Résumé
Measurements of humeri from the Crystal River archaeological skeletal population (78 individuals) were analyzed. This canoe population from Central Florida dated from 12,000 to 7,000 B.P. The incidence of septal aperture was inversely related to cortical thickness differences but not related to the variables of skeletal robustness. The incidence of septal aperture and cortical thikness were significantly different by sex. The incidence of septal aperture was 2.5 times greater in females than in males. The mean of the cortical thickness was 5.28 mm in males and 2.64 mm in female. The sex and cortical difference explained the incidence of septal aperture up to 33.1%. These findings may suggest that the incidence of septal aperture in this population is related to nutritional stress experienced during childhood that remained on the humeri of adult females.
