Measurements of height, face height, nose height, nose breadth, head length and head breadth from individuals living in 17 villages of six South American Indian tribes were compared using Mahalanobis's morphological distances and their partition into size and shape components. Total D2 values correlate well with estimates of linguistic differentiation, but not with geographic distances between tribes. Three of the six tribes were also studied for blood polymorphisms, and again measures of distances based on these haematological traits did not correlate well with the morphological ones. The shape component was about three times as important as size in contributing to the intertribal variation.
对来自六个南美印第安部落17个村庄居民的身高、面高、鼻高、鼻宽、头长和头宽进行测量，使用马氏形态距离及其按大小和形状成分的划分进行比较。总D2值与语言分化的估计值相关性良好，但与部落之间的地理距离无关。对六个部落中的三个部落也进行了血液多态性研究，同样基于这些血液学特征的距离测量与形态学测量的相关性也不佳。在造成部落间差异方面，形状成分的重要性约为大小成分的三倍。
