大荔颅骨的测量研究

本文报道大荔颅骨的一系列测量数据, 并且将其与中国, 欧洲和非洲的中更新世人类的相应数据进行比较, 发现大荔颅骨的测量数据大多没有超出中国和欧洲/非洲中更新世人的变异范围, 有的与中国中更新世人接近, 有的与欧洲和/或非洲标本更加接近。本文将这些结果与大荔颅骨的与中国古人类共同具有的其他测量和观察特征进行综合考虑, 建议大荔人群属于中国古人类连续进化链中的一员, 并且表现出中国古人类与欧洲和非洲古人类之间基因交流的形态证据。

A Metrical Study of the Dali Cranium

The maximum cranial length(g-op,M1)and glabello-inion length (M2) of the Dali cranium are 206.5mm and 190mm respectively. The maximum cranial breadth measured at the supramastoid crest is 150.5mm,and the maximum breadth of the reconstructed skull is 150mm at the level of temporal squama. The difference between the maximum cranial length and glabello-inion length in the Dali cranium and that in the cranium of Petralona are all longer than that in H. erectus from China. So the Dali cranium is closer to Petral...
