姜家梁新石器时代遗址古人类的食谱

对河北省阳原县姜家梁新石器时代17个个体的人骨进行了9种微量元素的分析研究. 从聚类结果看不出姜家梁古代居民同种系多类型复合体居民之间体质发育差异的分布规律. 结合考古学文化研究和古DNA研究， 试验结果表明这17个个体在摄取食物的方式、 种类和数量上可能存在差异， 或许暗示这个群体中确实存在食物占有和分配上的差异或某种饮食习惯上的差异.

Dietary Analysis of Neolithic Human Skeletons from Jiangjialiang

The authors selected 9 trace elements as the basis of the dietary analysis.We analyzed 17 appropriate individuals.As we know,the ancient local residents of Jiangjialiang((Yangyuan) in Hebei Province,(China)) were multiplex clusters of the same race,however,we can not find out the distribution rule of physical development among the 17 people.With the researches of archaeology and ancient DNA,the authors think the main food resource of Jiangjialiang(residents) was vegetal,and the results of research show that there were differences in the manner,type and quantity of assimilating food,or hint they had a difference in dietetical habit because some residents got more carnous food than others.
