“…The large concentration of deposits of shells all along the coast give proof to this activity (Orquera & Piana, ) and ethnographic information attributes carrying out the activity to Yamana women (Gusinde, [1937]). On the other hand, the bregmatic deformation attributed to female Yamana is compatible with the results described in the literature for the southern zone of the American sub‐continent (Del Papa et al, ; Guichón, ).…”

Objectives: Artificial deformation of the cranium in humans has been related to powerful environmental-cultural stimuli that modify vectors of growth and development when the cranium is still malleable. Osteological differentiation into deformed and nondeformed remains enables the morphological information of individuals that make up ethnic groups or populations to be separately contrasted, the invariant measurements of deformation to be identified, the information provided by archeological remains to be placed in a social context, the cranial variation to be related to genetic variation (individuals without deformation), and predictions to be made (in the absence of direct genetic information). Methods: With samples of reduced size and many variables, we propose a decision rule based on: (a) pre-selecting variables (Kruskal-Wallis and Λ-Wilks test); (b) applying logistic regression to obtain the optimal classification criterion; and (c) defining a multi-criterion decision rule to bring about greater robustness. Results: After applying the decision rule to a sample of 180 crania (71 from the Selknam, 74 from the Yamana, and 35 from the Alakaluf ethnic groups), it was possible to identify the Selknam men with frontal deformation and the Yamana women with flattening of the parietal regions at the height of the bregma. Conclusions: From there on with the information provided by the graphical representation of the populations in the most informative dimensions and the homogeneity contrast between sexes, we related the frontal deformation in Selknam men to dragging firewood, vegetable matter, domestic utensils, and heavy pieces of meat from the hunt. On the other hand, the flattening of the parietal areas at the height of the bregma in Yamana women is related to loading and transporting vegetables and animals in baskets or leather sacks.

“…These activities were described as everyday ones in populations of Tierra del Fuego (Gusinde, [1931]; Pique, ). On the other hand, the frontal deformation attributed to male Selknam is compatible with the results described in the literature for the southern zone of the American sub‐continent (Del Papa, Aimé, & Bonilla, ; Guichón, ).…”

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.
