存在或不存在的22个非测量性状记录在从奄美群岛，冲绳，和琉球群岛的崎岛的颅骨。利用Smith的平均离散度（MMD）统计、主坐标分析和邻接聚类算法，将其特征频率模式与东亚/东南亚和世界样本进行比较。结果表明，琉球样品与东亚/东南亚的“蒙古人”集群，并远离绳文/阿伊努集群。这些结果并不支持流行的观点，即阿伊努人和琉球人的共同起源。此外，基于形态学和遗传学数据支持本结论的证据，以及绳纹族和阿伊努族的种群独特性进行了讨论。
Presence or absence of 22 nonmetric traits was recorded in the crania from the islands of Amami, Okinawa, and Sakishima of the Ryukyu Islands. Their trait-frequency patterns were compared with the samples from East/Southeast Asia and the world using Smith's Mean Measure of Divergence (MMD) statistic, principal coordinate analysis, and neighbor-joining clustering algorithm. The results indicated that the Ryukyuan samples aligned with the East/Southeast Asian "Mongoloid" cluster and are far distant from the Jomon/Ainu cluster. These results do not support the prevailing view which favors a common origin of the Ainu and Ryukyuan peoples. Moreover, evidence based on morphological and genetic data supporting the present conclusion, and populational uniqueness of the Jomon and Ainu were discussed.
