| dc.description | Se realizó un estudio métrico con 126 cráneos de Patagonia -38 no deformados (PN), 40 con deformación tabular erecta (PD) y 48 indeterminados (PI)- para evaluar si la deformación artificial produce diferencias craneanas significativas y determinar si alteran las distancias interpoblacionales entre cráneos no deformados. Se relevaron 45 mediciones y se realizó análisis de componentes principales y discriminante, donde se obtuvo que los grupos deformados y no deformados difieren significativamente. Los PI fueron clasificados mediante una función discriminante con p>0.80 en 23 no deformados (PCN) y 17 deformados (PCD). Con las 4 muestras resultantes y otro grupo amerindio de referencia, ARIKARA (ARIK), se hizo análisis discriminante para obtener las distancias D<SUP>2</SUP> de Mahalanobis: PN-PD (10.8**), PN-ARIK (22.8**) y PD-ARIK (30.4**). La distancia PCN-ARIK fue igual que PN-ARIK (22.8**) y la distancia PCD-ARIK (31.4**) no difiere en más del 3% de la distancia original. La inclusión de cráneos con deformación indeterminada no modificó significativamente las distancias intergrupales. Por cuanto la variación intragrupal en cráneos de Patagonia fue menor que la variación intergrupal contra Arikara, se concluye que el efecto de la deformación artificial puede ser menor que el de una diferenciación intergrupal entre cráneos no deformados. | |
| dc.description | A craniometrical study on one hundred and twenty-six Patagonian skulls ?38 undeformed (PN), 40 with anterior-posterior (tabular erecta) (PD), and 40 with "undetermined" deformation- was made. The aim was to set whether the artificial deformation acts significantly on the between-group undeformed cranial distances. Forty-five variables were measured on each skull and a discriminant and a principal component (PCA) analyses were performed. Both deformed and undeformed samples differed significantly between them. The undetermined skulls were reclassified by means of a discriminant function, with p>0.80, as 23 undeformed (PCN), and 17 deformed (PCD). To the four ?PN, PD, PCN, and PCD- samples, a new one -the male Arikara (ARIK)- was added as reference. The D2 Mahalanobis distances were: PN-PD=10.8**; PN-ARIK=22.8**; and PD-ARIK=30.4**. The PCN-ARIK distance was equal to the PN-ARIK one (22.8**), and PCD-ARIK (31.4**) did not differ in more than 3% from the original (PD-ARIK). The undetermined crania did not alter significantly the between-group distance. Furthermore, the within-group Patagonian cranial variation was lower than the Patagonia-Arikara one. We concluded that the effect of the artificial cranial deformation is not as strong as it is commonly accepted: in a within-group comparison it may produce lower distances than the obtained in a between-group undeformed comparison. | |
