利用多元技术和合成地理图谱分析了39个独立基因频率在人类种群中的世界分布。大多数遗传变异与经度有关，南亚表现出居中的趋势。此外，纬度，尤其是离赤道的距离在某种程度上也起着重要作用，这表明气候因素施加了选择压力，尤其是对某些基因。
The world distribution of 39 independent gene frequencies in human populations is analyzed by multivariate techniques and synthetic geographic maps. Most genetic variation is associated with longitude, with South Asia showing a tendency to be central. Also latitude and, more particularly, distance from the equator play a significant role in a way that suggests that climatic factors exercise selective pressures, especially for certain genes.
