Abstract
The genetic distances between the American Indians and the three major races of man, Caucasoids, Negroids and Mongoloids, were determined by using gene frequency data on 14 blood group and 12 protein loci. The results support the general view that the ancestry of the American Indian is predominantly Mongoloid. Using 30,000 years as the separation time between the American Indian and Mongoloid, the divergence time between the three major races of man was estimated to be 33,000-92,000 years.
摘要
通过使用14个血型和12个蛋白质位点的基因频率数据，确定了美洲印第安人与人类三大主要种族（高加索人种、尼格罗人种和蒙古人种）之间的遗传距离。结果支持了普遍观点，即美洲印第安人的祖先主要是蒙古人种。以美洲印第安人和蒙古人种之间30000年的分离时间为依据，估计人类三大主要种族之间的分化时间为33000 - 92000年。
