太行山猕猴跖骨性差
Sex Dimorphism of Metatarsal of Macaca Mulatta
摘要
Abstract
Determination of sex using metatarsals was carried out on a sample of 39 skeletons from the Taihang Mountains (12 males and 27 females). Seven measurements were taken on each metatarsal. Statistical analyses were performed using SPSS version 20. 0. Stepwise discriminant functions were performed using seven metatarsal variables. Only those variables that best distinguished between the sexes were selected and subjected to direct discriminant analy-sis. Statistically significant differences between sexes were found (p<0. 01) in most dimensions, but with no signifi-cant difference in the measurements between right and left metatarsals in either sex. In the stepwise discriminant func-tions the best variable selected was metatarsal length. Overall accuracies of the functions ranged from 79. 1% to 93. 0%, with correct sex assignment ranging from 54% to 89% for the male to 89% to 94% for the female for the o-riginal data, dropping slightly for cross-validation. The results showed that measurements of the metatarsals appear to be good discriminators of sex.关键词
