We describe the geographic variation patterns of six dermatoglyphic traits from 144 samples in Eurasia. The methods of analysis include computation of interpolated surfaces, one-dimensional and directional correlograms, correlations between all pairs of surfaces, and distances between correlograms. There are at least two, probably three, distinct and significant patterns of variation. 1) A general NW-SE trend for pattern intensity, the main line index, and frequency of hypothenar patterns. 2) A trend from the Middle East to the north and east for frequency of axial triradius and of accessory interdigital triradii. 3) A patchy pattern for frequency of the thenar-interdigital 1. The results are compatible with a diffusion process between Europe and the peoples of Northern Asia, and possibly with a radiation of populations from the Middle East. The hypothesis of diffusion processes is supported by substantial interpopulation correlations between dermatoglyphic traits that contrast sharply with largely negligible intralocality correlations.
我们描述了欧亚大陆144个样本中六种皮纹特征的地理变异模式。分析方法包括内插曲面计算、一维和方向相关图、所有曲面之间的相关性以及相关图之间的距离。至少有两种，可能三种不同且显著的变异模式。1） 纹型强度、主线指数和小鱼际纹型频率呈现出一般的西北-东南趋势。2） 轴三叉点和指间副三叉点的频率从中东向北方和东方呈一种趋势。3） 大鱼际-指间1的频率呈现出斑驳的模式。这些结果与欧洲和北亚人群之间的扩散过程相一致，也可能与中东人群的辐射有关。皮纹特征在群体间存在显著相关性，而在局部地区相关性基本可忽略不计，这一事实支持了扩散过程的假说。
