项目摘要

A recent study on the Sangiran 17 skull reconstructed by the authors revealed tow morphological features which were regarded as functional adaptations. One is an extraordinal development of the nuchal area, suggesting the presence of thick neck and back muscles. This implies that the individual of Sangiran 17 was at least twice (muscularly) stronger than usual recent humans. The other is a facial structure in regard to the masseter of Sangiran 17 was short, thick and located anteriorly, near to the teeth, which means that the individual of Sangiran 17 should produce a strong chewing force but he could not open the mouth wide. He might have eaten tough vegetables. In regard to the pattern of cusp sizes in the molar tooth crown, the Sangiran series had much closer resemblance to the early African Hominids than to the modern sapiens.An analytical study using inductively coupled plasma (ICP) atomic emission spectrometry and ICP mass spectrometry, has produced minor and trace element data on bone remains of Sangiran. Evaluation of the newly obtained data suggests that several elements as Na and Sr seem promising for discriminating the original statigraphic provenance of the bone specimens from Sangiran, in addition to fluorine which has been previously certified to be an index element for the provenance discrimination. This geographical dating approach based on multielement analyzes was applied to some of the Sangiran hominid remains, and the results have given some implications on the tempo and in evolution of the early Javanese hominids.

作者对Sangiran 17头骨的最新研究揭示了拖曳的形态特征，这些特征被认为是功能适应的。一种是颈部区域的非洲发育，表明存在厚实的颈部和背部肌肉。这意味着Sangiran 17的个体至少（肌肉发达）是最近人类的两次（肌肉发达）。另一个是关于桑吉兰17号摩托的面部结构，较短，厚，位于牙齿附近，这意味着Sangiran 17的个体应该产生强烈的咀嚼力，但他无法张开嘴巴。他可能吃了坚硬的蔬菜。关于摩尔牙冠中的牙齿大小的模式，Sangiran系列与早期的非洲人类相比，与现代智慧相比。使用电感耦合血浆（ICP）原子发射光谱法和ICP质谱质谱，对Bornal eym sone songiran songiran songiran songiran songiran songiran songiran songiran n s sangangiran sangaNgiran。对新获得的数据的评估表明，除了先前已通过证明是出处歧视的指数元素外，还可以区分骨头标本的原始统计来源，这是Na和SR的几个要素似乎很有希望。这种基于多元分析的地理约会方法应用于一些sangiran hominid遗骸，结果对速度和早期爪哇人人类的演变产生了一些影响。
