In memoriam Antonio Prevosti (1919-2011), a pioneer of genetics of natural populations

Prof. Dr. Antonio Prevosti was born on the 15th of February, 1919, at Barcelona where he grew up and lived with his wife Maria Monclús and his family until his death. Between the years 1939 and 1942 he registered at the University of Barcelona and finished his studies there with the"University Degree in Natural Science" obtaining the extraordinary award of his promotion. Immediately afterwards he started his research about the growth rate of Barcelona school children from two very different social groups at the Anthropology Laboratory of the University of Barcelona. The obtained results were published in his Doctoral Thesis (1948). Further investigations on quantitative traits in human populations improved his knowledge of statistical analyses and provided the basis for a scholarship from the Italian Ministry of Foreign Affairs to work at the Institute of Statistical and Demographical Sciences in Rome directed by Prof. C. Gini.

Necrópolis de incineración y prácticas funerarias en el noreste de la Penínnsula Ibérica durante el Bronce Final y la Primera Edad del Hierro

[spa]En este artículo presentamos un estado de la cuestión sobre las necrópolis de incineración del Bronce Final y Primera Edad del Hierro en el noreste peninsular. Para ello, analizamos el ritual funerario, la organización interna de las necrópolis y muy especialmente su arquitectura funeraria para, en base a ella, caracterizar el proceso de regionalización que se observa en el territorio.

Anàlisis antropològica de les restes neolítiques de la Caserna de Sant Pau (Biometria, Dentició, ADN i Microestriació Dentària).

Les restes esquelètiques analitzades corresponen tant al nivell neolític (n=26) com a l"època del bronze (n=2), encara que aquí es presenten tan sols els resultats de la població neolítica (taula 1). En tots els casos les sepultures són individuals, amb l"única excepció de la sepultura 20, on s"han recuperat les restes corresponents a un individu femení adult (CSP201) i un fetus (CSP202) (taula 1). Per tal de caracteritzar biomètricament la població s"ha emprat la metodologia proposada per Martin i Saller (1959), Brothwell (1981) i Bass (1971). La determinació del sexe s"ha realitzat a través dels caràcters sexuals secundaris del crani i de la pelvis, i se"n pot trobar una descripció més detallada a Estebaranz et alii (2007). En el cas específic de les paleopatologies es van seguir les recomanacions de Campillo (Campillo, 1977).

Buccal dental microwear and stable isotopes of El Collado: A mesolithic site from Spain,

This study examines the correlation between buccal dental microwear and stable isotopes. The buccal surface of post-canine teeth casts from El Collado, the largest Mesolithic site in Spain, were examined under Scanning Electron Microscope; photomicrographs were taken from the middle third of the buccal surface with magnification 100X. Only six individuals passed the criteria for buccal dental microwear analysis. The photomicrographs were treated by adobe Photoshop 8.01 to cover an area 0.56 mm² of middle third of buccal surface, the output photomicrographs were digitized using Sigmascan Pro 5 by SPSS. Then the correlation between buccal microwear pattern and stable isotopes of the same individuals, of the previous study of Guixe et al., 2006, was examined using a Pearson test. Statistical analysis revealed that there is no significant correlation between stable isotopes and buccal dental microwear of the people of the Mesolithic site of El Collado. The historical and archaeological documentation suggest that the Mesolithic people tended to consume marine food. Fish-drying techniques were used during the Mesolithic period which allowed the introduction of dust and sand to the fish. These abrasive particles affected the buccal dental microwear pattern, so that no correlation between the isotopes and microwear may be expected. This also suggests that the buccal dental microwear pattern exceeds dietary reconstruction to reconstruct food processing techniques.

El Etnólogo como Conservador de Museo

Con cierta frecuencia uno se plantea la cuestión de cuál es el estatus profesional o científico de un etnólogo ocupado en la museografía etnográfica. Y, asimismo, uno también se pregunta cuál es la clase de problemática con la que se enfrenta comúnmente este tipo de Etnología, y cuál es su función en el seno de las ciencias antropológicas. Y la respuesta que nos damos, siempre es la misma: esta problemática no podemos reducirla al marco estricto de la museografía. En realidad, debe plantearse como una extensión de la problemática específica y general en que se inserta la etnología de cada país (cf. Esteva, 1969). En otro sentido, el papel del etnólogo que ejerce como conservador de un museo etnográfico está vinculado con la situación de su ciencia en el mundo contemporáneo.

Èquids i gossos en l"economia i en els rituals. Resultats de l"estudi dels materials dipositats en el sitjar iberoromà del Serrat dels Espinyers (Isona, Pallars Jussà)

[cat]El Serrat dels Espinyers constitueix, per si mateix, un punt important en el poc conegut poblament ibéric del Pallars. En el panorama arqueològic català esdevé un cas únic pel que fa a la utiliztzació dels animals en activitats rituals vinculades tant a espais funeraris com domèstics, en particular pel volum i la qualitat de les dades aportades. L'anàlisi de les restes òssies animals i d'altes materials associats han procurart un conjunt de dades que permeten establir hipòtesis sobre els comportaments rituals de la societat ibèrica que va ocupar el jaciment. D'altra banda, es posa en evidència la importància de dos tàxons: els èquids i els gossos, i la seva relació amb l'activitat econòmica que hi va poder tenir lloc. [eng]Serrat dels Espinyers is an important site within the little known Iberian culture settlement of the Pallars area in Catalonia. Regarding the use of animals in ritual activities related to both domestic and funerary spaces, the data provided by this site are unique within the Catalan archaeology. The results obtained in the analysis of animal bones and other associated materials have allowed us to establish new hypotheses about the ritual behavior in Iberian society. Moreover, the importance of two taxa: horses and dogs, has been highlighted, as well as their relationship with the economic activity that could have taken place on the site.

Sobre l'origen de les activitats físiques i esportives

Han estat molt nombrosos els historiadors i antropòlegs que, al llarg deis anys, han formulat teories i interpretacions intentant explicar, des d'una perspectiva o una altra, el sorgiment i institucionalització de les activitats físiques i esportives. És evident que l'home -quant a ésser viu-, igual que els al tres membres del regne animal, sempre ha tingut una activitat motora. Ara bé, l'exercici físic humà no pot quedar reduït a un mer fenomen biològic. Ningú no negara l'existència d'un potencial fisiològic que en cada moment de l'evolució -des deis primats fins als homínids- determina la motricitat humana. Peró la presencia de l'home sobre la faç de la terra no és limita a un simple creixement biològic, desplegat en una serie de possibilitats biomecàniques, sinó que també té una inequívoca dimensió cultural que beu a les mateixes fonts de la humanització.

Del patrimonio natural de los peces al patrimonio cultural del pescado: el Espai del Peix de Palamós

By submitting a brief example of the production process in the maritime heritage and fishing, we try to show that, among the different maritime heritage production processes that are occurring today in the Costa Brava (Catalonia, Spain), different “logics” are guiding these processes, which are causing a real transformation of the concept of maritime heritage and practices associated with it

¿Por qué las mujeres con cáncer de mama deben estar guapas y los hombres con cáncer de próstata pueden ir sin afeitar? Oncología, disidencia y cultura hegemónica

El universo oncológico, aparentemente, constituye un ámbito de profundos consensos; aliviar el sufrimiento de pacientes y familias, la búsqueda de una cura efectiva o erradicar el estigma asociado al diagnóstico son objetivos que generan un amplio acuerdo social. Desde una perspectiva cultural, sin embargo, se constata la presencia de ciertas áreas de tensión y disidencia en torno al cáncer. En este artículo, aplicando conceptos analíticos de Gramsci y Foucault, se define en forma de decálogo lugares comunes que como el pensamiento positivo, la feminidad, la prevención o el espíritu de lucha conforman una cultura hegemónica en cáncer de mama enfrentada a los discursos de culturas subalternas como la feminista o ambientalista. Frente a la idea de unidad y consenso, el análisis de la literatura antropológica proporciona una imagen compleja donde la vivencia del cáncer, resignificando la enfermedad como un espacio de conflicto ideológico, es construida en términos de lucha de intereses y proyectos de control social.

A comparison of three established age estimation methods on an adult Spanish sample.

Most current methods for adult skeletal age-at-death estimation are based on American samples comprising individuals of European and African ancestry. Our limited understanding of population variability hampers our efforts to apply these techniques to various skeletal populations around the world, especially in global forensic contexts. Further, documented skeletal samples are rare, limiting our ability to test our techniques. The objective of this paper is to test three pelvic macroscopic methods (1-Suchey-Brooks; 2- Lovejoy; 3- Buckberry and Chamberlain) on a documented modern Spanish sample. These methods were selected because they are popular among Spanish anthropologists and because they never have been tested in a Spanish sample. The study sample consists of 80 individuals (55 ♂ and 25 ♀) of known sex and age from the Valladolid collection. Results indicate that in all three methods, levels of bias and inaccuracy increase with age. The Lovejoy method performs poorly (27%) compared with Suchey-Brooks (71%) and Buckberry and Chamberlain (86%). However, the levels of correlation between phases and chronological ages are low and comparable in the three methods (< 0.395). The apparent accuracy of the Suchey-Brooks and Buckberry and Chamberlain methods is largely based on the broad width of the methods" estimated intervals. This study suggests that before systematic application of these three methodologies in Spanish populations, further statistical modeling and research into the co-variance of chronological age with morphological change is necessary. Future methods should be developed specific to various world populations, and should allow for both precision and flexibility in age estimation.

Estudi paleodontològic de les restes humanes del jaciment de Forat de Conqueta (Santa Linya, Lleida)

L"estudi ha estat realitzat sobre restes dentals recuperades al jaciment de Forat de Conqueta. La majoria de les dents s"han trobat aïllades, fora del suport ossi, la qual cosa n"ha dificultat la identificació i l"estudi. Entre els objectius de l"estudi paleodontològic, volem destacar la determinació d"un nombre mínim i màxim d"individus a partir de les restes. L"estudi ha estat molt limitat a causa de la tipologia funerària (enterrament col·lectiu en cova) i del ritual d"enterrament (cremació parcial). El resultats provisionals assenyalen que el nombre mínim d"individus representats per la mostra estudiada és de 41 i que, d"aquests, fins a sis individus podrien pertànyer a un grup d"edat infantil o juvenil

A test of Suchey-Brooks (pubic symphysis) and Buckberry-Chamberlain (auricular surface) methods on an identified Spanish sample: paleodemographic implications

Forensic Anthropology and Bioarchaeology studies depend critically on the accuracy and reliability of age-estimation techniques. In this study we have evaluated two age-estimation methods for adults based on the pubic symphysis (Suchey-Brooks) and the auricular surface (Buckberry-Chamberlain) in a current sample of 139 individuals (67 women and 72 men) from Madrid in order to verify the accuracy of both methods applied to a sample of innominate bones from the central Iberian Peninsula. Based on the overall results of this study, the Buckberry-Chamberlain method seems to be the method that provides better estimates in terms of accuracy (percentage of hits) and absolute difference to the chronological age taking into account the total sample. The percentage of hits and mean absolute difference of the Buckberry-Chamberlain and Suchey-Brooks methods are 97.3% and 11.24 years, and 85.7% and 14.38 years, respectively. However, this apparently greater applicability of the Buckberry-Chamberlain method is mainly due to the broad age ranges provided. Results indicated that Suchey-Brooks method is more appropriate for populations with a majority of young individuals, whereas Buckberry-Chamberlain method is recommended for populations with a higher percentage of individuals in the range 60-70 years. These different age estimation methodologies significantly influence the resulting demographic profile, consequently affecting the biological characteristics reconstruction of the samples in which they are applied.

Pubic growth study: applicability in sexual and age diagnostic.

The growth of five variables of the ischiopubic area was analyzed from bone material from birth to old age. The main purpose was to evaluate its significance and capacity for age and sex determination during and after growth. The material used consisted of 327 specimens from four documented Western European collections. Growth curves were calculated by polynomial regression for two classical variables of the ischiopubic area (pubis length and ischiopubic index) and three new variables of the pubic acetabular area (horizontal and vertical diameter of the pubic acetabular area and the pubic acetabular index). None of the curves showed lineal growth, with the exception of the ischiopubic index and the masculine vertical diameter of the pubis acetabular area. Pubis length has the most complicated growth, expressed by a five-degree polynomial. All the variables are useful for adult sex determination, except the pubic acetabular index. The ischopubic index, vertical diameter of the pubic acetabular area and the pubic acetabular index seem to be good variables for sub-adult sex determination. For age estimation the best variables, in both archaeological and forensic remains, are the absolute measurements (pubic length, vertical and horizontal diameter of the pubis). However, pubis length is the best variable for age estimation because it can be applied until 25 years of age.

Sacral fusion as an aid in age estimation

The degree of fusion at the anterior aspect of the sacral vertebrae has been scored in 242 male and female skeletons from the Lisbon documented collection, ranging in age from 16 to 59 years old. Statistical tests indicate a sex difference towards earlier fusion in young females compared with young males, as well as a clear association between degree of fusion and age. Similar results have been found in documented skeletal samples from Coimbra and Sassari, and the recommendations stated by these authors regarding age estimation have been positively tested in the Lisbon collection. Although more research from geographically diverse samples is required, a general picture of the pattern of sacral fusion and its associations with age and sex is emerging. We also provide a practical example of the usefulness of the sacrum in age estimation in a forensic setting, a mass grave from the Spanish Civil War. It is concluded that the scoring of the degree of fusion of the sacral vertebrae, specially of S1-2, can be a simple tool for assigning skeletons to broad age groups, and it should be implemented as another resource for age estimation in the study of human skeletal remains.

Age-Related Tooth Wear Differs between Forest and Savanna Primates

Tooth wear in primates is caused by aging and ecological factors. However, comparative data that would allow us to delineate the contribution of each of these factors are lacking. Here, we contrast age-dependent molar tooth wear by scoring percent of dentine exposure (PDE) in two wild African primate populations from Gabonese forest and Kenyan savanna habitats. We found that forest-dwelling mandrills exhibited significantly higher PDE with age than savanna yellow baboons. Mandrills mainly feed on large tough food items, such as hard-shell fruits, and inhabit an ecosystem with a high presence of mineral quartz. By contrast, baboons consume large amounts of exogenous grit that adheres to underground storage organs but the proportion of quartz in the soils where baboons live is low. Our results support the hypothesis that not only age but also physical food properties and soil composition, particularly quartz richness, are factors that significantly impact tooth wear. We further propose that the accelerated dental wear in mandrills resulting in flatter molars with old age may represent an adaptation to process hard food items present in their environment.
