Abstract
Se informa sobre el análisis bioantropológico efectuado en un cráneo humano hallado en cabo Shirreff, isla Livingston, Shetland del Sur: Se discuten los resultados y se concluye sobre la base de las características de la glabella, procesos supraorbitarios y occipital, que pertenece a un individuo de sexo femenino. El grado de osificación de las sinartrosis y la erupción del tercer molar permiten inferir una edad aproximada de 21 años. La forma general del cráneo, los nasales largos y bajos, la presencia de tubérculos malares y zigomárico-posteriores y la sutura zigomaxilar en ángulo son características mongoloides; pero las órbitas muy altas y caídas, los procesos zigomáticos marcadamente hacia atrás y la presencia del «tubérculo de Carabelli» en la 3ª pieza dentaria, señalan características caucasoides, estimándose por tanto que se está en presencia de un individuo mestizo. Esta mezcla se corresponde bien con la de algunos pueblos indígenas del extremo austral de Chile, de comienzos del siglo XIX, producto de ·su mestizaje con los navegantes extranjeros cazadores de lobos marinos.
The bioanthropological analysis of a human skull found at Cape Shirreff, Livingston Island, Antarctica, is reported. Upon the basis of the characteristics of the glabella, the supraorbital and occipital processes, it is inferred that the skull corresponds to a human female. The degree of ossification of the synarthrosis, and the eruption of the 3rd. molar let us infer that the approximate age was 21 years old. The skull general shape, the long and low nasals, the presence of malar and zygomathic tubercles, and the angular zygomaxillar suture are indicative as of an individual of mongoloid characteristics, but the orbital high, the narrowness of the nasal bones, and the presence of the «Carabelli's cusp» in the 3rd molar indicate caucasoid characteristics which let us infer that we are infront ofa half-breed individual, as a result of the interbreeding with rhe foreign sailors and sealers. These half-breed people fit well with those indigenous people of the Southern end of Chile at the beginning of the XIX century.
