在更新世晚期，北美洲的殖民狩猎采集者敲击并使用了克洛维带凹槽的射弹尖。在扩张过程中，克洛维斯点的大小和形状发生了显着变化。考古学家知道文化漂变导致了这种变异，但是是否有可能仅靠这个单一来源就能如此迅速地产生如此多的变异？我们提出了几项实验研究中的第一项，探讨克洛维斯尺寸和形状变化是否会导致性能差异，重点关注不同克洛维斯点形式穿透目标的深度。我们的弹道实验表明，七种不同的克洛维斯点形式以不同的效率穿透同一目标。即使考虑了尖端横截面周长，两种尖端类型之间的穿透深度也存在显着差异。这些结果与以下假设相一致：不同时间和地点的克洛维斯人可能选择了特定的属性来为他们提供选择性的功能优势。
In Late Pleistocene North America colonizing hunter-gatherers knapped and used Clovis fluted projectile points. During their expansion the size and shape of Clovis points changed significantly. Archaeologists know that cultural drift contributed to this variation, but is it possible that this single source could alone generate so much variation so quickly? We present the first of several experimental studies exploring whether Clovis size and shape variation results in performance differences, focusing here on how deeply different Clovis point forms penetrate a target. Our ballistics experiment demonstrates that seven different Clovis point forms penetrated the same target with different effectiveness. Even after tip cross-sectional perimeter is accounted for, there are significant differences in penetration depths between two of the point types. These results are consistent with the hypothesis that Clovis people in different times and places may have chosen specific attributes to provide them with a selective functional advantage.
