项目摘要

A genealogical positioning of the Okinawa main land, Miyakojima and Ishigakijima populations in East Asia and Japan was carried out by using metrical and 17 nonmetric tooth crown traits. Dental plaster casts were collected from teen-aged modern inhabitants of the Okinawa main land, Miyakojima and Ishigakijima of the Ryukyu islands.The dentition of the Ryukyu islanders were metrically examined in terms of inter island variation and biological population affinity. Measurements were taken of the tooth crown diameter of the inhabitants in Miyakojima and Ishigakijima and compared with those of another region. Mesiodistal and labio(bucco)lingual crown diameters of all anterior teeth in Miyakojima and Ishigakijima were smaller than in Okinawa. The crown diameters of all teeth in Ishigakijima were smaller than in Miyakojima.The upper and lower first molars are the largest and the most stable teeth in the mesiodistal and bucculingual crown diameters and crown area, while the upper second premol … More ar and the lower first premolar the smallest on the Miyakojima and the Ishigakijima populations. The upper and lower second premolars are proportionately the largest teeth in the crown index. The buccolingual crown diameter and crown area were larger for male than female, showing significant sex difference, premolars and molars except upper second molar, on the Miyakojima, and upper first premolar, upper second molar, lower first and second molars on the Ishigakijima populations.In Ryukyu islands, tooth sizes were correlated with geographical locations. But when compared with posterior region the sizes of Miyakojima and Ishigakijima were geographically correlated, and another not. Metrical dental characters of the Miyakojima and Ishigakijima populations were compared with these from the others. The Miyakojima populations show close affinities to the Tanegashima and Yayoi populations, and the Ishigakijima similar to the Ainu and Jomon populations.Incidences of 17 nonmetric tooth crown traits were investigated on dental plaster casts which collected from teen-age modern inhabitants of the Okinawa main land and Ishigaki island of the Ryukyu islands. The incidences of the Okinawa main land and Ishigaki islands were compared with other 11 Japanese populations and other 35 Asian-derived populations. In East Asian populations, Okinawa main land and Ishigakiisland had intermediate characters between the northeast Asian(Sinodonty)and the Southeast Asian(Sundadonty). In the Japanese populations, three Ryukyu islands were overwhelmingly similar to the migrant group(Yayoi period in north Kyusyu, the Jomon period, and the modern Hokkaido Ainu). However, the residence of Sundadonty such as Jomonese in Tanegashima on of the Yayoi period suggests a residence of Sundadonty in past Ryukyu islands and late migration on Sinodonty to Ryukyu islands. In modern Ryukyu poppulations, the Ishigaki and the Okinawa main islanders show affinities to the Yayoi period in north Kyusyu and the modern Tanegashima populations, and largely differ from the modern Hokkaido Ainu, the Jomon period and the Yayoi period in Tanegasima.Some amount of cline from north to south in the Ryukyu islands might indicate the gene flow of Sinodonty from the northward. The dental evidences shown in this study may contribute to the establishment of biological relationships between Miyakojima and Ishigakijima populations. Less
利用计量和17个非计量牙冠性状对东亚和日本的冲绳主地、宫古岛和石垣岛种群进行了系谱定位。从冲绳主要陆地、琉球群岛宫古岛和石垣岛的现代居民中收集了十几岁的牙膏模型,从岛间变异和生物种群亲和力的角度对琉球岛民的牙列进行了测量。测量了宫古岛和石垣岛居民的牙冠直径,并与其他地区的居民进行了比较。宫古岛和石垣岛所有前牙的近远中舌冠和唇舌冠径均小于冲绳。在近远中、颊舌向牙冠直径和牙冠面积方面,上颌第一磨牙最大、最稳定,而上颌第二恒磨牙最大,最稳定Ar较多,第一前磨牙较低,宫古岛和石垣岛种群最小。在牙冠指数中,上颌第二前磨牙和下颌第二前磨牙是最大的牙齿。口腔舌冠直径和牙冠面积男性大于女性,性别差异显著,宫古岛上除上第二磨牙外的前磨牙和磨牙,石岛上的上第一前磨牙、上第二磨牙、下第一磨牙和第二磨牙在琉球群岛上的大小与地理位置有关。但与后部相比,宫古岛和石垣岛的大小在地理上是相关的,而另一个则不是。比较了宫古岛和石垣岛两个种群的测量牙齿性状。宫古岛种群与谷儿岛和弥生种群亲缘关系密切,石垣岛种群与爱奴和绳纹种群相似。对冲绳大陆和琉球群岛石垣岛十多岁现代居民的17个非公制牙冠性状进行了研究。冲绳大陆和石垣岛的发病率与其他11个日本人和其他35个亚洲人的发病率进行了比较。在东亚种群中,冲绳主岛和石垣岛介于东北亚(Sinodonty)和东南亚(Sundadonty)之间。在日本人口中,有三个琉球岛与移民群体(九州岛北部的弥生时期、柔门时期和现代的北海道爱奴)极为相似。然而,弥合时期的Sundadonty,如Jomese在Tanegashima On的居住,表明Sundadonty在过去的琉球群岛居住,并在Sinodonty上迁徙到琉球群岛。在现代琉球的流行中,石垣人和冲绳主岛居民与九州北部的弥生时期和现代谷儿岛的居民有很大的亲缘关系,而与现代北海道爱奴、绳纹时期和田内亚洲的弥生时期有很大的不同。琉球群岛中的一些自北向南的斜面可能指示了中华牙从北向南的基因流动。这项研究中显示的牙齿证据可能有助于建立宫古岛和石垣岛种群之间的生物学关系。较少
