摘要

目的通过对全新世215例成年女性下颌骨的测量项目的对比分析，探讨女性下颌骨测量性状的微观演化问题。方法对23个下颌骨测量性状进行测量，并运用SPSS 18.0统计学软件对各时代测量性状数据进行均值计算和不同时代间差异的显著性检验。结果从新石器时代经过青铜铁器时代到现代，下颌骨趋向于缩小。在不同的时代阶段，下颌骨各个性状的表现特点和变化幅度亦不相同。下颌体厚度的变化主要发生在新石器青铜铁器时代，下颌骨大体尺寸的缩小、下颌体高的减小主要发生在青铜铁器现代。下颌骨的时代变化首先体现在下颌体厚度上，然后才是下颌骨的大体尺寸和下颌体高。结论全新世女性下颌骨仍在进化，女性下颌骨的演化特点和趋势与男性下颌骨相似。

Abstract

Objective To better understand variation of Holocene Chinese mandibular morphology, a study was conducted on 215 adult female mandibles. Methods In this study, 23 mandible measurement traits were measured using traditional anthropometric method. SPSS 18.0 software was used to carry out the average calculation of measurement trait data of each era and the significance test among different periods. Results The overall size of female mandibles decreased from the Neolithic to Bronze-Iron Ages to present day. The linear characters of the female mandiblular features varied between different time periods. The decrease of thickness of the mandibular corpus primarily occurred during the Neolithic to Bronze-Iron Ages. The decrease in main size and body height was during the Bronze-Iron Ages to present day. It is possible that mandibles became thinner before the overall size decreased. Conclusion The comparison shows that the evolvement trend of the mandibular of the Holocene female is basically consistent with that of male.
