“…Entheseal changes were found to positively correlate with structural properties of long bones in other studies (Ibáñez‐Gimeno et al, ; Mazza, ; Michopoulou, Nikita, & Henderson, ; Niinimäki & Baiges Sotos, ; Weiss, ) and there is a global trend to observe postcranial morphological differences between societies with different subsistence practices. Therefore, statistically significant differences in humeral and femoral structural properties between hunter‐gatherers and Guaraní individuals are expected to be found upon controlling for body size.…”

“…In the H‐G sample, sex determination was based, primarily, on morphological sexual differences in the greater sciatic notch (Buikstra & Ubelaker, ) and the pubic portion of the os coxae (Phenice, ) and, secondarily, on the scoring system for sexually dimorphic cranial features (Buikstra & Ubelaker, ). When the skull and os coxae were missing, a set of discriminant functions for long bones specifically generated for the H‐G societies of the study area were applied to estimate sex (Mazza, ; for reliability tests of this method, see Mazza, ). Unfortunately, no discriminant functions were suitable for the Guaraní sample and the lack of anatomical connections between elements prevented the estimation of sex from the os coxae or cranium; therefore, it was decided to run a mixture analysis (Dong, ).…”

Introduction: Although pre-Hispanic hunter-gatherer and horticulturalist (known as Guaraní) societies from the lower Paraná River Delta (Argentina) presented differences in diet, pottery decoration, mortuary practices, and places of origin, differences in skeletal morphology between such groups have never been systematically explored. This work focuses on variations in humeral and femoral external linear measurements and derived structural properties of adult individuals from both societies as well as on variations in body mass and stature.Materials and Methods: Bone length, epiphyseal size, and midshaft breadth were measured in 82 adult humeri and 100 femora from hunter-gatherer and Guaraní archeological sites. Epiphyseal and midshaft robusticity, residual strength, midshaft shape and area, stature, and body mass were then estimated. Mann-Whitney tests were run to compare the hunter-gatherer and Guaraní samples.Results: Male Guaraní individuals presented stronger humeri and more robust femoral and humeral proximal epiphyses than hunter-gatherers. In addition, female Guaraní individuals showed rounder femoral diaphyses in comparison with female hunter-gatherers. Concerning stature, the Guaraní individuals were found to be shorter than hunter-gatherers, regardless of sex. No statistical differences were found in body mass.Discussion: Despite the fact that skeletal variations between Guaraní and huntergatherers could be a consequence of differences in mechanical loadings and genetic composition, bone robusticity is also positively correlated with increased age, but as the age composition of the Guaraní sample could not be estimated, skeletal variation between the samples could be a consequence of differences in age distribution.

Durante la última década el análisis de los cambios entésicos se ha incluido como parte de las investigaciones bioarqueológicas de diversas regiones de Argentina. En este trabajo se presenta una síntesis de los principales resultados alcanzados hasta el momento y se proponen algunos caminos para los futuros estudios. Los resultados más recientes desarrollados en Argentina tienen en cuenta, en general, los conocimientos más actuales. Se identifican, sin embargo, tres aspectos a ser considerados: 1) las distintas metodologías de registro empleadas; 2) el reconocimiento y control de los múltiples factores biológicos involucrados en los cambios entésicos, incluyendo la masa corporal, la talla y la robustez diafisial, además del sexo y la edad; y 3) la interpretación multifactorial de sus resultados. Se discuten los alcances que han tenido estos estudios en escalas locales y se proponen nuevos avances considerando interrogantes teóricos y metodológicos.

Introduction This study assesses the biological affinity between Late Holocene hunter‐gatherers that inhabited the region of the lower Paraná wetland (Argentina) at the end of the Late Holocene (1800–700 years BP). Methods Cranial nonmetric traits were registered in 159 adult individuals of both sexes. Biodistances were estimated between environmental and archaeological units through Smith's Mean Measure of Divergence, Mahalanobis distance, multidimensional scaling, Fst index, and R‐matrix. Biological distances concerning temporal and geographic distances between the archaeological sites were also evaluated through Mantel and partial Mantel tests. Results The environmental units showed statistically significant biodistances according to a distance spatial pattern but low genetic differentiation between groups. Additionally, some archaeological sites with median radiocarbon dates around 700 years BP also presented statistically significant biodistances. Conclusions Gene flow and genetic drift could be responsible for the observed biodistance results. These processes gave rise to different subpopulations of hunter‐gatherers with a shared material culture, whose territorial limits could have been reinforced around 700 years BP or earlier.
