Abstract: A somatological survey on 216 people of Jingbo nationality living in Yunnan was carried out in July, 1986. The survey covered 105 adult males (from 24 to 60 years old) and 165 adult females (from 23 to 55 years old).
The results of the survey are summarized breifly as follows: Judging by all nonmetrical data, Jingbo nationality obviously belongs to the Mongoloids. Averages of most measurements in Jingbo nationality people are close to those of Han nationality. The average head breadth, face breadth, nose height and mouth breadth are much different from those of Han nationality, but are very close to those of minorities living in Yunnan. Most nonmetrical data are different with regard to sex. Al1 measurements are higher in males than in females. They belong to the thin physical type, containing less fat in their body.
In view of the cluster graph of kinship matrix for Jingbo and 7 groups of other minorities living in Yunnan, the physical character of Jingbo nationality is similar to those of Dai nationality, Ha nationality and Yi nationality.
According to these analyses we consider that Jingbo nationality belongs to East Asian pattern in physical characters, but at the same time there are some features of the South Asian pattern. They may originate from the same ancestor as other inhabitants living in Southwest Yunnan.
