The sexing of subadult remains has been an ongoing problem in physical anthropology for many years. This is due in part to the scarcity of subadult collections of known age and sex which are large enough to be used to develop and test analytical methods. Several methods have been devised but few have produced reliable results. In 1980, Weaver presented a method for sexing subadult ilia using a nonmetric trait (the raised versus nonraised auricular surface), which has an accuracy of 75% in fetal females and 92% in fetal males. His method has not been tested for reliability on a different subadult sample. An indirect test of Weaver's method was made on a sample of subadult South Dakota Arikara Indian ilia by comparing the ratio of raised to nonraised auricular surfaces with an expected 1:1 sex distribution. Bimodal sex distributions in the Arikara formed unrealistic sex ratios, following an age-related shift from a 6:1 raised/nonraised ratio in newborns to a 1:4 ratio in young adolescence. Significant age correlations were found both in the present study and in Weaver's published results. The age-to-sex correlations indicated no confounding in the present study. The results of this test suggest that auricular surface morphology is not sex specific in subadult ilia, but may be related to aspects of shape and morphology in pelvic growth.
多年来，亚成年遗骸的性别鉴定一直是体质人类学中一个持续存在的问题。部分原因在于已知年龄和性别的亚成年样本稀缺，其规模不足以用于开发和测试分析方法。虽然已经设计了几种方法，但很少有能产生可靠结果的。1980年，韦弗提出了一种利用非测量性状（耳状面隆起与否）对亚成年髂骨进行性别鉴定的方法，该方法对胎儿女性的准确率为75%，对胎儿男性的准确率为92%。他的方法尚未在不同的亚成年样本上进行可靠性测试。通过将耳状面隆起与未隆起的比例与预期的1:1性别分布进行比较，对南达科他州阿里卡拉印第安亚成年髂骨样本进行了韦弗方法的间接测试。阿里卡拉人的双峰性别分布形成了不切实际的性别比例，随着年龄增长，从新生儿的6:1隆起/未隆起比例转变为青少年早期的1:4比例。在本研究和韦弗发表的结果中均发现了显著的年龄相关性。年龄与性别的相关性表明本研究中不存在混淆因素。该测试结果表明，在亚成年髂骨中，耳状面形态并非性别特异性的，但可能与骨盆生长的形状和形态方面有关。
