Comparison of frame index reference percentiles in Argentine and European boys and girls
The comparison of the AR and EU FI references showed similar age and sex growth patterns. However, differences in percentile values between populations were observed, highlighting the importance of having local references for the evaluation of skeletal robustness

El 2 de julio de 2022 se realizó en Trelew, Chubut, Argentina, el primer encuentro de intercambio entre ciencias genómicas y conocimiento indígena. Este evento se llevó a cabo en el marco de un convenio entre el IDEAus-CONICET y la Dirección de Asuntos Indígenas de la provincia, con el objetivo de establecer una ciencia genética que se aliñe con los estándares éticos del quehacer científico asociado a las comunidades indígenas ancestrales y sus d…
El entierro múltiple de Cabo Dos Bahías (Patagonia Central Argentina)
En este trabajo se presenta nueva información sobre el estudio interdisciplinario del entierro múltiple de Cabo Dos Bahías, ubicado en la costa norte del golfo San Jorge y excavado en 1984 por el Sr. Rodolfo Brunet, aficionado a la arqueología y coleccionista de Puerto Madryn, Chubut (Argentina). Se realizaron análisis arqueológicos, tafonómicos, isotópicos (13C y 15N), bioantropológicos y dataciones radiocarbónicas. Los resultados permiten inter…
Estimación sexual en restos óseos de cazadores-recolectores de Patagonia central argentina
En el presente trabajo se comparan los resultados de la estimación de sexo en restos óseos humanos antiguos de individuos adultos de la Patagonia central argentina (N=42) a partir de dos métodos: por una parte, el estudio de estructuras de la pelvis, el cráneo, el húmero, el fémur y la tibia; por otra, el análisis molecular de secuenciación masiva (Next Generation Sequencing), mediante herramientas bioinformáticas validadas para ADN antiguo. Los …
Interdisciplinary identification of the skeletal remains of Catherine Roberts‐Davies, The first Welsh settler death in Patagonia, Argentina in 1865
In 1995, an almost complete human skeleton was found in Punta Cuevas, in the southern coast of Puerto Madryn, Chubut, Argentina. The burial traits and the associated objects suggested the skeleton might belong to Mrs. Catherine Roberts‐Davies, a middle‐aged woman who was the first dead person among the first group of 163 Welsh settlers that set sail on May 28, 1865, from Liverpool to Bahía Nueva, in Argentinian Patagonia. The aim of this paper is…
Decrease of external skeletal robustness (Frame Index) between two cohorts of school children living in Puerto Madryn, Argentina at the beginning of the 21st century
Background: It has been shown that modern life style with reduced physical activity can lead to lower bone accumulation. Also a decline trend in external skeletal robustness in children and young adolescents, measured by the Frame Index (FI), seems to have a parallel trend with the increase in overweight and obesity. Based on these findings we estimate that likely, the FI should be changed after a decade in the Argentinean population as well as i…
Recuperación, curación y estudios bioantropológicos de la Colección Frengüelli-Brunet
El objetivo del presente trabajo es dar a conocer la Colección Bioantropológica Frengüelli-Brunet, constituida por Rodolfo F. J. Brunet (1926-1996), naturalista y aficionado a la arqueología de la ciudad de Puerto Madryn, que se integra por restos humanos procedentes principalmente de la provincia del Chubut. En la actualidad esta colección se encuentra bajo el amparo de la Ley Provincial XI No 11 sobre “Régimen de las Ruinas y Yacimientos Arqueo…
Extended composite index of anthropometric failure in Argentinean preschool and school children
Objective: The Composite Index of Anthropometric Failure (CIAF) can only be applied to children under 5 years of age and does not contemplate obesity. The aim of this study was to propose an Extended CIAF (ECIAF) that combines the characterization of malnutrition due to undernutrition and excess weight, and apply it in six Argentine provinces. Design: ECIAF excludes children not in anthropometric failure (group A) and was calculated from a percen…
Estudio transversal de las parasitosis intestinales en poblaciones infantiles de Argentina
The frequency of parasitosis in Argentina corresponds to the country's complex mosaic of climatic and socioeconomic variability and shows a declining trend from north to south and from east to west
IV Taller de discusión sobre restitución de restos humanos de interés arqueológico y bioantropológico. Introducción
Desde el año 2011 se organizan reuniones anuales bajo el nombre de Taller de Discusión sobre Restitución de Restos Humanos de Interés Arqueológico y Bioantropológico (TaDiRH). En este ámbito de pluralidad académica y también ideológica, se discuten posibles estrategias comunes para dar respuesta fundamentalmente a las demandas de las comunidades sobre restitución de restos en el marco de la ley 25.517/01
Weight and height percentiles calculated by the LMS method in Argentinean schoolchildren. A comparative references study
The distribution of weight and height of schoolchildren, coming from most regions of the country, differs from those of national and international references. It should be advisable to establish a new national reference based on internationally recognized methodological criteria that adequately reflect the biological and cultural diversity of the Argentinean populations
Growth of school children in different urban environments in Argentina
The cities studied are in different stages of nutritional transition. Puerto Madryn is undergoing growing industrialization and urbanization and thus exhibits characteristics typical of an 'obesogenic' environment. General Alvear, a less complex urban centre, where some cultural patterns related to an agrarian way of life appear to have been retained, is situated at a less advanced stage
Origin of Fueguian‐Patagonians
A complicated history of isolation between Fueguian and Patagonian groups (originated by the appearance of the Straits of Magellan) as much as differences in population structure and life strategies constitute important factors in the clustering pattern of those groups. The aim of this work was to test several hypotheses about population structure and history of Fueguian‐Patagonians to propose a model that incorporates predictions for future stud…
Craniometric variation and the settlement of the Americas
New archaeological findings and the incorporation of new South American skull samples have raised fundamental questions for the classical theories of the Americas' settlement. The aim of this study was to estimate craniometric variability among several Asian and Native American populations in order to test goodness of fit of the data to different models of ancient population entries and dispersions into the New World. Our data set includes Howell…
The Settlement of Patagonia
Matrix correlation represents an innovative methodology to evaluate the explanatory power of several hypotheses by measuring their correspondence with observed morphological variation. In this paper, we view the origins of Patagonians from a matrix correlation approach. Personal and published data on nonmetric cranial traits were used to estimate a biological distance matrix involving five major groups from Patagonia and two from the northwest an…
Variations in sexual dimorphism in the skulls of rats subjected to malnutrition, castration, and treatment with gonadal hormones
Two groups of weanling rats were subjected to malnutrition, one with periodic injections of testosterone (males) and the other with estradiol (females). Two other groups (castrated males or castrated females) received normal feedings. In control animals, the relative weights (mg/gm body weight) of testes, seminal vesicles, and ovaries were greater than in malnourished rats. However, relative weights of those organs in hormone‐treated, malnourishe…
Effects of protein‐calorie malnutrition during suckling and post‐weaning periods on discontinuous cranial traits in rats
The influences of protein‐calorie malnutrition (PCM), and sex during lactation and post‐lactation on the frequencies of 25 discontinuous cranial traits (DCT), were investigated in Holtzman rats. Significant differences were observed in about 20% of the traits. Those traits were: the interfrontal fusion, the posterior incurvation of the palatine border, the double maxillary foramen, the double posterior palatine foramen, and the double frontal for…
