors of the Amerindians, arrived from Asia and Beringia to the American continent using a Pacific coastal route in pre-Clovis times. In this article skeletal remains dated 9000-4000 BP, excavated from archaeological sites in northern, central and southern Chile, were analyzed using geometric morphometric and …
Vinculos De Parentesco Por via Materna Entre Los Últimos Descendientes De La Etnia Kawésqar Y Algunos Entierros en Los Canales Patagónicos
El presente trabajo presenta los resultados obtenidos del estudio de polimorfismos de ADN mitocondrial de muestras esqueletales de origen Kawsqar provenientes de los sitios isla Englefield, Cueva de la Cruz, isla Capitn Aracena y canal Maule; y de individuos vivos pertenecientes a la etnia Kawsqar
MtDNA microevolution in Southern Chile's archipelagos
The genetic variability of four predominantly Indian populations of southern Chile's archipelagos was examined by determining the frequencies of four mitochondrial DNA haplogroups that characterize the American Indian populations. Over 90% of the individuals analyzed presented Native American mtDNA haplogroups. By means of an unweighted group pair method with arithmetic mean (UPGMA) dendrogram, a principal component analysis (PCA) derived from a …
Brief communication
A molecular characterization of alleles O1, O1variant (O1v), and the mutation G542A of the ABO blood group was performed in two Amerindian populations of Chile, the Aymara (n = 84) and the Huilliche (n = 75). In addition, a sample of 82 individuals of Santiago belonging to the mixed Chilean population was typed for comparative purposes. The polymorphisms which allow for molecular differentiation of different alleles of the O blood group were stud…
Microevolution in prehistoric Andean populations
Archeological evidence suggests that the iconographic and technological developments that took place in the highlands around Lake Titicaca in the Central Andean region had an influence on the cultural elaborations of the human groups in the valleys and the Pacific coast of northern Chile. In a previous communication, we were able to show, by means of a distance analysis, that a craniofacial differentiation accompanied the process of cultural evol…
Análisis De Adnmt De Restos Esqueletales Del Sitio Arqueológico De Tiwanaku Y Su Relación Con El Origen De Sus Constructores
Las hiptesis sobre el origen de las poblaciones que construyeron Tiwanaku basadas en informacin lingstica y etnohistrica son contrastadas haciendo uso de ADN mitocondrial antiguo, aislado de restos esqueletales. Se analizaron 18 muestras de las cuales 13 rindieron amplificados para los marcadores amerindios.

Mitochondrial DNA polymorphisms in Chilean aboriginal populations
The mitochondrial DNAs (mtDNAs) from individuals belonging to three Chilean tribes, the Mapuche, the Pehuenche, and the Yaghan, were studied both by RFLP analysis and D-loop (control region) sequencing. RFLP analysis showed that 3 individuals (1.3%) belonged to haplogroup A, 19 (8%) to haplogroup B, 102 (43%) to haplogroup C, and 113 (47.7%) to haplogroup D. Among the 73 individuals analyzed by D-loop sequencing, we observed 37 different haplotyp…
