从动物考古学角度,依照成本与收益模式,根据猎物体型大小以及躲避猎捕的速度等标准将水洞沟第12地点的动物划分为高回馈率的大型动物和低回馈率的小型慢速动物以及小型快速动物三类,利用Simpson指数对三种类型动物数量分布的均衡度进行检测,发现第12地点远古人类对三类猎物的选择倾向性较低,即肉食食谱的均衡度较高.与Stiner的研究结果对比显示,第12地点的均衡度变化应该不是气候改变造成,而可能是肉食广谱革命的结果.与西亚地区的Natufian中石器文化相关数据的详细对比,则进一步证明了这一结论.
Animal archeology, according to the cost and benefit model, according to the size of the hunter size and escape the speed of hunting and other criteria will Shuiyougou No.12 animal spots divided into high-rate of return of large animals and low-rate small slow-moving animals And small fast animals, Simpson index was used to test the balance of the distributions of the three types of animals. It was found that ancient humans in the 12th place had a lower tendency of choice for the three types of prey, ie, the balance of the meat-eating recipes was higher. A comparison of Stiner’s findings shows that the change in equilibrium at Site 12 should not be caused by climate change but may be the result of a broad-based revolution in meat production, a detailed comparison with Natufian’s Mesolithic culture-related data in West Asia in conclusion.
