Limb characteristics of Yangshao residents in Wanggou site in Zhengzhou / 解剖学报

ABSTRACT

Objective To research the physical development of ancient inhabitants in the Neolithic Age. Methods Referring to Anthropometric Method , the main projects including humerus, tibia and femur of 108 human bone specimens unearthed from Wanggou site have been measured respectively. The limb bone index, sexual dimorphism and height have been compared and analyzed by Excel software. Results The overall development level of humerus and femur was higher than that of the control group in the same period and weaker than that of the Inner Mongolian group. The development of the middle femur was weaker than that of the control groups, with less muscle attachment. The difference in the brawniness of humerus between the genders was statistically significant (i = 0. 811, P>0. 05) , while the difference in the brawniness of femur was just the opposite (t = 0. 63, P>0. 05 ). The maximum variation range of the male femur was 40. 6 to 49. 4 cm, which was at a moderate low level in the control group. The average height of male was 166. 22 cm, ranging from 164. 47-167.68 cm. The average height of female was 158.06 cm, ranging from 154.02-160.34 cm; There was a significant difference in height between the genders (i = 4. 96, P<0. 01).The height of male is close to the south China group, lower than the comparison group in the same region and the north region, and that of female is at a higher level in the south region. The sexual dimorphism index of Wanggou formation was 5. 7 %. Conclusion The humerus, tibia and femur of the male in Wanggou group are stronger than that of the female, while the upper limbs of the male were stronger than that of the female, and there was no significant difference in the strength of the lower limbs. We suggest that there is no significant difference in nutrition between male and female of Wanggou site during their growth.
