摘要:

目的 呈现中国全新世人群下颌圆枕的表现程度,分析下颌圆枕的时代变异、人群间变异并进行相关原因探讨。 方法 用指定尺寸的种子,如花生、黄豆、南瓜籽等对下颌圆枕进行形象类比和组合描述,并进行不同时代、不同性别、不同地点间的比较。 结果 下颌圆枕有明显的性别差异,男性>女性;时代差异显著,表现为新石器>青铜铁器>现代;不同地点人群下颌圆枕比较中,姜家梁>新疆>土城子、喇嘛洞。 结论 全新世时期,下颌圆枕的隆起表现程度随时代发展而降低,下颌圆枕的表现程度差异可能与食物差异导致咀嚼压力的不同有密切的关系。

Abstract:

Objective To present the performance of mandibular torus of Chinese in the Holocene,to analyze the age variation and the intercrowd variation of the mandibular torus and to explore related reasons. Methods Image comparison and combination description of the mandibular torus with seeds of the specified size, such as peanuts, soybeans, pumpkin seeds, etc,and compare them in different eras,genders,and locations. Results The result showed that the male’s mandibular torus was distinctively stronger than that of the female. It was larger in the Neolithic Age than in the Bronze and Iron Age and the size decreased further as human beings moved into the modern era. In comparison of mandibular torus in different locations, Jiangjialiang was the largest, Xinjiang was the second, and Tuchengzi and Lamadong were the smallest. Conclusion During the Holocene period, the degree of bulging of the mandibular torus is reduced from time to time, and the difference in the performance of the mandibular torus may be closely related to the difference in mastication pressure caused by food differences.
