We report the results of an analysis of raw material selection patterns in the assemblages from two Late Pliocene in situ archaeological localities in the Makaamitalu Basin (Hadar, Ethiopia). While the same local conglomerate was used as a raw material source for both archaeological occurrences, different selection criteria are identified. At A.L. 894, selection for quality is subtle and the clearest selection is against non-homogeneous raw materials. In the A.L. 666 assemblage, higher-quality raw materials were selected and some rare raw materials reached the locality from unknown sources. A comparison between the Makaamitalu and other Oldowan assemblages reveals an overall shift toward higher complexity of both selectivity and transport behaviors from ca. 2.0 Ma onward, contrasting a typo-technological conservatism that pertains until ~1.6 Ma. It is hypothesized that an increase in complexity of behaviors related to raw material selection and acquisition involved changes in the intensity and fidelity of technological knowledge transmission.
我们报告了对 Makaamitalu 盆地（埃塞俄比亚哈达尔）两个晚更新世原地考古遗址组合中原料选择模式的分析结果。虽然两个考古遗址都使用了相同的本地砾石作为原料来源，但识别出了不同的选择标准。在 A.L. 894 中，对质量的选择是微妙的，最明显的选择是反对非均匀的原料。在 A.L. 666 组合中，选择了更高质量的原料，一些稀有原料从未知来源到达了该地点。将 Makaamitalu 与其他奥杜威组合进行比较，揭示了从大约 200 万年前开始，选择性和运输行为的整体复杂性朝着更高的方向转变，与直到大约 160 万年前的技术保守主义形成对比。据假设，与原料选择和获取相关的行为复杂性的增加涉及到技术知识传播的强度和保真度的变化。
