摘要
扁平的颜面这一蒙古人种的颅骨特征可上溯到直立人时代。在新石器时代,颜面扁平度总的来看华北地区的要比华南的稍大些,但这种南北差别并无严格的地理界线;在现代,这种地理上的差别更不明显。山顶洞人类头骨化石的过小的颜面扁平度很可能是受外来“基因流”的影响的结果。
To examine the variation of upper facial flatness, the data on nasomalar angle of fossil, neolithic and modern crania from North and South China are presented and analyzed in this paper. The results show that the antiquity of Mongoloid upper facial flatness goes back to the age of Homo erectus, and the considerable upper facial flatness can be regarded as a plesiomorphic character. A geographical difference can be seen in the neolithic cranial series:the average size of nasomalar angle in North China is slightly larger than that in South China. However, this difference is reduced in the modern cranial series. Compared with the data listed in this paper, the nasomalar angles of crania from the Upper Cave in Zhoukoudian are too small to be as a character of regional continuity, and an influence of gene flow is suggested.
